Versatile Input Support for Multiple Sensor Types
The Bently Nevada 125740-01 supports accelerometers, proximity probes, and velocity transducers. This module also accepts temperature, pressure, and 4-20mA signals for comprehensive monitoring. Users can configure each input for specific sensor types and ranges. The versatility reduces the need for multiple specialized modules.
Four Galvanically Isolated Channels
Four independent input channels provide 500V DC isolation for reliable signal acquisition. This isolation prevents ground loops and protects against electrical transients. Each channel includes independent signal conditioning and filtering. Users can connect different sensor types on each channel without interference.
Programmable Signal Conditioning for Each Channel
Users can configure low-pass and high-pass filters per channel for noise rejection. The module provides amplification, linearization, and scaling for various sensors. Each channel includes programmable gain settings for optimal signal levels. This flexibility accommodates different sensor sensitivities and installation conditions.
High-Resolution A/D Conversion
16-bit analog-to-digital conversion provides precise measurement data for each channel. The sampling rate reaches 1 kHz per channel for dynamic signal capture. This resolution ensures accurate vibration and process value measurements. Users can detect small signal changes for early fault detection.
Compact Half-Height Rack Design
The module measures 241 x 152 x 25 mm and weighs 0.75 kg for efficient rack installation. This half-height form factor fits standard 3500 rack configurations. A 25-pin D-sub connector provides field wiring for all sensor connections. Users can replace modules without disturbing field wiring.
Low Power Consumption for Dense Racks
The Bently Nevada 125740-01 draws only 4.5W for minimal heat generation. This low power consumption allows dense rack configurations without thermal issues. The unit operates reliably from -20°C to +65°C ambient temperatures. Users can deploy the module in various industrial environments without concerns.
