Product Description
The Triconex 3704E is a high-density analog input module designed for the Tricon Triple Modular Redundancy (TMR) safety platform. Featuring 64 commoned input points, this module is ideal for large-scale signal acquisition where space efficiency and fault-tolerant reliability are critical. Signals are processed through three independent, isolated paths, ensuring continuous mission-critical logic execution even if a single hardware failure occurs.
Designed for SIL 3 safety systems, the 3704E combines high channel density with the robust fault-tolerant architecture of Tricon TMR controllers.
