Structure & Composition

This module integrates multiple functional elements within its compact enclosure:

• Signal acquisition and conditioning circuits for processing inputs from various sensors
• Local processing board that filters, scales, and converts vibration signals
• Communication interfaces including Ethernet and status LEDs for diagnostics
• DC‑37 pin connector for interfacing with terminal boards such as the TVBA vibration interface board
• LED indicators (e.g., Attn, Pwr, Link, TxRx) for module status monitoring

The modular design allows easy integration into existing Mark VIe system racks and terminal boards, supporting both simple and redundant configurations.

Key Capabilities

• Multiplexed Vibration Input: Supports 13 channels capable of receiving signals from a range of sensors including proximity probes, velocity sensors, accelerometers, and seismic transducers.
• Multi‑Protocol Communication: Interfaces via Ethernet, commonly to SCADA systems or GE control networks for real‑time data exchange.
• Wide Environmental Range: Built to operate reliably in harsh industrial conditions with a typical ambient temperature range from about –30 °C to +65 °C.
• Frame Rate Flexibility: Sampling frame rates configurable from 3.125 Hz up to 100 Hz, allowing adaptation to different monitoring requirements.
• Probe Power Support: Delivers bias power (commonly –24 VDC) to transducers with typical current capacity (~12 mA per sensor), making it suitable for proximity and vibration sensors.
