Product Introduction
The Triconex 3636A Relay Output Module is a safety-critical component designed for use within the Tricon™ fault-tolerant safety and control system. Developed by Triconex, a trusted brand under Schneider Electric, this module serves as a high-integrity output interface in a wide array of process industries, particularly where reliability, safety compliance, and deterministic response are non-negotiable.
The 3636A is a 32-channel relay output module, capable of switching field devices with electrical isolation and mechanical robustness. It provides normally open (NO) dry contacts and is suitable for controlling actuators, solenoids, alarms, and other final elements in Safety Instrumented Systems (SIS). This module is certified for use in SIL 3 applications according to IEC 61508 and is frequently used in emergency shutdown (ESD), fire and gas (F&G), and turbine protection systems.
Its modular design ensures hot-replaceability, field diagnostics, and seamless integration with Tricon system architecture.
