The Counting Relay HHM3 Series is a 72×72mm panel counter for high-speed reversible counting applications. HHM3-H accepts rotary encoder, meter-wheel and PNP sensor inputs, supports B/C reversible counting, reaches 5000 counts/sec in high-speed mode and retains count data for up to 10 years during power loss.
