- Process control: Start-stop control of valves and pump stations in chemical, petroleum, metallurgical and other industries.
- Building automation: On-off control of lighting, air conditioning and access control systems.
- Energy management: Relay protection and monitoring in power plants and distribution networks.
6. Installation & Maintenance Guidelines
Installation
- Adopt DIN-rail side mounting or panel mounting, and ensure the fixing screws are tightened securely.
- Confirm the supply voltage is 24 V DC before wiring to avoid incorrect connection of high voltage.
- Keep ventilation around the module to prevent overheating.
Wiring
- Use the standard terminal block screws to ensure each wire is connected firmly without loosening.
- For high-current loads, parallel fuses or current-limiting resistors at the output terminal.
Commissioning
- Conduct channel mapping in PLC software and check the status indicator of each channel.
- Utilize the module’s built-in diagnostic function to confirm no short-circuit, open-circuit or overload alarms.
Daily Maintenance
- Regularly check the tightness of terminal blocks to prevent loosening caused by vibration.
- Remove dust and corrosives on the module surface to keep the heat sink well-ventilated.
- Replace the corresponding relay or the entire module in time if contact abnormalities (abnormal clicking sound, slow response) are found.
