Process Control Solution – HITACHI LYA220A AI Communication Board | EX Series DCS
The HITACHI LYA220A is an Analog Input (AI) Communication Board designed for HITACHI’s EX Series Distributed Control System (DCS). Built for demanding industrial environments, this module delivers reliable, high-accuracy analog signal acquisition and transmission across process control networks. Engineers specify the LYA220A where signal integrity, system compatibility, and long-term availability are non-negotiable.
Where This Product Is Used
The HITACHI LYA220A AI Communication Board is deployed across a wide range of process-critical industries and applications:
- Oil & Gas Refineries — Analog signal acquisition from pressure transmitters, flow meters, and temperature sensors in upstream and downstream processes.
- Chemical & Petrochemical Plants — Continuous monitoring of reactor parameters, tank levels, and heat exchanger performance via 4–20 mA field instruments.
- Power Generation — Integration with turbine control systems and boiler management for real-time analog feedback loops.
- Water & Wastewater Treatment — pH, dissolved oxygen, and flow rate monitoring in SCADA-linked DCS architectures.
