Product Description
The 3481S2 is a high-precision Analog Output Module designed for the Triconex Triple Modular Redundant (TMR) safety platform. It delivers reliable, continuous 4–20 mA control signals for final elements such as control valves, actuators, and analog indicators, ensuring safety-critical processes are managed with extreme accuracy and minimal latency.
Engineered for Safety Instrumented Systems (SIS), the 3481S2 features Forced-Switch Diagnostics (FSD), allowing the module to self-test output circuitry without interrupting operations. In the event of a channel failure, the module achieves a typical 1 ms switch time, maintaining output stability and protecting high-hazard industrial processes.
