Honeywell 51304584-300 Digital Input Module | 32-Channel DI

Honeywell 51304584-300 Digital Input Module

The Honeywell 51304584-300 Digital Input Module provides stable and reliable signal acquisition for plants using Experion PKS Series-A I/O, TPS, and TDC 3000 control systems. It captures discrete field signals such as ON/OFF states, open/closed positions, and alarm conditions with consistent accuracy. Moreover, its rugged electronic design ensures dependable operation in industrial environments exposed to vibration, temperature swings, and electrical noise.

This module integrates smoothly with existing Honeywell architectures, which helps extend the lifecycle of legacy installations. In addition, its built-in diagnostics assist engineers during commissioning and troubleshooting because abnormal channel conditions are quickly detected through onboard indicators. Therefore, the 51304584-300 supports both modernization projects and long-term maintenance plans across critical process facilities.
