4 Channel Relay Module 5 A – 230 VAC Type 1

The relays can be configured in the COMbricks web server (Output Control menu) to respond directly to bus problems like; bus voltage too low, master lost, and retries. This offers great applications to directly and independently act on the machine/process when bus communication becomes unreliable. Especially when the safety of human lives or the environment comes first.

Power switches, hold switches, indicators, backup systems, device I/O, doors, and LED towers are examples of machine parts that can be hooked up to the relays. The configured settings are saved and activated after reset or power-up.
