The I/O IC600CB503 (Input/Output) Control module is utilized in the Series Six Central Processing Unit (CPU) to provide an interface between the CPU and the primary I/O chain; it also controls data transfers between the CPU and peripheral devices such as the Program Development Terminal (PDT) and the Data Processor Unit (DPU).

The module provides four Light-Emitting Diodes (LED's), visible through a lens on the faceplate, which indicate I/O-chain parity and continuity conditions, whether user I/O are enabled, and problems with the DPU interface. The LEDs operate only when the module is installed in a properly powered CPU rack.

Two, 37-pin "D" type connectors are available for cable connections. One, marked "I/O", can be used for linking an I/O Receiver module up to 50 feet away; the other connector, marked "PP/DPU", can be used to connect a cable from the DPU or the PDT.
