Engineered for high-speed rotational measurement, the Omron K3HB-RNB-C2 serves as a highly precise digital rotary pulse indicator within demanding industrial automation frameworks. Designed to support rotary pulse inputs up to 50 kHz, this device provides instantaneous, high-resolution velocity and rotation metrics. The unit integrates an NPN/voltage pulse sensor input configuration and utilizes four independent SPST-NO relay outputs for critical limit monitoring (HH, H, L, LL). Its multi-color display dynamically changes color based on alarm status, providing field operators with immediate visual confirmation of system performance.

The K3HB series serves as the modern standard update to legacy Omron K3N indicators. While functional similarities exist, please note that wiring structures and rear terminal blocks differ significantly. Panel cutouts are standardized, but back-of-panel depth clearances must be verified during system retrofits to accommodate the output terminal configuration on the K3HB-RNB-C2.
When utilizing the maximum 50 kHz measurement range, standard sensor wiring is highly susceptible to electromagnetic interference (EMI). Run signal lines in independent, grounded steel conduits separate from high-current motor leads or Variable Frequency Drive (VFD) output cables to prevent false triggering. Keep the cable length to the sensor as short as possible to prevent signal attenuation.
Ensure that the internal parameter settings match the connected sensor type (NPN open-collector versus voltage pulse). Failing to configure this software parameter correctly may result in zero pulse registration or risk overloading the internal signal pull-up circuit. Always apply shielded twisted-pair (STP) cabling for the input connections.
Prepare a standardized 1/8 DIN panel cutout (92 mm x 45 mm) and slide the unit through the panel front, ensuring the rubber sealing gasket is flat against the surface.
Secure the unit into the panel using the provided side mounting fixtures, tightening the screws evenly to ensure a secure dust and water-resistant fit.
Attach the sensor input cables to the designated NB terminals using properly sized crimped ferrule connectors to ensure permanent gas-tight contacts.
Connect the 100 to 240 VAC power line to the primary power input terminals, re-check terminal polarity, and proceed to device parameter configuration.
