Description

TRICONEX 3636T 32-Channel Relay Output Module Product Introduction

Product Overview

The TRICONEX 3636T is a high-density, industrial-grade 32-Channel Relay Output Module designed for classic Tricon and Trident Triple Modular Redundancy (TMR) Safety Instrumented Systems (SIS). As a dedicated relay-type discrete output unit, it serves as a peripheral interface for non-critical auxiliary control points, converting system logic commands into mechanical relay switch signals for on-site device drive and status indication. Different from TMR-triplicated solid-state output modules, the 3636T adopts a non-triplicated relay output design while retaining triple-channel signal voting from main processors, balancing high system safety integrity and flexible on-site adaptability.

The module features 32 independent relay output channels, contact switch drive capability and comprehensive link diagnosis functions. It receives three-channel synchronous output signals from the Tricon main processor, executes internal majority voting logic, and drives individual relay contacts to ensure consistent and reliable output actions. Certified to comply with industrial safety design specifications, it supports online hot-swap maintenance, G3 harsh environment operation and 24/7 stable auxiliary loop control. Widely applied in petrochemical, natural gas, thermal power and coal chemical industries, it is mainly used for annunciator panel drive, remote status indication, auxiliary interlock trigger and legacy relay loop adaptation, providing high-density and cost-effective output expansion for SIS systems.

Core Technical Specifications & Product Specifications

Core Main Functions

4.1 High-Density 32-Channel Relay Output Drive

The 3636T integrates 32 independent relay output channels in a single module, realizing high-density discrete signal output expansion for SIS systems. It can stably drive on-site auxiliary equipment such as annunciator panels, status indicator lights, local alarm horns and intermediate relay groups, meeting the large-scale auxiliary status display and prompt demands of industrial safety systems. The independent channel design avoids mutual interference between loops and ensures accurate and independent output of each signal.

4.2 Triple-Channel Signal Voting & Stable Output

Although adopting non-triplicated relay output hardware, the 3636T inherits Tricon’s high-safety logic mechanism. It synchronously receives output instructions from three independent main processor channels and executes internal 2oo3 majority voting before driving relay contacts. This mechanism effectively avoids false output actions caused by single-channel processor abnormalities, ensuring the accuracy and consistency of auxiliary loop output and maintaining the overall safety integrity of the SIS system.

4.3 Legacy Equipment & Traditional Loop Adaptation

The module is specially designed for the docking of modern SIS safety systems and traditional industrial auxiliary loops. Its mechanical relay contact output mode is perfectly compatible with old-fashioned intermediate relays, conventional alarm panels and non-intelligent indication equipment that cannot adapt to solid-state signal output. It solves the problem of difficult renovation and poor compatibility of old factory auxiliary control loops, realizing seamless upgrade of old systems without replacing on-site terminal equipment.

4.4 Full-Coverage Channel Fault Self-Diagnosis

The 3636T supports real-time self-diagnosis of all output channels and internal relay status. It can accurately identify common faults such as channel output abnormality, relay switching failure, link disconnection and load anomaly. It automatically generates fault codes and operation logs, uploads alarm information to the upper monitoring platform, helps maintenance personnel quickly locate faulty channels, and reduces hidden dangers of auxiliary loop failure.

4.5 Zero-Downtime Online Maintenance & Stable Operation

Consistent with Tricon series unified industrial design standards, the 3636T supports full online hot-swap function. Module replacement, channel function debugging, output logic modification and fault maintenance can be completed during normal system and production operation. The maintenance process will not affect the normal operation of core safety loops and other auxiliary channels, realizing 24/7 uninterrupted stable output of system auxiliary signals.

Core Product Features

5.1 Ultra-High Channel Density & Space Saving

With 32 output channels integrated in a single module, the 3636T greatly improves the rack space utilization rate compared with traditional low-density output modules. It can complete large-scale auxiliary signal output expansion with fewer slots, effectively reducing cabinet volume, simplifying system wiring layout, and lowering overall project construction and integration costs.

5.2 Safety Voting Logic & Low False Action Rate

Equipped with triple-channel signal voting mechanism, the 3636T eliminates the risk of false output caused by single-point logic errors. Even if individual processor channels are abnormal, the internal majority voting algorithm can filter wrong instructions, ensuring that relay output actions are completely consistent with safety logic settings, and providing reliable guarantee for auxiliary alarm and status indication accuracy.

5.3 Strong Compatibility & Wide Application Adaptability
