Product Description
The TRICONEX DI3301 is a 32-channel digital input module, engineered for Schneider Electric’s Triconex safety instrumented systems (SIS). Designed for high-integrity applications, it ensures reliable signal acquisition from critical field devices such as pushbuttons, limit switches, flame detectors, and interlocks. Moreover, its TÜV-certified SIL 3 compliance guarantees the highest safety standards for emergency shutdown (ESD), fire & gas, and turbine or compressor control.
Employing Triple Modular Redundancy (TMR), the DI3301 continuously validates input signals across three independent channels, eliminating single points of failure. Furthermore, the module integrates seamlessly with Triconex controllers and TriStation engineering tools, ensuring fault-tolerant operation across industrial automation systems.
