Working Principle
The control system sends digital control commands to the module via the bus. The internal drive circuit drives the corresponding relay to pull in or disconnect. The relay contacts output switch signals to control medium-power field loads. The module collects relay state and fault information and feeds back to the main controller in real time.
Advantage Highlights
- Medium load capacity, wide application range
- Full protection design, high operation safety
- Stable relay performance, long service life
- Real-time fault feedback, easy for operation and maintenance
Applicable Industries
Power plant auxiliary motor control, industrial valve switch control, medium-power actuator control, factory automation switch control
Installation Requirements
- Mount on standard 19-inch industrial control rack
- Load current and voltage shall not exceed relay rated values
- Reserve heat dissipation space around the module
Usage Notes
- Match absorption protection components for inductive loads
- Prohibit long-term overload operation
- Regularly check relay contact temperature and wear
- Replace with GE original modules only after failure
