HITACHI LPD350A Output Module

Technical Specifications

• Functions as a digital input processing or communication driver component within Hitachi control systems.
• Utilizes a modular layout to interface with controller logic backplanes.
• Implements multi-channel transceivers to manage logic routing between processors and peripheral lines.
• Fits single-slot dimensions within Hitachi racks, drawing current from the system power bus.

The LPD350A module functions as a data flow node between field signals and the internal core control unit, establishing a connection path between the underlying hardware and the system main control board to ensure correct interaction of control states and feedback data. The electrical circuitry incorporates industrial-grade anti-interference technology and signal isolation to block external high-frequency noise and transient electromagnetic interference from long-distance wiring, maintaining the stability of the controller's internal backplane logic bus. The front panel includes status indicators for field personnel to verify channel connection and communication status directly.

Lifecycle and Market Status

The LPD350A is deployed in centralized control networks or distributed control systems (DCS) of power plants, chemical plants, and large manufacturing facilities. The model has been discontinued from standard production by Hitachi and currently circulates in the global industrial automation market as a discontinued spare part for hardware replacement and routine maintenance of existing legacy control units.

Technical FAQ

Q: How to use products like the LPD350A?
