The ProSoft MVI56-GSC is a General Serial Communication module designed for Allen-Bradley ControlLogix systems, providing two configurable ASCII ports to expand serial connectivity without using processor resources. Installed in a single 1756 backplane slot, it enables seamless integration of external serial devices while freeing the processor’s main port for other applications. Operating at 800 mA @ 5 VDC and 3 mA @ 24 VDC, it performs reliably in environments from 32°F to 140°F, delivering durable performance in industrial automation systems.
