This product is listed to provide access to its documentation.
The PCM-IO48 is a low cost, general purpose, PC/104 compatible 48-line parallel I/O controller based upon two 82C55A integrated circuits. The I/O lines are organized as two groups of three, 8-bit I/O ports. It is wired to two, 50-pin connectors which each will interface directly to industry standard 4, 8, 16 and 24-I/O module solid state relay mounting racks (Opto-22, etc.).
