EJ1 Modular Temperature Controllers

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.

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.

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.

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.

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.

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.

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.

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

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

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

System Configuration

System with High Function Unit (HFU)

Programless Communications for 1,024-channel Systems

Build 200-channel Systems with DeviceNet Communications

Applications

Electric Component Furnaces

The EJ1 can control up to 1,024 channels with programless communications. Monitoring of multipoint heater temperatures and integrated processing with high-precision controls are easy for continuous furnaces to create a system without waste.

Molding Machines

Independently set heating/cooling PID control improves control of molding machines.
OMRON's unique optimum cycle control improves the power factor and reduces energy consumption.
