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.

Is there a terminating resistor on the CAN relay box?

Yes, the DIP switch on the board must be set to ON for this.
For more information, please contact our support.

What is the quiescent current of the CAN relay box?

The quiescent current is:
12 V => 0.21 mA
24 V => 0.50 mA

Is the CAN relay box CAN wake-up capable?

Yes, the CAN wake-up functionality can be set via the DIP switches (R131 switch 1).
