Modular Temperature Controller for Gradient Temperature Control EJ1G 1

Modular Temperature Controller for Gradient Temperature Control

EJ1G

Gradient Temperature Control to Achieve
Consistent Layer Temperature

• Perform gradient temperature control ranging from 2 to 32
channels.

• Perform 2-channel gradient temperature control for up to 16
groups, or 32-channel gradient temperature control for up to 2
groups.

• Set gradient temperature control or 2-PID control for each
group.

• Reduce design work for ladder programming with programless
connections to Programmable Controllers. (The same feature
as Standard-control EJ1 Models.)

• Connect directly to the G3ZA Multi-channel Power Controller
using optimum cycle control for high-accuracy control with
minimal noise.

Refer to the “Safety Precautions” on page 18.

Ordering Information

■ Temperature Controllers

Gradient Temperature Control

Note: 1. An End Unit is required to connect an HFU to a Basic Unit. A Gradient Temperature Control HFU and a Gradient Temperature Control

Basic Unit must be used together to achieve gradient temperature control. The Gradient Temperature Control HFU and Gradient
Temperature Control Basic Unit are used exclusively for gradient temperature control, but the End Unit is the same as that used for the
Standard-control EJ1 Models.
The Basic Unit cannot communicate externally by itself.

2. Heating/cooling control is not supported for gradient temperature control.

3. When using the heater burnout alarm, use a Current Transformer (E54-CT1 or E54-CT3) (sold separately).
