51400901-100 Honeywell Processor LAN Interface Control Board

Product Description

The Honeywell 51400901-100 is an Enhanced Module Processor Unit (EMPU) designed for Honeywell TDC 3000 distributed control systems.
It combines processing power, local memory, and LAN communication on a single industrial-grade control board.
Moreover, this integrated design reduces system complexity while improving deterministic control performance.
Therefore, the module serves as a central processing element within node and panel-mounted configurations.
It is commonly used where reliable real-time execution and communication are required simultaneously.
