PRODUCT INFORMATION
Product Overview
The Allen-Bradley MVI94-GSC-E is a FLEX I/O single port interface module. This unit mounts directly into a single slot of any standard 1794 backplane. It draws a low backplane current of 20 mA at 5 VDC during normal operation. An external power supply provides 12 to 24 VDC with current consumption between 170 and 340 mA.
The unit provides an RS-232 serial configuration port using a mini-DIN connector interface. It supports serial communication baud rates ranging from 110 to 115200 bauds. Configurable data bit options range from 5 to 8 bits for flexible serial communication. Integrated LED status indicators provide immediate visual diagnostics during system operation and routine maintenance.
