A system procurement specification identifies TC-201-01-6M5 as the 6.5 m version of the same I/O cable family and describes it as an internal 40-channel input connection to the FTA. This supports treating the 4M5 designation as the shorter 4.5 m configuration, while the exact connector and pin assignment should be confirmed against the applicable Trusted documentation before installation.
Product Introduction
The ICS TRIPLEX TC-201-01-4M5 is part of the Trusted system’s internal I/O cable family. Its role is to provide the physical signal connection between Trusted I/O hardware and the associated field termination arrangement. Unlike a T8110 processor or T84xx I/O module, this part contains no control logic of its own; system operation depends on the correct cable type, connector arrangement, wiring, and installed I/O architecture.
The 4M5 configuration is intended for installations where the required internal cable route is approximately 4.5 m. Cable length is not a cosmetic variation in a safety-system cabinet: excessive slack, insufficient reach, incorrect routing, or the wrong cable variant can create installation and maintenance problems.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
The TC-201-01 family is encountered in Trusted TMR I/O installations, where internal cabinet wiring connects I/O hardware with field termination equipment. A procurement team should therefore treat the cable as a system-specific spare rather than a generic multicore cable.
Typical Applications
- Trusted I/O cabinet wiring — connects the I/O side of the Trusted architecture with the applicable field termination assembly.
- 40-channel I/O installations — the TC-201-01 family is associated with 40-channel Trusted I/O wiring.
- Control-system maintenance — replacement of damaged, aged, or mechanically compromised internal I/O cabling.
- Legacy Trusted system support — useful when maintaining an installed Trusted architecture without redesigning the cabinet wiring.
Field Pitfalls
Do not buy by length alone. 4M5 describes the cable-length configuration, but the TC-201-01 family designation determines the intended system function. A similarly sized Trusted cable can have a completely different pinout or endpoint.
Do not confuse TC-201-01 with TC-202-01 or TC-206-01. System procurement documentation distinguishes TC-201-01 as an internal 40-channel input-side cable and TC-202-01 / TC-206-01 as different output-side cable configurations. They should not be substituted merely because the connectors appear similar.
Verify the complete assembly before shutdown work. For a live plant replacement, confirm the cable label, endpoint hardware, cable length, connector keying, and pin assignment against the installed Trusted system drawings. A wiring mismatch can present as an I/O fault rather than an obvious cable problem.

Procurement Note
For TC-201-01-4M5, the important procurement checks are TC-201-01 family designation, 4.5 m length, 40-channel I/O application, connector configuration, and the exact Trusted I/O/FTA hardware being connected.
I would reject listings that describe this part as a CPU, controller, 220 VAC module, or generic triple-redundant I/O card. Those descriptions are not consistent with the system-level identification available for the TC-201-01 cable family.
For a replacement cable, the safest method is to match the complete part number and physical connector arrangement against the existing installation. Do not assume that another TC-series cable with the same approximate length is interchangeable.
