The Triconex PI3381 is a high-performance pulse input module designed for triple modular redundancy (TMR) systems. It provides precise signal measurement and reliable connectivity for magnetic, active, and open-collector sensors.
Flexible Sensor Integration
The PI3381 supports six isolated input channels with a commoned ground. Users can connect differential or single-ended signals, adapting the module to various industrial automation sensors.
Advanced Measurement Capabilities
The Triconex PI3381 offers high-resolution 24-bit measurements and a gear multiple tracking algorithm. It maintains ±0.01% accuracy for high-frequency signals and ±0.1% accuracy for lower-frequency inputs.
