An input/output module for implementing directions from a controller for sending and receiving signals to and from devices. The input/output module includes a microprocessor for communication with, and receiving programming from the controller. The input/output module further includes device communication connectors, each having number of pins, each pin for interconnection with a cable conductor to a device. The input/output module has an ASIC for each of the pins, providing a controlled interface with the corresponding pin. Each ASIC has interconnection apparatus, selectable by the microprocessor for providing a particular interface with the pin served by the ASIC.
