BENTLY NEVADA 125800-01 Keyphasor I/O Module
1. Product Description
The BENTLY NEVADA 125800-01 Keyphasor I/O Module is a compact, high-performance solution designed for the BENTLY Nevada 3500/25 Enhanced Keyphasor system. This two-channel module interfaces with proximity probes or magnetic pickups to detect shaft keyphasor marks, converting analog signals into digital triggers for precise rotational synchronization. It plays a critical role in machinery protection systems by enabling accurate vibration analysis, phase-locked monitoring, and overspeed detection. With internal terminations and a half-height form factor, the module ensures seamless integration into existing 3500 series racks, supporting applications such as turbine control, compressor health monitoring, and rotating equipment diagnostics.
