Fanuc IC655MDL555 PLC

This module provides 16 circuits for controlling user output loads. The output switching capacity of this module is two amps. 16 LEDs on the front of the module provide a dual function. First, they provide a visual indication of the status of each output circuit, with each LED reflecting the ON or OFF state of the corresponding circuit. Second, when commanded through programming, they indicate 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 output circuits are divided into four groups internally. On the terminal block, the groups are combined and are labeled A and B, with 8 circuits in each group. The terminals in each group are labeled 1 to 8. Each group of eight has a single common connection, labeled C. The user must supply a 24 VDC source of power, which provides power for both the load and the output circuit. Both groups can be powered from a single power source or each group can be powered from a separate source.
