BENTLY NEVADA 177990-01 Proximitor/Accelerometer/Aeroderivative (PAA) Input Module
Description
The BENTLY NEVADA 177990-01 is a 6-channel plus Keyphasor/speed input module designed to interface with multiple sensor types including –24 V Proximitor sensors, 3-wire accelerometers, charge amplifiers, and differential-output aeroderivative interface modules.
Features
Supports high-temperature charge-coupled accelerometers and dynamic pressure sensors. Provides galvanically isolated magnetic pickup input for speed sensing. Includes buffered transducer outputs via a 15-pin D-sub connector. Enables diagnostics and fault detection via onboard microcontroller outside the protection path.
