Dison Technology AMC167 Rev A 8-Bit ISA Port Controller Card 40-Pin Internal

Dison Technology AMC167 Rev A 8-Bit ISA Port Controller Card 40-Pin Internal 37-Pin

The Dison Technology AMC167 Rev A is an 8-bit ISA expansion card designed as a port controller for interfacing a host computer to external peripheral or automation hardware. The PCB silkscreen reads PWB AMC167 REV A / CCA AMC168 REV / Copyright 1995 Dison Technology, and the card most likely serves as the computer interface controller for a Dison Clippard Multi-Port Manifold system. It features a 40-pin internal header and a 37-pin D-sub external connector mounted on the ISA bracket, with a red DIP switch bank for configuration.

Applications

8-bit ISA controller cards of this type were used in the mid-1990s to bridge a PC's ISA bus to external automation, pneumatic control, or multi-port peripheral systems. The 37-pin D-sub external connector and 40-pin internal header are typical of cards that connected a computer to manifold valve arrays, relay banks, or multi-channel I/O breakout hardware. Clippard Instrument Laboratory is a well-known manufacturer of pneumatic and electronic control components, and multi-port manifold controllers of this era were commonly used in laboratory automation, fluid dispensing, and light industrial process control. The 8-bit ISA bus was the standard expansion interface in IBM PC/XT and early AT-class computers, remaining in use well into the mid-1990s in industrial and embedded control applications where ISA slots were still common on industrial single-board computers and embedded PCs. Systems integrators maintaining legacy Dison/Clippard manifold setups, or builders of ISA-bus industrial control platforms, are the most likely buyers for this card.
