Description

The Triconex 3636R is a high-density relay output module designed for safety-critical interlocks and emergency shutdown (ESD) applications. As a core component of the Tricon safety system, it provides isolated digital output switching to interface with high-power field actuators, alarm systems, and solenoids. The module is engineered for use in demanding industrial environments such as oil refineries, chemical processing plants, and power generation facilities, ensuring reliable operation through robust galvanic isolation and continuous internal health diagnostics.

Features

• 32 isolated output channels for high-density switching requirements.
• Galvanic isolation between field wiring and the control system logic bus to prevent fault propagation.
• Integrated suppression circuits to mitigate contact arcing during inductive load switching.
• Supports triplicated system voting architecture for high-availability safety loops.
• Hot-swappable design allows for module replacement under power without interrupting adjacent field devices.

Applications

The 3636R is typically deployed in Triconex safety instrumented systems (SIS) for:

• Emergency Shutdown (ESD) systems.
• Fire and Gas (F&G) detection and suppression control.
• Critical process interlocks requiring high-current switching.
• Interface with field solenoids, relays, and alarm annunciators.

Technical Specifications

Installation Guidelines

• Ensure the Tricon chassis is powered down or configured for hot-swapping before installation.
• Use appropriate ESD protection when handling the module to prevent damage to internal logic components.
• Verify that field wiring is properly shielded and routed away from high-EMI sources to maintain signal integrity.
• Ensure all terminal connections are secure and that the module is fully seated in the backplane to ensure proper contact.
• Check that the voltage ratings of the field devices do not exceed the module's 2 A per point capacity.

FAQ

Is the 3636R module hot-swappable?

Yes, the 3636R is designed to be hot-swapped while the chassis is powered, allowing for maintenance without requiring a system-wide shutdown.

What is the primary function of the 3636R?

The 3636R provides 32 channels of isolated relay outputs, primarily used to drive field devices in safety-critical applications where galvanic isolation is required to protect the control system.
