TRICONEX 8310 Power Module – Reliable backplane power for Tricon TMR safety systems

The TRICONEX 8310 is commonly used as the power module assembly within Tricon TMR safety PLC systems, supplying conditioned, redundant backplane power to the main or expansion chassis. From my experience, it’s a straightforward way to stabilize the system power architecture, especially when you need high availability in ESD, F&G, or turbine protection applications. You might notice that in many cases it’s deployed alongside complementary AC or DC variants in the same family to build a fully redundant power set.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; not more than one month at the latest
• Payment terms: 50% advance payment, full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Redundant power architecture: Typically supports multi-module redundancy to keep the Tricon chassis powered during single-module faults.
• Backplane power stabilization: Conditions and distributes power to system processors and I/O without field signal terminations—clean separation from process wiring.
• Hot-replacement in redundant setups: In most cases, you can replace a failed power module online if the redundant pair is healthy, minimizing downtime.
• Chassis compatibility: Designed for TRICONEX main/expansion chassis; installation is slot-based with front access.
• SIS-ready environment: Built for continuous operation in safety instrumented systems where power integrity is critical.

Technical Specifications

Application Fields

Plants running safety instrumented systems typically use the TRICONEX 8310 in power bays where uninterrupted chassis power is mandatory. I see it most in:

• Emergency Shutdown (ESD) and High Integrity Pressure Protection (HIPPS)
• Fire & Gas (F&G) detection and suppression systems
• Boiler/Burner Management Systems (BMS)
• Turbomachinery control and protection
• Refining, petrochemical, upstream oil & gas, power generation, and pharmaceuticals

Advantages & Value

• High availability: Redundant design seems to maintain backplane power during single failures, reducing spurious trips.
• System compatibility: Built for the Tricon safety system—no guesswork on fit or backplane alignment.
• Lifecycle savings: Drop-in replacement keeps your wiring and cabinet layout unchanged; maintenance teams don’t need new procedures.
• Serviceability: Front-access replacement and status indication (where applicable) help technicians work faster during turnarounds.

A maintenance supervisor I worked with summed it up well: “We swapped an 8310 module during a scheduled window; the redundant set kept the chassis alive, and we were back in sequence in minutes.” That’s typically the kind of low-drama result you want in a SIL environment.

Installation & Maintenance

• Cabinet & environment: Install in a clean, dry control cabinet with adequate ventilation; maintain ambient 0–60 °C and avoid corrosive atmospheres.
• Chassis placement: Mount only in designated power slots of the TRICONEX main or expansion chassis; verify locking levers and connectors are fully seated.
• Grounding & wiring: Use proper earth bonding to the cabinet; route AC/DC feeds separately from low-level signals to reduce noise coupling.
• Redundancy & hot-replacement: If two or more power modules are fitted, you can typically replace a failed unit online. Confirm system status and follow site MOC/Loto procedures.
• Routine checks: Quarterly visual inspection for connector seating, dust buildup, and any thermal discoloration; clean with dry air and re-torque terminal screws as per the manual.
• Firmware: Power modules generally don’t carry user firmware, but it’s good practice to keep controller and diagnostics tools at approved revisions.

Quality & Certifications

• Typically compliant with CE and UL/CSA electrical safety requirements for industrial control equipment
• Designed for use within TRICONEX systems assessed to IEC 61508 SIL3 when properly engineered
• RoHS conformity may vary by production year; documentation available on request
• Warranty provided by us: 365 days

If you’re refreshing spares or closing out a safety system upgrade, the TRICONEX 8310 is a safe choice to keep the TMR chassis powered and stable. I’m happy to help verify slot compatibility against your current main/expansion chassis and redundancy design before you place the order.
