3636T Triconex Schneider Electric Relay Output Card SIL 3

Product Overview

The TRICONEX 3636T serves as a high-density, safety-critical digital relay output module for the Triconex Safety Instrumented System (SIS). It provides 32 independent channels of "dry contact" relay outputs to drive field devices such as solenoids, motor starters, alarms, and interlock circuits. Built for the most demanding environments, the 3636T utilizes a 6U VME form factor and delivers high-capacity switching while maintaining the rigorous safety standards required for SIL 3 loops. We supply this module as 100% Brand New and Original, ensuring your safety system operates with uncompromised hardware integrity.

Technical Specifications

The 3636T facilitates high-voltage switching and robust isolation between the control logic and field-side equipment.

Engineering Advantages

• Superior High-Voltage Isolation: The 3636T features 1900 VDC isolation between individual channels and between channels and ground. This robust barrier protects the sensitive Tricon backplane from field-side surges, electrical noise, and grounding faults.

• Versatile Signal Compatibility: Unlike standard transistor outputs, the dry contact relays in the 3636T manage both AC and DC loads. It handles up to 2 A at either 24 VDC or 125 VAC/VDC, allowing direct control of heavy-duty actuators without interposing relays in many applications.

• Rapid Fault Mitigation: With a response time of ≤10 ms, the module executes trip commands and safety shutdowns nearly instantaneously. This speed is critical for preventing equipment damage and ensuring personnel safety during process excursions.

• Zero-Downtime Maintenance: The hot-swappable 6U VME design enables technicians to replace the 3636T module while the Tricon system remains fully operational. This eliminates the need for plant shutdowns during hardware maintenance or upgrades.

• Tough Environment Resilience: Engineered for unconditioned industrial spaces, the module operates reliably across a wide temperature range from –40°C to +70°C. The industrial-grade components and protective design withstand the vibration and atmospheric stressors found in oil refineries and offshore platforms.

• High-Density Output: Packing 32 channels into a single VME slot reduces the total cabinet footprint. This allows engineers to manage more interlocks and alarms using fewer racks, lowering overall system costs.

FAQs

1. What is the benefit of using the "T" version (3636T) over standard relay modules?

The "T" designation typically indicates enhanced testing or specific termination compatibility within the Tricon platform. The 3636T provides the high-density 32-channel count required for modern, complex safety logic while offering 1900 VDC isolation that exceeds standard industrial requirements.

2. Can the 3636T control 120VAC solenoid valves directly?

Yes. Each relay contact is rated for 125 VAC at 2 A. This allows the 3636T to drive most standard industrial solenoids and beacons directly, simplifying your wiring and reducing the need for external interposing relays.

3. Is this module compatible with all Tricon versions?

The 3636T is a standard 6U VME module compatible with Tricon v9, v10, and v11 systems. Always verify your specific system's TriStation 1131 software version to ensure the module library supports the hardware revision.

4. How does the module handle inductive loads?

While the relays are robust, we recommend using external suppression (such as diodes for DC or MOVs for AC) across inductive field loads (like large solenoid coils) to extend the contact life and prevent EMI during switching events.
