The SNAP-RCK-M2B is a small adapter for SNAP B-series racks, which allows the rack to accommodate one SNAP PAC R-series controller or one SNAP PAC brain.

This rack adapter is useful for customers with existing B-series racks who need to replace an older I/O processor (such as a SNAP Ultimate controller or a SNAP Ethernet brain) with a SNAP PAC controller or brain. The adapter adds 0.675 inches (1.715 cm) to the overall height of the unit.

NOTE: The adapter does not change the module position limitations of the rack; 4-channel digital modules can still be placed only in the first eight positions on the rack.
