4-Channel Relay Module 5 A – 230 VAC
Previous product Next product

Relay ModuleStandard 4-channel relay module with normally Open and normally Closed connectors. Can be controlled by the web server (Output Control menu), DP slave or PROFINET IO device. Suitable for 5 A – 230 VAC.

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 the bus communication becomes unreliable. Especially when 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.
