Product Performance

8937-HN adopts high-precision signal conversion circuits, ensuring analog-to-digital and digital-to-analog conversion error ≤0.1%, meeting industrial-grade measurement accuracy requirements. The single-mode fiber transmission design supports up to 20km transmission without repeaters, with signal transmission delay ≤10ms, ensuring real-time performance of long-distance data transmission.

2.5kV AC electrical isolation between input and output channels effectively blocks electrical connections between hazardous and safe areas, suppresses ground loop interference, with common mode rejection ratio ≥90dB. The wide temperature design ensures stable operation in extreme temperature environments from -40°C to +85°C, with mean time between failures (MTBF) ≥100,000 hours.

The module is compatible with multiple industrial communication protocols, seamlessly interfacing with mainstream control systems, supporting hot-swap maintenance without affecting overall system operation during replacement. The housing uses flame-retardant material certified by UL 94 V-0, enhancing safety in industrial environments.
