Fanuc IC655MDL501 PLC

This module provides 16 circuits for connection to user input devices. 16 LEDs on the front of the module provide a dual function. They provide a visual indication of the status of each circuit, with each LED reflecting the ON or OFF state of the corresponding circuit. When commanded through programming, they provide the starting I/O address for the module. Connections to each circuit are made to the removable terminal block on the front of the module. The input circuits are divided into two groups, A and B, with the input terminals for each group labeled 1 to 8. Each group has a single common connection, labeled C, for the eight circuits in the group. The user must supply a 12 to 24 VDC source of power for sensing the state of the inputs to the module. Both groups can be powered from a single power source or each group can be powered from a separate source.
