Note Definition of EMC: The EMC refers to the capacity of equipment represented in terms of emission, which indicates the degree to which electromagnetic waves produced by equip- ment do not affect other communications equipment, and also in terms of immu- nity, which indicates the degree of resistance against electromagnetic distur- bance. 2-5-4 I/O Unit Wiring Note To satisfy the EC directives (low-voltage directives), provide reinforced insula- tion or double insulation for the DC power supply used with the I/O Unit. The following information must be considered when connecting electrical devices to I/O Units. Caution Tighten the terminal screws to a torque of 0.5 to 0.6 N � m. ! ! WARNING Do not apply voltages exceeding the input voltages to Input Units nor voltages exceeding the switching capacity to Output Units. Doing so may result in damage or destruction of the I/O Unit or result in fire. 29 MROELECTRIC.COM Wiring and Connections Section 2-5 Leakage Current (24 VDC) A leakage current can cause false inputs when using 2-wire sensors (proximity switches or photoelectric switches) or limit switches with LEDs on 24 VDC. If the leakage current exceeds 1.3 mA, insert a bleeder resistor in the circuit to reduce the input impedance, as shown in the following diagram. Input power supply SYSMAC R Bleeder resistor 2-wire method sensor, etc. R = 7.2/(2.4I–3) kΩ max. I: Device’s leakage current (mA) R: Bleeder resistance (kΩ) W = 2.3/R W min. W: Bleeder resistor’s power rating (W) The equations above were derived from the following equation: Input voltage (24) R � Input current (10) ≤ OFF voltage (3) I � Input voltage (24) R + Input current (10) W ≥ Input voltage (24)/R � Input voltage (24) � tolerance (4) Inrush Current The following diagram shows two methods that can be used to reduce the large inrush current caused by certain loads, such as incandescent light bulbs. Example 1 Example 2 OUT OUT R R COM COM Generating a dark current (about 1/3 of the Inserting a regulating resistance. rated current) through the incandescent bulb. Be careful not to damage the output transistor. I/O Line Noise Do not run CQM1 I/O lines in the same duct or conduit as multi-conductor cables of other control lines. If power cables carry more than 10 A at 400 V or more than 20 A at 220 V, they must be run parallel to I/O wiring. Leave at least 300 mm between the power cables and the I/O wiring, as shown in the following diagram. Low current cables 300 mm min. Control cables and CQM1 power lines 300 mm min. Power cables Grounding at resistance of 100 � max. 30 MROELECTRIC.COM Wiring and Connections Section 2-5 If the I/O wiring and power cables must be placed in the same duct (for example, where they are connected to the equipment), shield them from each other using grounded metal plates. In addition, use shielded cables for the I/O signal lines to improve noise immunity. Also, connect the shielded cables to the GR terminal of the PC. Control cables and Metal plate (iron) Low current cables CQM1 power lines Power cables 200 mm min. Grounding at resistance of100 � max. Inductive Loads When connecting an inductive load to an I/O Unit, connect a diode in parallel with the load. The diode should satisfy the following requirements: 1, 2, 3... 1. Peak reverse-breakdown voltage must be at least 3 times the load voltage. 2. Average rectified current must be 1 A. Inputs Outputs IN OUT Contact output Diode DC input Diode Transistor output COM COM ! Caution Do not apply a voltage exceeding the maximum permissible input voltage of the Input Unit or the maximum switching capacity of the Output Unit, otherwise the Units may be damaged, a malfunction may occur, or a fire may result. Input Devices When connecting an external device with a DC output to a DC Input Unit, wire the device as shown in the following table.

Malfunctions will occur if these connections are not met. 1, 2, 3... 1. The relationship between the PC’s ON voltage and the sensor’s residual voltage must be as follows: V ≤ V – V ON CC R 2. The relationship between the PC’s ON current and the sensor’s control out- put (load current) must be as follows: I (min.) � I � I (max.) OUT ON OUT Where, I = (V – V – 1.5 (residual voltage in PC))/R ON CC R IN If I is less than I (min.), connect a bleeder resistor, R. The resistance ON OUT constant of the bleeder resistor can be calculated as follows: R � (V – V )/(I (min.) – I ) CC R OUT ON 2 Power W � (V – V ) /R x 4 (tolerance) CC R 3. The relationship between the PC’s OFF current and the sensor’s residual current must be as follows: I � I OFF leak Refer to Leakage Current (24 VDC) earlier in this section for details. 32 MROELECTRIC.COM Wiring and Connections Section 2-5 The value of I is different for different Units, and is 1.3 mA for all Units for OFF which the OFF current is not listed in the Unit specifications.

CQM1-series PCs are classified as open-structure devices and must be installed inside a control panel. 2. Use reinforced insulation or double insulation on the DC power supply con- nected to DC Power Supply Unit and DC I/O Units. 3. CQM1-series PCs that meet EC Directives meet the common emission standard (EN50081-2) of the EMC Directives as individual products. When assembled into machinery, however, the noise generated by switching relay outputs can fail to meet the standard. When noise is excessive, surge killers must be installed or other measures must be taken outside of the PC. The measures required to meet the standard will vary with the load being driven, wiring, the configuration of the machinery, etc. The following examples show means of reducing noise. These means will only reduce the amount of noise and will not eliminate noise. They are pro- vided here as examples only. Requirement The following conditions can be used to determine if measures to reduce noise are necessary. Refer to the EN50081-2 Standard for details. • If the loads of the devices into which the PC is built are switched less than 5 times a minute, then no measures need to be taken. • If the loads of the devices into which the PC is built are switched 5 times or more a minute, then measures need to be taken. Examples Inductive Load Surge Connect a surge suppressor or diode in parallel with the load, as shown in the Suppressor following diagrams, when switching inductive loads. CR Method (AC or DC) The reset time will be increased if the load is a relay, solenoid, or similar device. Connect the CR between the load connections for 24-V and 48-V power supply voltages and between the contact connections for 100 to 200-V power supply voltages. The capacitor and resistors can be based on the following guidelines. C: 0.5 to 1 μF for each amp of contact current R: 0.5 to 1 Ω for each volt of contact voltage. You will need to adjust the above values depending on the characteristics of the load, relay, etc., based on the discharge suppression of the capacitor when the contacts are open and the current control effect of the resistor the next time the circuit is closed. 33 MROELECTRIC.COM Wiring and Connections Section 2-5 The dielectric strength of the capacitor generally needs to be between 200 and 300 V. Use an AC capacitor (without polarity) in an AC circuit. Inductive load CR Power supply Diode Method (DC Only) The energy stored in the coil is impressed on the coil as a current by the action of the parallel diode and converted to Joule heat by the resistance of the inductive load. Here, the reset time will be increased even more than for the CR method. The reverse dielectric strength of the diode must be 10 times the circuit voltage and the forward current must be at least as high as that of the load. If the circuit voltage is low enough, as it is for most electronic circuits, then the reverse dielec- tric strength of the diode can be as low as 2 to 3 times the circuit voltage. Inductive load Power supply Varistor (AC or DC) The method uses the fixed voltage characteristics of a varistor to prevent high voltages from being applied to the contacts. Here, as well, the reset time will be increase somewhat. Connect the varistor between the load connections for 24-V and 48-V power supply voltages and between the contact connections for 100 to 200-V power supply voltages. Inductive load Power supply Output Surge Current When connecting an output device having a high surge current (such as an incandescent lamp), use one of the following circuit configurations to protect the Output Unit. The following circuit lets the load draw a small current (about one third the rated current) while the output is OFF, significantly reducing the surge current. OUT L + R COM 34 MROELECTRIC.COM Wiring and Connections Section 2-5 The following circuit reduces the surge current by employing a current-limiting resistor.
