TRICONEX 4000212-020 – Field Termination Assembly for Tricon TMR Safety I/O

• Warranty: 365 days

• Delivery time: Typically 1 week for in‑stock items; no more than one month at the latest

• Payment terms: 50% advance payment; full payment prior to delivery

• Express options: FedEx, UPS, DHL

• Purpose‑built termination for Triconex I/O – Provides a clean landing point between field wiring and the associated Triconex module in TMR architectures.

• Structured channel labeling – Channel IDs and terminal markings typically mirror the I/O card, minimizing wiring errors and rework.

• Robust screw/clamp terminals – Secure connections for discrete or analog signals, helping maintain signal integrity in noisy industrial cabinets.

• Shield management – Grounding points and clear routing for shields reduce interference on low‑level signals in many cases.

• Cabinet‑friendly footprint – Usually fits comfortably on DIN rail or panel backplates, easing retrofits and expansions.

• Serviceable design – Access to terminals and cable headers is straightforward, which makes loop checks and maintenance quicker.

The 4000212-020 is typically used wherever a Triconex Tricon TMR safety PLC is deployed and reliable field wiring is critical:

• Oil & Gas (ESD, HIPPS, BMS, compressor protection)

• Chemicals & Petrochemicals (process shutdown, interlocks)

• Power Generation (boiler/burner management, turbine auxiliaries)

• Pharmaceuticals & Specialty Manufacturing (safety interlocks, utilities)

A maintenance lead at a Gulf Coast refinery told us, “Swapping in the new FTA saved us a full shift during the turnaround—channel mapping lined up exactly with the I/O card, so the loop checks were straightforward.”

• Reliability – Solid terminals and clear routing reduce loose connections and intermittent faults that are painful to chase.

• Compatibility – Designed for Triconex I/O; helps keep your TMR architecture consistent across cabinets.

• Cost Savings – Cleaner wiring typically means faster commissioning and fewer call‑backs during startup.

• Lifecycle Support – Easier field replacement and documentation alignment with existing Triconex drawings.

• Cabinet environment – Mount inside a properly grounded, ventilated enclosure (IP54 or better is common). Maintain 0–60 °C ambient and avoid condensation.

• Mounting – DIN‑rail or panel mount on a metal backplate. Maintain cable bend radius and keep power and signal segregated.

• Wiring practice – Use ferrules; torque terminals to spec; terminate shields at designated points; separate 24 VDC and AC lines from low‑level analog where possible.

• Safety – De‑energize circuits before servicing. Follow site LOTO and ESD handling for connectors and cables.

• Routine checks – Periodically verify terminal tightness, inspect for discoloration or corrosion, clean dust with dry air, and confirm cable headers are fully seated. No firmware updates are required for passive FTAs.

• Typically CE‑marked; UL/cUL usage depends on cabinet/system certification

• RoHS compliant components are commonly used in this product class

• Designed for use within Triconex safety systems that are IEC 61508 SIL3 capable at the system level

• Supplier warranty: 365 days

Note: The 4000212-020 is a termination accessory; channel assignments and exact pin‑outs typically follow the paired Triconex I/O module. If you share your I/O card model and signal mix (e.g., 24 VDC DI, 4–20 mA AI), I can confirm the precise wiring map and recommended system cable.
