Honeywell HPK2-3 51401583-100 Enhanced Process Network Interface Board

Honeywell HPK2-3 51401583-100 Enhanced Process Network Interface Board

The Honeywell HPK2-3 51401583-100 Enhanced Process Network Interface (EPNI) board is a key logic component used within Network Interface Modules (NIMs) in Honeywell TDC 3000 Distributed Control Systems. It supports communication between control networks used in industrial automation architectures.

Network Interface Function

• Acts as the main logic board within a Network Interface Module (NIM)
• Facilitates communication between the Universal Control Network (UCN) and Local Control Network (LCN)
• Supports data exchange between control devices and system nodes

System Architecture Role

The EPNI board operates as part of a modular NIM node alongside K4LCN processors and I/O cards. This architecture supports structured network communication within Honeywell TDC 3000 control systems deployed in industrial environments.

Typical Applications

• Distributed process control systems
• Industrial automation network infrastructure
• Legacy Honeywell TDC 3000 system installations
