Modular Temperature Controller
EJ1
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.
• Autotuning (AT) can be used for independent heating/cooling PID control,
and self-tuning (ST) can be used to calculate the PID constants with the step
response method.
• Up to 16 Temperature Controllers can be connected to a single DeviceNet
Communications Unit.

Note:
1. 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.
Functional Upgrades
