Hitachi LYD105A High-Density Digital Output Module (24VDC, Modbus RTU, Industrial-Grade)
Product Description
The Hitachi LYD105A is a rugged, high-density digital output module engineered for Hitachi DCS/PLC industrial automation systems, designed to deliver reliable control signals to actuators, valves, contactors, relays, and other field devices in harsh industrial environments. Featuring 24 VDC redundant power input, Modbus RTU (RS-485) communication for seamless integration, and industrial-grade EMI/RFI shielding, this modular I/O component supports dry contact/voltage digital outputs with high-current capacity per channel and compact rack-mount form factor. With IP20 front-panel protection, wide temperature operation (-20°C to +70°C), and hot-swappable design for minimal downtime, it is certified for process control applications in power generation, chemical processing, oil & gas, and manufacturing industries, delivering stable performance for critical equipment control and safety interlock systems.
Key Functions
The LYD105A delivers mission-critical digital output control with these core features: High-density digital output channels for driving multiple industrial actuators and valves simultaneously; 24 VDC rated output with robust overcurrent/short-circuit protection per channel; Modbus RTU communication protocol for easy integration with PLCs, DCS, SCADA systems, and HMI panels; 24 VDC redundant power input with low current consumption for reliable operation; Hot-swappable modular design for maintenance without system shutdown; Industrial-grade EMI/RFI shielding and IP20 protection for harsh plant environments; Wide temperature range operation (-20°C to +70°C) for global industrial deployments.
Application Scenarios
The Hitachi LYD105A is optimized for digital output control in industrial automation applications including: Process control in chemical plants, refineries, and LNG terminals requiring high-density actuation; Power generation turbine/boiler control systems with multiple safety shutdown and isolation valve outputs; Oil & gas upstream/midstream process skids with emergency shutdown and flow control valve outputs; Manufacturing automation lines with high-density motor starter and conveyor control; Retrofit solutions for legacy DCS/PLC systems needing digital output expansion; Distributed I/O networks in remote monitoring stations with Modbus RTU communication.
