Product Description：

The 135473-01 is a Bently Nevada 3500/25 Keyphasor I/O Module. The isolated Keyphasor I/O module is designed for applications where Keyphasor signals are connected in parallel to multiple devices and isolation from other systems, such as control systems, is required. While designed for magnetic pickup applications, this isolated I/O module is also compatible with and provides isolation for Proximitor* applications provided an external power supply is available. The primary purpose of this I/O module is to measure shaft speed, not phase. Phase measurement is possible, but this I/O module introduces a slightly higher phase shift. The Bently Nevada™ 3500/25 Enhanced Keyphasor Module receives input signals from proximity probes or magnetic pickups and converts them into digital keyphasor signals, indicating when the keyphasor mark on the shaft coincides with the keyphasor sensor.
