Ampro CM2-4DI-Q-74 4 Channel Digital Input Module

AMPRO CM2-4DI-Q-74 is a PC/104-compatible four-channel digital input module in the Ampro CM2 CoreModule family. It provides four digital input channels that interface with a CM2/PC-104 host for sensing external signals in industrial control and automation applications. The module carries the part number 069-00007-0001 REV A, a designation used by distributors and service providers to identify this exact model. In marketplace listings the CM2-4DI-Q-74 is frequently described as refurbished, with services such as diagnostic evaluation, component repair, and rebuilding offered by third-party refurbishers, reflecting common availability. As part of the CM2 ecosystem, this I/O board expands a CM2 system’s input capability without adding separate PLC hardware, enabling direct digital signal acquisition from sensors, switches, or limit devices into the CM2 CPU environment. This combination of four inputs and CM2 compatibility makes it suitable for small- to mid-size embedded automation tasks where a compact PC/104 I/O expansion is desirable.
