Product Description
The Triconex SDO204 is a safety digital output module designed for the Tricon Triple Modular Redundant (TMR) control system. Engineered to drive critical field devices, such as solenoid-operated valves (SOVs), motor starters, and emergency signaling equipment, the SDO204 delivers fault-tolerant, SIL 3-compliant outputs for mission-critical Safety Instrumented Systems (SIS).
Its robust architecture ensures that safety-critical actions are executed reliably, even in harsh industrial environments, while providing seamless integration with the Tricon modular chassis.
