Product Overview
The TRICONEX 3636R is a 32-channel non-triplicated relay output module for Tricon safety systems, driving non-critical loads like annunciators, lamps, and auxiliary relays with normally-open contacts rated for 125 VAC/VDC at 2 A maximum. Unlike TMR digital outputs, the 3636R serves utility functions in ESD, Fire & Gas, and burner management systems where SIL 2 integrity suffices and high-side switching compatibility is needed. Control room operators and maintenance teams benefit from its point isolation (1,500 VDC), individual output status LEDs, and module health indicators (PASS/FAULT/ACTIVE). Each relay features 2.5 A fast-acting fuses, supporting 2,000 VA resistive switching while preventing fault propagation. DIN-rail or rack-mounted with external terminal panels, the module handles diverse loads from pilot lights to horn drivers in control consoles, providing visual and audible confirmation of safety states without compromising main TMR logic paths.

Key Functions
High-Voltage Relay Switching
32 independent normally-open relays handle 125 VAC/VDC loads up to 2 A continuous, ideal for annunciator panels and auxiliary interlocking. Non-commoned design prevents cross-channel shorts.
Comprehensive Status Indication
Per-point output status LEDs plus module PASS/FAULT/ACTIVE indicators provide immediate visual diagnostics. Simplifies troubleshooting during panel walkthroughs.
Fault Protection
1,500 VDC isolation and 2.5 A fast-acting fuses per output contain arc faults and overloads. Module continues operating healthy channels during single-point failures.
Versatile Load Compatibility
Supports resistive, inductive, and lamp loads up to 2,000 VA peak; minimum 10 mA/5 VDC ensures reliable switching across instrument panels.
Application Scenarios
Control Room Annunciators
Refineries drive window-type annunciators showing ESD, high-high pressure, and pump faults; 32 channels cover entire DCS mimic panels with fused protection.
Fire & Gas Horns and Beacons
Offshore platforms power fire horns, rotating beacons, and status lamps; high-voltage relay capability interfaces directly with 120 VAC building power.
Auxiliary Relay Drivers
Power plants control lockout relay coils and breaker trip indications; isolation prevents ground loops between safety logic and medium-voltage switchgear.
