OMRON Electronics has released a load cell interface for PLC, which mounts directly into any special I/O unit. The unit interfaces with the CPU at high speed, allowing the PLC to perform controlling functions while taking weight measurements. The load cell is designed to check weighing and batching applications, and supports up to four load cells connected in parallel using a single six-wire connection. Auto free fall compensation is standard, and the unit can be recalibrated for the effects of gravity, which change from location to location. The product features automatic compensation of temperature fluctuation and a low-pass bessel filter to counteract the effects of mechanical vibration.
