Product details

Compatibility and fit in the S7-300 chassis

The 6ES7181-0AA00-0XA0: The IM 181 carrier board is designed for the S7-300 DIN-rail mounting system — it snaps onto the standard profile rail and occupies one slot width in the rack. The board routes the backplane signals to the IM 180, which then provides the interface to expansion racks or remote I/O. Because it is a passive carrier, the compatibility is defined by the IM 180 module it supports; the carrier itself mates with any S7-300 backplane that accepts the standard 40-pin connector.

Frequently asked questions
