IEMMU21

Module Mounting Unit, (Rear Mounted)

The Module Mounting Unit provides the housing, power connections and communications support for all the modules. Its backplane contains the Module Bus, on which master modules communicate with each other and the Slave Expander Bus, on which the master module talks to its I/O slaves. The IEMMU21 is used when the cabinet configuration requires a rear-mount chassis with no primary power distribution.
