HHM1 Series counting relays are panel counters for forward or reverse pulse counting from contact signals, meter wheels and PNP photoelectric or proximity sensors. The models share the same supply, input and relay-output platform, while differing by counting range, speed, coefficient setting, output mode and front size.
