Product Description

The HITACHI LYA010A is a dedicated high-precision analog input module developed for Hitachi industrial PLC and DCS automation systems. Serving as a core field signal acquisition unit, it specializes in collecting industrial analog parameters such as pressure, temperature, flow and liquid level, converting weak field sensor signals into standard digital data for system logic analysis and closed-loop process control.

Adopting high-resolution sampling chip and multi-stage EMI filtering technology, this module achieves ±0.1% full-scale acquisition accuracy and ≤1ms ultra-fast response speed. It features full-channel optocoupler isolation and complete surge protection design, effectively suppressing industrial electromagnetic noise and signal distortion. With wide-temperature environmental adaptability and low-power stable operation, it supports 24/7 long-term high-precision monitoring in harsh industrial production scenarios.
