5. Application Scenarios and Safe Operation Precautions
5.1 Application Scenarios
- Power Generation Industry: Switch status monitoring of substation auxiliary systems, start/stop control of fans/water pumps, ensuring the stable operation of auxiliary equipment.
- Metallurgical Industry: Valve switch control and actuator driving in small steel rolling production lines, meeting the requirements of discrete process control.
- Light Industry: Equipment start/stop control in food and pharmaceutical production lines, switch status monitoring of packaging machinery, adapting to the automation control requirements of small and medium-sized installations.
5.2 Safe Operation and Maintenance Specifications
- Installation and wiring must be performed by professional personnel. Before operation, disconnect the system power supply and load circuit, and confirm no voltage exists before disassembly and assembly to avoid electric shock or module damage.
- DI/DO wiring must match terminal specifications; shielded cables should be used with the shielding layer grounded at a single point to prevent signal distortion caused by interference.
- Regularly check the module temperature, terminal tightness and channel status. In case of channel faults, replace the module in a timely manner and troubleshoot load faults.
