Modular Temperature Controller EJ1 CSM EJ1 DS E 12 5 In-panel Temperature Controller with Flexible Modular Design and Wide Integration with Host Devices The compact modular structure enables construction of temperature systems optimally suited to the application. Connection can be made to a Programmable Controller without any programming required, reducing the number of steps required in ladder programming design. One fully universal-input Unit includes a thermocouple, platinum-resistance thermometer, and analog input for easy selection and reduced inventory requirements. Connect directly to the G3ZA Multi-channel Power Controller using optimum cycle control for high-accuracy regulation with minimal noise. Supports DeviceNet Communications. Autotuning (AT) can be used for independent heating/cooling PID control. Self-tuning (ST) can be used to calculate the PID constants with the step Refer to the Safety Precautions on response method. page 20. Up to 16 Temperature Controllers can be connected to a single DeviceNet Communications Unit.

An End Unit is always required for connection to a Basic Unit or an HFU. An HFU cannot operate without a Basic Unit. External communications cannot be performed when using a Basic Unit only. *2. For heating/cooling control applications, control outputs 3 and 4 on the 2-point models are used for the cooling or heating control outputs. On the 4-point models, heating/cooling control is performed for the two input points. *3. When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately. Note: Products for the EtherCAT master are also available. Ask your OMRON sales representative for details. Functional Upgrades Refer to page 17 for details.
