The Triconex 3636R is a 32-point TMR relay output module designed for safety-critical DCS environments. Featuring SPDT contacts and a wide operating temperature range, it provides fault-tolerant switching for high-reliability industrial automation and emergency shutdown systems.
The Triconex 3636R acts as a high-reliability relay output interface within the Tricon Triple Modular Redundancy (TMR) architecture. This module converts internal system logic into physical contact closures to manage external field devices. By employing a TMR design, the module ensures that a single point of failure does not interrupt the process, providing the fault tolerance required for safety-critical applications such as Emergency Shutdown (ESD) and Fire and Gas (F&G) systems.
This module utilizes Single Pole Double Throw (SPDT) relay contacts to facilitate diverse wiring configurations. The 3636R supports high-integrity switching across various load types, ensuring that the controller maintains precise command over industrial machinery. Because the module utilizes mechanical relay components, it provides inherent galvanic isolation between the sensitive control electronics and the potentially volatile electrical transients of the field environment.
Engineered to operate in extreme industrial climates, the 3636R maintains peak performance across a temperature spectrum of -40°C to +85°C. The hardware features a ruggedized construction that supports an extensive mechanical lifecycle, which significantly reduces the total cost of ownership by extending maintenance intervals. Furthermore, the module carries global certifications, including UL and CE, confirming its adherence to stringent international safety and quality protocols.
Prospective users should note that the 3636R module reached its official discontinuation date on December 31, 2018. While the manufacturer has shifted focus to newer safety platforms, this module remains a vital asset for facilities maintaining legacy Tricon v9 or v10 systems. We continue to support these critical operations by providing certified new and refurbished units to ensure process continuity and safety compliance.
