CJ Series Temperature Control Unit CJ1W-TC CSM CJ1W-TC DS E 2 1 A Single Unit Performing All the Functions of 4 Temperature Controllers A Special I/O Unit with direct input of thermocouple or resistance thermometer, PID control with 2 degrees of freedom, and open collector output CJ1W-TC001 Features Built-in PID control with 2 or 4 control loops or ON/OFF control Direct input of 7 types of thermocouple or resistance thermometer 500 ms sampling cycle RUN/STOP control from CPU Unit Unrestricted CPU Unit cycle time Heater burnout detection Auto-tuning (AT) function 1O N 1 2 3 4 5 6 7 8 CJ1W-TC System Configuration The following diagram shows a basic system with a CJ1W-TC001 Temperature Control Unit (4 control loops, thermocouple inputs, and NPN outputs) and a CJ1W-TC103 Temperature Control Unit (2 control loops with heater burnout detection, platinum resistance thermometer inputs, and NPN outputs). Note that this system configuration is given strictly as an example. When constructing an actual system, check the specifications, performance, and safety of each component by referring to the respective manuals. CJ1W-TC001 Four-loop Unit, CJ1W-TC103 Thermocouple, Two-loop Unit, HB alarm, platinum NPN outputs resistance thermometer, NPN outputs Power supply for outputs (24 VDC) Control output Heater 1 kW Temperature Sensor Current 200 VAC Transformer Thermocouple or platinum resistance thermometer E54-CT1 or E54-CT3 Note: 1. An OMRON E54-CT1 or E54-CT3 Current Transformer must be used as the Current Transformer (CT). Do not use any other Current Transformer. 2. Turn ON the Stop Bit for the loop to stop temperature control. If PID control is being used and the heater is turned OFF using an operation switch input to the heater, PID control performance will be adversely affected. 3. To connect this Unit to the NJ series, set pin 3Data storage/display forma of the DIP switch to ON. (The factory setting is OFF) SW3 Data storage/display format Settings Settings are not allowed. OFF 16-bit binary ON MODE This change becomes effective when the Controller is reset, or when the Unit is restarted. 2
