The Counting Relay HHJ1 Series is a panel-mounted counter range for machine counting, batch counting and sensor-based pulse counting. HHJ1 is a 4-digit positive counter, while HHJ1-B and HHJ1-F add 5-digit forward/backward counting, faster high-frequency input and extended output modes for more flexible control circuits.
