Fanuc IC655MDL593 PLC

This module provides 64 circuits for controlling user output loads. 32 LEDs on the module indicate the status of the 32 Outputs associated with one connector. A toggle switch above the top (Jl) connector allows the user to choose the group of inputs being monitored (A to D, or E to H). The top 16 LEDs perform a dual function. They normally provide a visual indication of the status of each input circuit with each LED reflecting the ON or OFF state of the corresponding circuit. Second, when commanded through programmin g, they indicate the starting I/O address for the module.

Field wiring connections to output loads are made to two 37.pin subminiature D-type connectors (labeled Jl (A-D) and J2 (E-H)), mounted on the front of the module. One connector is used for two groups with 16 inputs in each group. The four groups are labeled A and B (group l), C and D (group 2), E and F (group 3), and group 4 is G and H. The pins in each group are labeled 1 to 8, for example: group 1 is Al to A8 and B 1 to B8. Each group has a common connection, labeled C. The user must connect a 5 to 12 VDC power supply to each group, which supplies both the load and the output circuits.

All groups can be powered from a common source or from different sources.
