The T48 accepts a variety of both thermocouple and RTD temperature probes. An output board contains the Main Control output, Alarm 1 output, Alarm 2/Cooling output, and/or Linear CONTROL AND ALARM OUTPUTS DC output. Since the controller is serviceable from the front of the panel, the In addition to the Linear DC outputs, there are up to three types of ON/OFF output board (on some models) may be easily changed or replaced without outputs.These outputs can be relay, logic, or triac for control or alarm purposes. disturbing the wiring behind the panel. No re-programming is required when Relay outputs can switch user applied AC or DC voltages.

Units with the linear output option require calibration procedure for the can control up to four SSR power units at one time. The Triac output supplies new linear output. one Amp of AC current for control of an external AC relay or triac device. Low-drift, highly stable circuitry ensures years of reliable and accurate temperature control. The recommended two year re-calibration interval is easily AUTO-TUNE accomplished via the programming menu. The T48 has an auto-tune feature which, on demand, automatically determines the PID control parameters for a particular thermal process. After REMOTE SETPOINT INPUT completion of auto-tune, the PID parameters are automatically optimized for The remote setpoint input facilitates the use of a remote signal to drive the that process and loaded into non-volatile memory. The operator may view and controller’s setpoint. The remote signal can be scaled independent to that of the modify the parameters as desired. controller’s range. The controller’s response to local/remote setpoint transfers Auto-tune may be invoked either at start-up or at setpoint, depending on the can be programmed. Also, the remote signal is filtered by use of an adaptive process requirements. An auto-tune programmable dampening factor produces filter. With this filter, relatively large filtering time constants can be used various levels of process control and response characteristics. without suffering from long settling times. The time constant and filter disable band are programmable. Additionally, the remote signal can also be velocity RS485 Communications limited (or ramped) to slow the controller’s response to changes in setpoint. This The RS485 communications option allows the connection of up to 32 devices results in a steady control response with no overshoot. on a single pair of wires with a distance of up to 4,000 feet and a maximum baud rate of 9600. Since the same pair of wires are used for both transmit and receive, only one way communication is possible at any given time. The controller has HEATER CURRENT MONITOR The T48 provides a direct readout of process heater current. This provides a programmable response time to allow the host device adequate time to release the communication line for a transmission. valuable information regarding single phase heater system integrity. It is especially useful on extruder and large oven applications where adjacent Selected parameters from the T48 can be interrogated or changed, and alarm output(s) may be reset by sending the proper command code via serial controllers mask the effect of a failed heater. The heater break alarm senses two types of heater system faults: communications. It is also possible to invoke Auto-tune through the serial port. Serial communications used with SFCRM software allows for easy controller 1) Main control output is “on” and heater current is below alarm value. This indicates failed heater or failed parts of heater, breaker trip, failed power parameter configuration by computer. control device, etc. 2) Main control output is “off” and heater current is above 10% of alarm value. HEATING AND COOLING SYSTEMS This indicates a failed power control device, wiring fault, etc. The T48 is available with dual outputs to provide heating and cooling to those processes that require them. For example, many extruder applications require both heating and cooling to maintain accurate extruder barrel and die LINEAR DC ANALOG OUTPUTS temperatures. The T48 is easily configured for these types of applications. The Main Linear DC output has independent scaling, programmable output update time and filter (damping) time. These parameters permit flexibility in process configuration. The output can be set for 0 to 10 V, 0 to 20 mA or 4 to 20 mA ranges, and can be configured for control or for transmission of temperature or setpoint values. 4 Configuration 2, Outputs (2-OP) CONTROLLER PROGRAMMING * “CYCt” - Enter time proportioning cycle time Front Panel Program Disable allows all of the controller’s set-ups to be “OPAC” - Select output control action locked-out from further operator intervention after the initial set-up. “OPLO” - Enter output power low limit The following four programming modes allow the controller to adapt to any “OPHI” - Enter output power high limit required user-interface level: “OPFL” - Enter probe fail power preset “OPdP” - Enter output control dampening Unprotected Parameter Mode “CHYS” - Enter ON/OFF control hysteresis Protected Parameter Mode “tcOd” - Select auto-tuning dampening Hidden Function Mode “ANtP” - Main Linear DC analog output range Configuration Parameter Mode “ANAS” - Main Linear DC analog output source “ANut” - Main Linear DC analog output update time UNPROTECTED PARAMETERS MODE * “ANLO” - Main Linear DC analog output scaling low The Unprotected Parameters Mode is accessible from the Normal Display “ANHI” - Main Linear DC analog output scaling high Mode when program disable is inactive or when the proper access code number Configuration 3, Parameter Lock-Outs (3-LC) * from the Protected Parameter Mode is entered.

PLASTICS EXTRUDER APPLICATION Several T48 controllers are employed to control the temperature of a plastics extruder. Each T48 controls a heating element and a cooling water solenoid to maintain each extruder zone at the desired temperature. The Heater Current Monitor option is used to provide a readout of the heater current. The multi-function User Input can be programmed to allow selection of manual operation when connected to common. This allows the user to hold the control output of the controller during abnormal process conditions. OEM PAINT SPRAYER APPLICATION An OEM manufacturing spray painting equipment utilizes the T48 to maintain optimum paint temperature. In addition to the low cost, the 1/16 DIN package size permits the OEM to design temperature control into various sized painting equipment, from small hand sprayers to large paint booths. The heating element used to heat the paint, is connected to the Main Control Output (OP1) programmed for On/Off control. Alarm 1 is programmed as Band Inside Acting, so that as long as the paint temperature is within manufacturer’s specifications for temperature, the “GO” light is on. Alarm 2 is programmed as Band Outside acting so that the “NO GO” light is lit when the paint temperature is more than 12° outside the manufacturer’s specifications of 140 to 150°F. (Terminal assignments are model number dependent.) MULTIPLE UNIT/REMOTE SETPOINT APPLICATION Eight T48 controllers are used in a drying oven. Each T48 controls a zone Whenever the master controller’s setpoint is changed, the slave controller’s within the oven. Depending upon the material to be dried, and its initial setpoint changes automatically. moisture content, the drying setpoint temperature varies. A master T48 The remote setpoint input at each slave controller can be scaled controller transmits setpoint via linear DC output. This signal is received as independently. a remote setpoint signal by the other slave controllers. (Terminal assignments are model number dependent.) 7 ORDERING INFORMATION Options and Output Boards are factory configured per the part number specified.
