In-panel Temperature Controller with Flexible Modular Design and Wide Integration with Host Devices.

Radically Increase the Performance of Multipoint Temperature Control.

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.
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.

EJ1 Version 1.2

Reduce Design Work

HFU Ver. UP

The capacity of the area for programless communications with PLCs has been increased from 600 (version 1.1) to 1,200 parameters. You can now use more parameters for each loop or to support multipoint control.

Programless communications enables exchanging data simply by setting PLC flag operation and the EJ1 parameters. There is no need for creating a communications program. This results in a significant reduction in design work.

The HFU automatically performs communications with the PLC.

HFU Ver. UP

Operation commands that were previously executed for each channel can now be executed using bit specifications, reducing the amount of work required to create ladder programs.

Programless communications

Connectivity and Compatibility
Screen templates for the EJ1 are a standard feature in the NP-series PTs. There is no need to create basic screens, such as for monitoring the process value, the set point, or the manipulated variable.

Greater Connectivity and Compatibility

Examples of Standard Screens

Monitoring the Process Value (PV), Set Point (SP), or Manipulated Variable (MV)
Displaying the status during RUN, STOP, Manual Mode, or AT operation
Displaying the status of the two alarms using lamps
RUN/STOP and AT Execute/Cancel operations for each channel

Easy Installation and Setup

CX-Thermo Ver.UP

The CX-Thermo Support Software (version 4.1) supports multi-node settings to eliminate the need to change cable connections. It can be easily connected to any EJ1 Controller in a multi-node network.

Change nodes from the window.

Temperature Controller Ver.UP

A switch can be set to enable monitoring the output status on the operation indicators. The output status when a device is starting can be checked without using any special software. The communications baud rate settings and protocol changes for Modbus can also be set on a DIP switch.

Switch Setting for Monitoring the Output Status on the Operation Indicators.

Note:

Pin 6 of switch 2 can be turned ON or OFF while the power is ON. Normally keep this pin set to OFF so that operation status can be checked.

Flexible Control and Adjustments

Temperature Controller Ver.UP

Independent heating/cooling PID control (see note) and autotuning (AT) for heating/cooling are provided for devices such as extruders.

Independent heating and cooling PID control

Note: This control method allows independently setting PID control for heating and cooling.

Temperature Controller Ver.UP

Self-tuning (ST) (see note) can be used when AT is difficult to use to control devices with a large heating capacity.

Basic Functions

Smaller Control Panels
The EJ1 is the same size as PLCs to eliminate dead space.

Same size as PLCs with height of 90 mm. 70% of previous model.

Reduces Customer Inventory
Fully universal inputs for all input points to reduce inventory.

Easy model selection and reduced inventory.

Easy Installation and Wiring
Easy operation with one-touch terminal block attachment and removal and screw-less clamp terminals.

An M3-screw terminal block and screwless clamp terminal block cannot be interchangeable. Leave the wiring attached: Easy attachment and removal; Fewer wiring mistakes

Reliable Basic Functions and Quality
Operates at ambient temperature up to 55°C! UL, CE, and RoHS compliant.

Operates at -10 to 55°C

System Configuration

System with High Function Unit (HFU)
