Description
The Bently Nevada 3500/40M 125808-01 Proximitor ET Block Euro Style Connectors is a four-channel monitor module from the Bently Nevada 3500 Series machinery condition monitoring system. The 3500/40M 125808-01 accepts input from Bently Nevada proximity transducers, conditions the signal to provide various vibration and position measurements, and compares the conditioned signals with user-programmable alarms.
The 3500/40M 125808-01 provides machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms. It also provides essential machine information for both operations and maintenance personnel. Each channel of the 3500/40M 125808-01 can be programmed with the 3500 Rack Configuration Software to perform any of the following functions: radial vibration, eccentricity, REBAM, thrust position, or differential expansion.
The 3500/40M 125808-01 programs monitor channels in pairs. The monitor channels can perform up to two of these functions at a time. Channels 1 and 2 can perform one function, while channels 3 and 4 perform another (or the same) function. Each channel, depending on configuration, typically conditions its input signal to generate various parameters called static values. You can configure alert setpoints for each active static value and danger setpoints for any two of the active static values on the 3500/40M 125808-01.

Features:
- Four-Channel Monitoring Capability
- Multiple Measurement Functions per Channel Pair
- User-Programmable Alarm Setpoints
- Buffered Transducer Outputs
- External Termination Block with Euro Style Connectors
The 125808-01 is used with the 3500/40M Proximitor I/O Module with External Terminations. In this configuration, the proximity probe and Proximitor sensor wiring can be terminated at the external ET block, while the signal connection to the 3500 rack is made using the 129525 Transducer Signal to External Termination Block Cable. This arrangement is suitable for installations where field termination is located separately from the 3500 rack.
The 125808-01 Bently Nevada Proximitor ET BlockEuro Style Connectors may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 125808-01 uses Euro Style connectors for the external termination interface. Compared with the alternative 128015-01 Proximitor ET Block, which uses terminal strip connectors, the 125808-01 is intended for systems requiring the Euro Style connector configuration. Other related termination products include TMR Proximitor/Seismic ET blocks for systems with redundant or voting architectures.
For a complete external-termination installation, the 3500/40M system requires the appropriate M-version Proximitor Monitor, a compatible external-termination I/O module, the 129525 cable assembly, and the 125808-01 ET Block. Available cable lengths include 1.5 m, 2.1 m, 3.0 m, 7.6 m, 15.2 m, and 30.5 m, depending on the selected cable option.
- Oil & Gas Processing: Applied on drilling rigs, pipelines, and petrochemical facilities
- Power Generation: Deployed in nuclear, hydro, thermal, and wind energy plants
- Heavy Manufacturing: Utilized in pulp/paper, mining, and wastewater infrastructure
- Industrial Turbines: Monitors steam/gas turbines to prevent blade/rotor friction
- Compressors: Tracks high-pressure gas compressors for stable casing/shaft operation
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Sensor to ET Block: Field wires (typically from the proximity probe) land directly on the field-side screw terminals of the 125808-01 block. Ensure shielding is properly terminated to ground to prevent electromagnetic interference.
ET Block to Monitor Module: A pre-engineered system cable connects the terminal block's backplane/system-side connector to the I/O module of the Bently Nevada 3500/40M rack.
Signal Conversion: Once connected, the ET block routes the raw eddy-current transducer signals to the monitor where they are conditioned into usable machine-protection data.
