Working Principle
Field switch signals are connected through terminals, transmitted to internal drive circuit after conditioning; the drive circuit controls the relay to act, and the relay contacts output switch signals to control field loads. The module completes signal access, drive and output in one unit.
Advantage Highlights
- Integrated design, reduce intermediate wiring links
- Small size, high space utilization
- Independent channel protection, high operation safety
- Simple installation and maintenance
Applicable Industries
Industrial auxiliary equipment control, small switch load drive, on-site signal collection and control, factory auxiliary automation
Installation Requirements
- Rack installation in standard control cabinet
- Load wiring strictly follow rated contact parameters
- Ensure good heat dissipation around the module
Usage Notes
- Do not overload relay contacts
- Reduce frequent switching of inductive loads
- Regularly check terminal and contact wear
- Use in non-corrosive and dry environment only
