The TC‑001‑02‑2M5 is a chassis power cable designed to deliver 24 V DC power from a power distribution unit (such as the Triconex/Trusted Power Distribution

Unit or MCB) to a controller chassis or expander chassis within a Triconex/ICS Triplex safety control system. It is part of the TC‑001 family of

power interconnect cables used inside safety instrumented system (SIS) racks to ensure correct and reliable power

distribution among redundant modules.

Q: What exactly is the TC‑001‑02‑2M5 cable?

A: It’s a power connection cable used in Triconex/Trusted SIS racks to carry 24 V DC from a power distribution unit (e.g., MCB or power module) to

a controller or expander chassis inside the safety control cabinet. This ensures redundant and stable DC power distribution.

Q: What does “2M5” mean in the part number?

A: The suffix 2M5 denotes a 2.5‑meter cable length — a typical option in the TC‑001 power cable series for second or additional chassis

 connections in a rack. Shorter (e.g., 1.5 m) or longer (e.g., 6.0 m) lengths are available for different configurations.

Q: Where is this cable installed in the system?

A: It is mounted inside the Triconex/Trusted cabinet, connecting the power distribution unit (which establishes the

 24 V DC bus) to the trusted controller chassis or one of its expander chassis.
