EM2291 Safety I/O Module | Triconex SIL3 Certified Device

Triconex EM2291 I/O Module – High-Reliability Safety Instrumented Module

Product Description / Overview

The Triconex EM2291 is an I/O module designed for integration into Triconex Safety Instrumented System (SIS) controllers. It connects field devices such as sensors and actuators to the SIS architecture. Moreover, it supports pulse input signals and general I/O, making it versatile for diverse industrial applications. In addition, its triple modular redundancy (TMR) ensures fault tolerance and continuous operation. Therefore, the EM2291 is ideal for high-availability, safety-critical systems requiring SIL3 compliance.
