TRICONEX 3807 Power Module – 220 VAC Supply for Tricon Safety Systems

Plants using Tricon SIS typically standardize on a mix of power modules to match site utilities. The 3807 is a good fit where 220 VAC feeds are stable and monitored. You might notice that refineries, petrochemical units, LNG trains, offshore platforms, and power generation facilities prefer the 3807 for main and expansion racks, especially when they want consistent spares across multiple cabinets.

• - Emergency Shutdown (ESD) systems and high?integrity pressure protection (HIPPS)




•    - Burner Management Systems (BMS) and boiler/turbine safety controls




•    - Compressor and pipeline protection with TMR logic




•    - Safety interlocks in chemical processing and tank farms

• - Reduced downtime: Hot?swap means maintenance can be planned without shutting down the controller.




•    - Lifecycle confidence: TRICONEX modules tend to have long service lives and stable firmware/hardware baselines.




•    - Interchangeable spares strategy: Many sites pair 3807 (AC) with 3805E/3806E fleets depending on cabinet locations, simplifying inventory across units.




•    - Proven compatibility: Seamless fit with Tricon main/expansion chassis; no adapters or re?wiring in most cases.




•    - Diagnostic clarity: Clear status LEDs help technicians identify issues fast—handy during shift work or audits.

• - Cabinet and power: Mount in the specified Tricon chassis with adequate ventilation; feed from a clean, protected 220–240 VAC source with proper earthing.




•    - Redundancy: Use dual power modules for N+1. Replace a suspect unit while the healthy unit carries the load (observe site MOC and LOTO procedures).




•    - Wiring and protection: Route AC feeds separately from low?level signals; include upstream breakers/fuses as per electrical design standards.




•    - Environmental care: Keep the enclosure free of dust and corrosive vapors; check that inlet temperature stays within the typical 0–60 °C band.




•    - Routine checks: Visually verify LED status, inspect connectors for oxidation, and exercise the redundant swap during scheduled turnarounds.




•    - Spares and revisions: Keep at least one tested spare 3807 on hand; align hardware revisions with the rest of the rack where possible.

The TRICONEX platform is well known for SIL3 applications when used as part of a certified system. The 3807 power module is typically supplied with CE and UL/CSA approvals, and the manufacturing process aligns with ISO 9001 quality practices. RoHS compliance may vary by hardware revision, so it’s worth confirming the exact part/revision before shipment. Standard warranty terms are commonly 12 months from delivery, and extended coverage can be arranged on request.

If you’re standardizing a cabinet build, you may also consider: TRICONEX 3805E (24 VDC power module), TRICONEX 3806E (120 VAC power module), Tricon main/expansion chassis (e.g., 8110/8120/8130), TRICONEX 3008 main processors, and the TRICONEX 4351 communication modules. Selection typically depends on site utilities and the desired redundancy model.
