Fanuc IC655MDL512 PLC

This module provides 32 circuits for connection to user input devices. 32 LEDs on the front of the module 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, these LEDs provide the starting I/O address for the module. Field wiring connections to each circuit are made to the removable terminal block on the front of the module. Input circuits are divided into four groups, with 8 circuits in each group, The groups are labeled A, B, C, and D, and the input 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 source of power, which can be 12 to 24 VAC or 12 to 24 VDC, to sense the state of the inputs to the module.

Each group of inputs can be powered from a separate power source or a single power source can be used to Dower all groutx of inDuts.
