Resistive (heaters) or Inductive (transformers/motors).

Thermal cycling (heating and cooling) can loosen screw terminals over time.

This guide serves as a technical supplement to the official GMR32B manual, focusing on setup, wiring, and resolving heat-related issues. 1. Core Specifications & Setup

The GMR32B must be mounted on a properly sized heatsink. Between the backplate of the controller and the heatsink, you must apply a thin, even layer of . Without it, an air gap acts as an insulator, trapping heat inside the SCRs. B. Inadequate Airflow

Most digital variants of the GMR series feature LED indicators for thermal protection:

To prevent "hot" failures and extend the life of your controller, follow this quarterly routine:

Typically 4-20mA, 0-10V DC, or Potentiometer.

Dust buildup on the heatsink is a silent killer.
