Danfoss MCB 108MCB 108 Safe PLC Interface

The FC 302 provides a safety input based on a single pole 24 V DC input.

For the majority of applications this input enables the user to implement afety in a cost effective way.  For applications that work with mroe advanced products like Safety PLC, Lightcurtains etc, the new Safe PLC interface engables the connection of a two wire safety link.

The Safe PLC interface allows the Safe PLC to interrupt on the plus or the minus link without interfering the sensor signal of the Safe PLC.
