Hitachi LYA210A Precision Analog Input Module (4-20mA, Modbus RTU)

Product Description

The Hitachi LYA210A is a high-precision analog input module engineered for reliable 4-20mA current signal acquisition in industrial automation systems, including Hitachi DCS/PLC platforms. Designed to capture process data from transmitters, sensors, and field instruments in harsh industrial environments, this modular I/O component features 24 VDC redundant power input, MODBUS RTU communication for seamless integration, +/- 0.1% full-scale accuracy, and 250Ω load capacity per channel. With IP20 front-panel protection, wide temperature operation (-20°C to +70°C), and industrial-grade EMI/RFI shielding, it delivers stable performance for critical process control, monitoring, and data acquisition applications in power generation, chemical processing, oil & gas, and manufacturing industries.

Key Functions

The LYA210A delivers mission-critical analog signal acquisition with these core features: High-precision 4-20mA current input channels for real-time process data capture; MODBUS RTU protocol for easy integration with PLCs, DCS, SCADA systems, and HMI panels; +/- 0.1% F.S. accuracy (supplemental +/- 0.2% + 2LSB for enhanced precision) for critical measurement applications; 24 VDC power input with max. 50mA current consumption for low-power operation; 250Ω load capacity per channel to support standard industrial transmitters; Hot-swappable modular design for minimal downtime during maintenance/upgrade; IP20 protection and wide temperature range (-20°C to +70°C) for harsh industrial conditions.

Application Scenarios

The Hitachi LYA210A is optimized for analog signal acquisition in industrial control applications including: Process control systems in chemical plants, refineries, and LNG terminals; Power generation monitoring (boiler, turbine, generator parameter acquisition); Oil & gas upstream/midstream process monitoring (pressure, flow, level, temperature); Manufacturing automation (machine tool process control, quality inspection data acquisition); Retrofit solutions for legacy DCS/PLC systems requiring high-precision analog input expansion; Distributed I/O networks in remote monitoring stations with MODBUS RTU communication.
