Honeywell 51305742-100 Shielded Twisted Pair Cable

Overview

The Honeywell 51305742-100 is a factory-engineered shielded twisted pair (STP) cable assembly used in Honeywell distributed control systems. It provides a stable and interference-resistant signal path between Honeywell I/O modules and their corresponding termination assemblies, including IOTA and IOM hardware.

Designed for legacy and long-life Honeywell platforms, this cable assembly ensures reliable transmission of both low-level analog and discrete digital signals inside electrically noisy control cabinets.

System Compatibility

The Honeywell 51305742-100 cable assembly is validated for use with the following Honeywell control platforms:

• Honeywell TDC 3000

• Honeywell TPS (TotalPlant Solution)

• Experion systems utilizing classic I/O architectures

It is intended for direct replacement of original Honeywell I/O interconnection cables without modification.
