Invensys 4000056-002 I/O Bus Cable

Overview

The Invensys 4000056-002, also cataloged as the 4000056-002 I/O Bus Cable, operates as a dedicated hardware component for signal interconnection between Triconex system assemblies and I/O bus communication interfaces. It provides a physical cable path for internal data transmission within Invensys Triconex control platforms.

Hardware Specifications

Triconex TMR System Interconnection Characteristics

The 4000056-002 cable assembly provides electrical connectivity between Triconex system hardware modules through the dedicated I/O bus interface. Therefore, it maintains the required signal routing path for communication between control components.

The cable uses PVC insulation material for industrial wiring protection and supports an operating temperature range from -40 deg C to +70 deg C. In addition, the assembly design follows Triconex system installation requirements for internal cabinet connections.

For Triconex safety systems using triple modular redundancy (TMR) 2oo3 architecture, proper cable routing supports consistent signal transfer between redundant control paths. Furthermore, correct installation helps maintain galvanic separation requirements where applicable within the overall SIS cabinet design.

Frequently Asked Questions

Q: What is the primary function of the Invensys 4000056-002 cable assembly?
A: The 4000056-002 functions as an I/O Bus Cable that provides physical signal interconnection between compatible Triconex system components.

Q: Does the 4000056-002 require an external power supply?
