The Omron K3HB series includes load cell input models, specifically the K3HB-V, which supports millivolt (mV) input from load cells. The available AC voltage supply options for these controllers include:

- 100-240 VAC (with 10 VDC ±5%, 100 mA sensor power supply)

These controllers are designed for weighing applications using load cells, supporting input signals such as millivolt outputs from load cells (e.g., 2 mV/V).
