125800-01 key phasor I/O module primarily

The Bently 125800-01 is a key phasor I/O module primarily used in the Bently Nevada 3500 system. It receives signal input from close to the pickup and converts it into a digital key phasor signal. The module also has TCP/IP and serial (RS232/RS422/RS485) communication capabilities for a variety of applications such as bearing speed monitoring, terrain change detection, machine fault identification and rotating machinery protection.

Product parameters are as follows:

Model: 125800-01
Power supply: 24VDC
Input: 1 keyed input
Resolution: 0.1 degrees
Accuracy: ±0.25%FS
Operating temperature: -40°C to +70°C

The Bently Nevada 125800-01 Key Phase I/O module is an essential part of the mechanical protection system, providing accurate shaft speed measurements that maintain high accuracy even at low speeds and noisy environments. In addition, the module is capable of measuring and monitoring phase information between multiple reference points to detect potential misalignment, rotor eccentricity, and other mechanical issues. It also provides non-isolated and isolated analog outputs, ensuring compatibility with various control and monitoring systems. The modules feature a robust IP65-rated housing that can withstand harsh industrial environments and vibrations.

In addition, the 125800-01 is part of the Bently Nevada 3500/25 series of Keyphasor I/O modules for converting speed and displacement sensor signals into digital signals for transmission to the Bently Nevada monitoring system.
