Application
In this example configuration, G3ZA Multi-channel Power Controllers are used
to control the temperature in a 4-zone heater plate with a single control loop
by applying a fixed coefficient (slope) to the results of the EJ1's PID calcula-
tions.
• Up to eight G3ZA Controllers can be connected to the EJ1
@
-TC4 using
the special communications ports. It is not necessary to create a program
for communications between the EJ1 and G3ZA.
• Also, the G3ZA's internal parameters can be set to split a single EJ1
channel's control output into 4 branches (with the G3ZA-4H
@
03-FLK) or 8
branches (with the G3ZA-8A
@
03-FLK).
• A slope (coefficient) and offset value can be set for each branch output.
