Product Details

Bently 125720-01 specialized terminal block module


Bently 125720-01 is a specialized terminal block module developed by Bently Nevada (now part of GE Vernova), exclusively designed for the 3500 Series Rotating Machinery Monitoring System. It serves as a standardized, safe connection interface between external field devices (such as eddy current sensors, accelerometers, and speed probes) and the 3500 system’s core monitoring modules (e.g., vibration monitoring modules, keyphasor modules). Its primary role is to simplify wiring, enhance signal stability, and protect the system from field-side electrical hazards. Below is its detailed information:

I. Core Technical Parameters

CategorySpecific Specifications
Applicable SystemDedicated to Bently Nevada 3500 Series Monitoring System (compatible with all 3500 frame versions)
Terminal Configuration16-channel terminal design (each channel corresponds to a set of signal input/output pins), supporting both single-ended and differential signal wiring
Signal Compatibility- Analog signals: 4-20mA current signals (from sensors), ±5V voltage signals (from transmitters)- Digital signals: Dry contact signals (equipment status feedback), open-collector signals
Electrical IsolationChannel-to-channel isolation: 500V AC (rms, 1 minute); System-side to field-side isolation: 1kV AC (rms, 1 minute)
Voltage/Currency RatingMaximum working voltage: 300V AC/DC; Maximum continuous current per terminal: 5A (resistive load)
Environmental Adaptability- Operating temperature: -40°C ~ +70°C- Storage temperature: -55°C ~ +85°C- Relative humidity: 5% ~ 95% (non-condensing, no dew formation)- Altitude: Up to 2000m (no derating required)
Mechanical Specifications- Dimensions (W×H×D): Approx. 101.6mm × 152.4mm × 50.8mm (matches 3500 system frame mounting dimensions)- Weight: Approx. 0.3kg- Mounting method: Rail-mounted (compatible with 3500 system’s standard DIN rail)

1. Standardized Wiring Management

The module adopts a 16-channel modular terminal design, with each channel clearly labeled (e.g., "Signal In," "Ground," "Shield") and color-coded terminals (red for power, blue for signals, green for ground). This eliminates chaotic field wiring, reduces wiring errors (e.g., wrong polarity, loose connections), and significantly shortens on-site installation and commissioning time.

2. Multi-Level Electrical Protection

  • Overvoltage/Overcurrent Protection: Each terminal is integrated with a PTC self-recovering fuse (current rating: 5A). When the field-side current exceeds the limit (e.g., short circuit), the fuse automatically disconnects to prevent damage to the 3500 system’s internal modules; it resets automatically after the fault is resolved, avoiding the need for manual replacement.
  • Signal Isolation: The module’s built-in opto-isolation circuit separates the field-side (high-interference environment) and system-side (precision electronics) signals. This suppresses common-mode interference and ground-loop currents, ensuring that weak sensor signals (e.g., microvolt-level vibration signals) are transmitted to the monitoring module without distortion.
  • Shielding Connection: Dedicated shield terminals are provided for each channel to connect the shield layer of field cables. This effectively reduces electromagnetic interference (EMI) from nearby high-voltage cables or motor drives, improving signal-to-noise ratio (SNR) of sensor data.
