Product Information

Product Description

Authorized North America Distributor Stamp

The ComBricks Standard 4 channel relay module with normally Open and normally Closed connectors allows you to build up a ComBricks system to respond to network events, or to create PROFINET remote I/O systems. The module’s relays can also be controlled manually or by a timer through the web server (Output Control menu). In addition, the module will be able to be used in the future to create PROFIBUS DP slaves with I/O. The relays are 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 such as: bus voltage too low, master lost and retries. This unique feature allows applications to directly and independently act on the machine / process when the bus communication becomes unreliable. This is especially important when there are environmental or human safety impacts when a system goes down.

Examples of devices that can be hooked up to the relays:

  • Power switches
  • Hold switches
  • Indicators
  • Backup systems
  • Device I/O
  • Doors
  • LED towers

The configured settings are saved and activated after reset or power-up.
