OVERVIEW
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 where each will interface directly to industry standard 4, 8, 16 and 24-I/O module
solid state relay mounting racks (Opto-22, etc.).
The PCM-IO48 is small, only 3.6" x 3.8". It is an 8-bit, stackthrough module that can be used in a
standalone stack or as a mezzanine bus stacked atop a larger single board computer like the WinSystems’ EBC, LBC PCM, and
SAT series of embedded PCs. It will operate over the full industrial temperature range of -40°C to +85°C.
