Tricon 3636T Relay Output Module for Non-Critical Points

June 16, 2026 • 3 min read • wayne • Guide

Product Summary

The 3636T Relay Output Module drives non-critical loads like annunciator panels. It receives signals from three processors, votes them, and controls 32 relays. A loopback circuit verifies each switch independently of any load, while continuous diagnostics monitor module health. This design ensures reliable operation for points incompatible with solid-state switches.

Theme: Product Procurement & Buyer Guide for the 3636T Module

Procurement managers need a relay module that provides safe, isolated switching for non-critical points. The 3636T directly addresses this requirement with its non-triplicated architecture. This design makes it an ideal, cost-effective solution for annunciator panels and similar loads. It avoids the expense of high-side solid-state switches where full triple redundancy is unnecessary.

The module handles a maximum voltage range of 155 VAC/VDC. Each of the 32 outputs can switch a resistive load up to 2000 VA or 150 watts. Each output also features a dedicated 2.5A fast-acting fuse for robust overcurrent protection. This per-point fusing prevents a single fault from taking down the entire module.

Point isolation is critical for system integrity. The 3636T provides 1500 VDC isolation between points. This high isolation voltage prevents ground loops and protects downstream equipment. Engineers can confidently interface this module with sensitive external systems without fear of electrical noise.

The module uses normally open (NO) contacts for its output switching. This fail-safe configuration ensures that a power loss de-energizes all relays. The system then defaults to a safe, off state. This is a standard safety requirement for many industrial control applications.

For installation, the 3636T requires a separate External Termination Panel (ETP). This panel connects to the Tricon backplane via a dedicated cable interface. This separation simplifies wiring and maintenance. You can replace the module without disturbing field wiring, reducing downtime during service.

The module also supports hot-spare functionality. You can insert a spare 3636T into the chassis while the system operates. The spare activates automatically upon a primary module failure. This capability maximizes system availability for critical processes that cannot tolerate extended downtime.

Diagnostic indicators provide immediate visual feedback. Each of the 32 points has its own output status light. The module also features PASS, FAULT, and ACTIVE indicators. A fault triggers the chassis alarm, alerting operators to a problem instantly. This speeds up troubleshooting and reduces mean time to repair.
