Triconex 3636T Non-Triplicated Relay Output Module
Product Overview
The Triconex 3636T is a high-reliability non-triplicated relay output module engineered for non-critical industrial automation applications requiring fail-safe actuation and robust signal conditioning. As part of the Triconex Trident Safety Instrumented System (SIS) ecosystem, this module delivers precise control over discrete loads while maintaining compatibility with Triconex’s Triple Modular Redundancy (TMR) architecture. Designed for annunciator panels, alarm systems, and auxiliary control circuits in oil & gas, power generation, and process industries, the Triconex 3636T ensures seamless integration into safety-critical environments where SIL 3 compliance is mandated for the broader systemse.com.
Featuring 32 isolated relay output channels with normally open (NO) contacts, the Triconex 3636T supports a wide voltage range (125 VAC/VDC) and current rating (2 A per channel), making it suitable for driving solenoid valves, motor starters, and indicator lights. Its advanced loop-back verification circuitry continuously monitors relay operation, detecting open circuits, short circuits, and contact degradation within milliseconds. The module’s hot-swap capability allows online replacement without system interruption, reducing downtime during maintenance. With 2,500 VDC channel-to-bus isolation, it withstands harsh electrical noise and transient voltage spikes common in industrial settings.
The Triconex 3636T leverages Triconex’s Total Fault Management (TFM) technology to provide real-time diagnostic feedback, including LED status indicators and chassis alarm activation for faulted channels. While non-triplicated, it aligns with Triconex’s SIL 3-certified platform, ensuring compliance with IEC 61508:2010 when used in redundant configurations. Its compact form factor and compatibility with Trident chassis simplify integration into existing distributed control systems (DCS), while industry-standard certifications (CE, UL, FM, CSA) ensure global applicability.
