Installation and Maintenance
Mount the module on a standard DIN rail in a clean, dry control cabinet with proper ventilation. Ensure stable 24 V DC power supply before connecting bus and field wiring. Follow the wiring diagram to connect each output channel to corresponding actuators or instruments. Regularly check LED indicators to monitor channel status and system communication. Conduct quarterly inspections to verify terminal connections and clean dust from ventilation grilles. Only certified technicians should perform module replacement or configuration changes to maintain system integrity and safety compliance.
