Fanuc IC655MDL581 PLC

This module provides 32 normally-open relay circuits for controlling user output loads. The output switching capacity of this module is two amps, resistive load. The top 16 LEDs on the front of the module provide a dual function. 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. And when commanded through programmin g, 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 of eight. On the terminal block, they are labeled A, B, C, and D, with each terminal in the group labeled 1 to 8. Each group of eight has a single common connection, labeled H. This terminal serves as the hot terminal for AC loads or the common terminal for DC loads. The user must supply the AC or DC source of power for the loads connected to the module’s output circuits, and 24 VDC to power the module’s output circuitry.
