Product Overview

Core Functions

1. 8-Channel Shaft Signal Acquisition: 8 independent inputs compatible with eddy current displacement probes (-24VDC bias), magnetoelectric velocity sensors, LVDT linear displacement sensors, collecting shaft vibration, shaft displacement, keyphasor and servo valve position signals.

2. TMR Redundancy Compatibility: Adapts to Mark VI triple redundant architecture, three-channel synchronous sampling and hardware voting; single-channel failure does not affect system operation, meeting high-reliability protection requirements.

3. High-Precision Signal Processing: 24-bit Σ-Δ ADC, up to 10kHz sampling rate, anti-aliasing low-pass filtering, achieving sub-micron displacement resolution, accurately capturing high-frequency vibration characteristics.

4. Electrical Isolation & Protection: ≥500Vrms electrical isolation between channels and to ground, built-in overvoltage, overcurrent, surge suppression, probe open/short circuit diagnosis, isolating strong electromagnetic interference to protect system and field equipment.

5. Constant Current Bias Output: Provides -24VDC±1%, 4mA constant current bias per channel, directly driving high-impedance eddy current probes without external power modules.

6. Multi-Interface & Terminals: Top vertical connectors, bottom pluggable terminal strips, D-type connectors, adapting to backplane, field sensors, servo loop wiring, supporting quick installation and maintenance.

7. Real-Time Diagnosis & Status Indication: On-board sensor fault, channel status, power indicators, supports system self-diagnosis, quickly locating probe disconnection, short circuit, gap over-limit issues.

8. Industrial-Grade Stable Design: UL94 V‑0 flame-retardant PCB, wide temperature operation, anti-vibration/anti-EMI design, adapting to harsh industrial environments in power plants.
