All Opto 22 SSRs operate conservatively at maximum internal junction temperatures of 110 °C. Use the equation below to calculate the maximum allowable heat sink thermal resistance for your application. It is good engineering practice to provide a margin for error instead of running the application right at the limits. If your application is near the thermal limit, it can be helpful to add a fan to move air across the heat sink. IMPORTANT: Thermally conductive grease must be used between the relay base and the heat sink. Sample Calculation 1 120-volt, 20-amp load; 50 °C ambient air temperature Model: 120D25 SSR. See the last two columns of the table on page 4 for thermal resistance and dissipation values for the 120D25. Also, see the note at the bottom of the table. Dissipation: 1.3 watts/amp Thermal resistance: 1.2 °C/watt Maximum junction temperature: 110 °C The calculation would be as follows: This calculation indicates that you should select a heat sink with a thermal resistance of less than 1.1 °C/watt.

Transformers are consisting of 1000 ohms in series with an LED. The LED will driven from positive saturation of the iron core to negative drop 1 volt, so the voltage across the internal resistor will be 1 saturation of the core each half cycle of the alternating volt less than the control voltage. voltage. Large inrush currents can occur during the first half The control current (I ) can be calculated from the control C cycle of line voltage if a zero-voltage SSR happens to turn on voltage (V ) as follows: C during the positive half cycle of voltage when the core is already in positive saturation. Inrush currents greater than 10 I = (V - 1)/1000 C C times rated transformer current can easily occur. The following Examples: table provides a guide for selecting the proper SSR for a given transformer rating. 3 VDC control voltage: I = (3 - 1)/1000 = 0.002 A (2 mA) C 32 VDC control voltage: I = (32 - 1)/1000 = 0.031 A (31 mA) C For control voltages above 32 VDC, an external resistor can be added in series with the SSR to limit the control current. Also, if the device driving the control current to the SSR is limited, you can limit the control current by using an external resistor (R ). e I = (V - 1)/ (R + 1000) e C C R = [(V - 1)/(I )] -1000 e C C To limit the control current to 2 mA, this simplifies to: R = 500 (V - 3) e C Solenoid Valve and Contactor Loads All Opto 22 SSRs are designed to drive inductive loads such as solenoid valves and electromechanical contactors.

Care should be taken in selecting a SSR for driving a heater load if the load is cycled on and off in a continuous manner as might occur in a temperature control application. Constant cycling can cause thermal fatigue in the thyristor chip at the point where the chip bonds to the lead frame. Opto 22 employs a thick copper lead frame for mounting the SCR chips in the power series SSRs to eliminate thermal fatigue failures. In addition, Opto 22 recommends operating any SSR at 75% rated current for cycling heater loads to ensure complete reliability.

Because of the limitations on semiconductor devices of be used in place of a mechanical relay to switch electricity to a the type used in SSRs, it is not practical to build single-device load in many applications. Solid-state relays are purely multi-throw SSRs. However, an alternative to multi-throw electronic, normally composed of a low current “control” side operation may be accomplished with multiple relays.

SSRs typically also feature electrical isolation to several thousand volts between the control and A: No. There is no way to guarantee that two or more relays load sides. Because of this isolation, the load side of the relay is will turn on simultaneously when operated in parallel.

SSRs do When the AC circuit voltage is at zero, no current is flowing. not have this problem; in the proper application, they could This makes it much easier and safer for the semiconductor be operated almost infinitely. device in the relay to be turned on or off. It also generates much less electrical EMI/RFI noise. Q : What are the limitations of using an SSR? Q : Can I use an AC SSR to switch DC? A: SSRs have a few limitations when compared to the capabilities of their mechanical counterparts. First, because A: No. Because of the zero-crossing circuit described above, the relay is semiconductor-based, it will never turn all the way the relay will most likely never turn on, and even if it is on, it on, nor off. This means that in the “on” state, the relay still has will likely not be able to be turned off, as DC voltage typically some internal resistance to the flow of electricity, causing it to never drops to zero. get hot. When in the “off” state, the relay will exhibit a small amount of leakage current, typically a few mA. This leakage Q : Can I use a DC SSR to switch AC? can conspire to keep some loads, especially ones with a high A: No. The semiconductor device used in Opto 22’s DC SSRs is impedance, from turning off! Additionally, SSRs are more polarized. It may break down and conduct for the portion of sensitive to voltage transients; while Opto 22 relays are very the waveform that is reversed in polarity. well transient-protected, if a relay gets hit hard enough a sufficient number of times, it will die or degrade. This makes Q : Can a DC SSR be used to switch an analog signal? SSRs less ideal for driving highly inductive electromechanical loads, such as some solenoids or motors. SSRs should also A: This is not recommended at all. First, the voltage drop across never be used for applications such as safety power the relay will cause signal loss. Second, the conduction disconnects, because even in the off state, leakage current is characteristics of the SSR are very non-linear at low operating present. Leakage current through an SSR also implies the voltages and currents. Use a mechanical relay; it will work presence of a potentially high voltage. Even though the relay much better. is not conducting a large amount of current, the switched terminal will still be “hot,” and thus dangerous.

To test an SSR, it is best to operate it at the actual line voltage it will be used at, driving a load such as a large light bulb. FAQ: SSR Troubleshooting Q : I have an SSR driving a load. The load turns on Q : My SSR does not function anymore. What may okay, but never seems to turn off, unless I remove have happened? power from the relay entirely. What might be hap- pening? A: There is no “normal” mode of failure for SSRs. They just stop working, by refusing to turn on or off. An improper installation A: This is normally a problem when using an SSR with a high- is often to blame for an SSR failure, as these are very simple, impedance load, such as a neon lamp or a small solenoid. reliable devices. If you have a failed SSR, it is important to look Loads like these often have relatively large initial currents, but at the normal operating parameters of that relay within the relatively small “hold in” currents. The result is that the off-state larger system to make sure that the relay being used is leakage current through the relay (see previous section) is appropriate to the application, and that the relay is being insufficient to cause the load to turn on to start with, but properly installed in the system. The three most common sufficient to keep it on, once started. The solution is to place a causes of SSR failure are as follows: power resistor, sized for 8–10 times the rated maximum • SSR improperly matched to load. The relay was leakage current for the SSR in parallel with the load. Make sure destroyed by overheating from carrying too much that this resistor has a high enough power rating for the current too long. application. For example, for a 5 mA leakage current at 120 • SSR insufficiently protected. Remember, a VAC, a resistor drawing 50 mA would be desirable. Using semiconductor is less tough than a simple metal contact. Ohm’s Law, the resistor value becomes 2,400 ohms. This Reverse voltages exceeding the PRV rating of the relay resistor will dissipate 6 watts, so a 7.5 or 10-watt size power will cause damage. Voltage spikes on the switched line, resistor should be used. perhaps from inductive kickback, may have destroyed Q : I have a new AC SSR driving a solenoid. It turns on one or more of the internal switching devices. okay once, but will not turn on again. What is going Remember to use snubbers, transorbs, MOVs, and/or on? commutating diodes on highly inductive loads. • SSR improperly installed. The SSR was not mounted to A: Some solenoids, some types of halogen lights, and some a large enough heat sink, or no thermal compound was types of strobe lights incorporate a diode in series with the coil used, causing the relay to overheat. Also, insufficient or filament. This causes the light to behave as a half-wave tightening of the load terminals can cause arcing and rectifier. Opto 22 SSRs have a built-in R-C snubber circuit in ohmic heating of the relay. Opto 22 recommends 35 parallel with the output. The capacitor in this circuit charges inch-pounds of torque on the load screw terminals. up but cannot discharge through the series diode, causing a Similar failures have also been attributed to the use of voltage to appear across the SSR terminals. Because the SSR crimp-on terminal lugs or spades; make sure such must see a zero voltage across the terminals to come on, it terminals are tightly crimped, and even drip some solder can’t turn on again in this situation. The solution here would into the joint to ensure good electrical contact and be to put a high-value resistor (several tens of Kohms) across protection from corrosion. the terminals of the relay, to allow the capacitor to drain its charge. Q : How can I test my SSR? A: It is not possible to test an SSR by the same methods used to test mechanical relays; a typical SSR will always show an infinite impedance to a resistance meter placed across the output terminals. There are a few reasons for this. First, the SSR requires a small amount of power to operate, derived from whatever voltage source is placed on the load terminals.
