HITACHI LPP100A Pulse Input Module

Technical Specifications

• Receives high-speed pulse signals from field sensors
• Converts external frequency and pulse physical signals into digital data for the core controller
• Pairs with terminal boards (such as TT000A) in a modular plug-and-play structure to allow replacement without rewiring
• Includes industrial electromagnetic compatibility (EMC) and noise isolation circuitry to maintain signal integrity during field communications

The LPP100A functions as a node for network and data exchange within the system, establishing a data path between the core control unit and the field bus to synchronize control instructions and feedback signals. The electrical structure integrates isolation elements to block electromagnetic noise from high-power field equipment from reaching the core logic backplane of the controller. The panel features status indicators to verify the operational state and communication data link of the module.

Lifecycle and Market Status

The LPP100A functions within control networks of power plants, chemical lines, and manufacturing facilities to maintain data transmission continuity. Volume production of this model has ceased. The hardware circulates as a replacement component within global surplus and reconditioned material markets to support component swapping during hardware failures or repairs in legacy control units.

Technical FAQ

Q: How to use products like the LPP100A?
A: Install the module onto the system rack bus, connect cables from the external field bus and the core control unit, and establish the data path through system configuration.

Q: Between which components does the LPP100A establish a data path?
