GE VMIVME2540 VME Intelligent Counter Controller Board in stock

GE VMIVME2540 (VMIVME-2540) is a 6U VMEbus intelligent counter controller module originally from VMIC/GE Fanuc, now Abaco Systems. It has 24 independent programmable counting channels, used for high-precision pulse counting, period measurement and pulse generation in VME-based industrial control systems, widely adopted in GE Mark VI turbine control platform.

The board integrates an on-board 68HC000 15MHz processor to handle counting tasks independently and reduce main CPU load. It supports TTL single-ended and RS-422 differential input with strong anti-interference capability. Widely used in power, chemical and pulp & paper turbine control maintenance, spare replacement and control system retrofit projects.
