Acromag AVME9470 Digital PCB Card

Acromag AVME9470 is a VMEbus digital I/O board that provides 80 programmable I/O points on a single card, part of the AVME947x family designed to expand front-panel I/O in industrial control systems. Each point can be configured as an input or output, enabling flexible mapping of digital signals across a single module. The AVME9470 (and AVME9471) uses front cable access for its 80 I/O lines, while the AVME9475 variant provides 40 I/O points via rear cable access (P2). The inputs operate from 0 to 5 V DC, with typical input thresholds around 0.8 V for a high and 2.0 V for a low, making the board compatible with TTL/CMOS logic levels. A part number associated with this digital PCB card is 1018-510A. Note that multiple sources indicate the AVME9470 has been discontinued by the manufacturer, so sourcing may rely on used or refurbished units.
