TRICONEX 3511 Pulse Input Module

TRICONEX 3511 is a TMR (Triple-Modular Redundant) pulse input module designed for critical industrial safety applications.

 It provides 8 independent, non-commoned isolated input channels, supporting high-frequency pulse signal measurement with 1μs resolution and ±0.01% accuracy (1000–20,000 Hz).

Built with triple redundant architecture, it ensures fault tolerance and continuous operation even with single-point failures. 

It features real-time channel diagnostics, hot-swappable design, and strong anti-interference capability, suitable for harsh industrial environments.

Widely used in oil & gas, power generation, petrochemical, and manufacturing industries for turbine/compressor speed monitoring and safety interlocking. 

We supply original new & refurbished modules with full testing, 12-month warranty, and fast global delivery.
