CAN Relay Box

1.​047.3xx.xxE ( choose order option )

The CAN Relay Box is the appropriate product when you want to determine potential-free, switching output signals that must be connected. You can set the signal potential yourself and individually for your application. The 12 potential-free relays can be activated using CAN messages. The module can be integrated into your network as a separate PLC or as a simple I/O module.

The box is very compact and thus space-saving, but still very versatile because relays and control functions are integrated into one device. This reduces the wiring outlay in your application.
