Product Description
The TRICONEX DI3301 S2 is a high-reliability digital input module from Schneider Electric’s Triconex safety instrumented system (SIS) portfolio. Specifically designed for safety-critical industrial applications, it provides fault-tolerant digital signal acquisition in Triple Modular Redundant (TMR) architectures. Moreover, its compact design and robust construction allow seamless integration in tight spaces while resisting harsh environmental conditions such as vibration, temperature extremes, and humidity.
The S2 variant is a special configuration version of the standard DI3301, optimized for flexible installation, connector types, wiring arrangements, and enhanced diagnostics. This module ensures continuous operation even during single module failures, making it ideal for emergency shutdown (ESD), fire & gas systems, turbine and compressor protection, and other high-integrity automation tasks.
