125800-01 | Bently Nevada Keyphasor I/O Module

Introduction

The 125800-01 Isolated Keyphasor I/O Module is a versatile and reliable device designed to handle Keyphasor signals in a wide range of industrial applications. This module is particularly valuable in environments where signal isolation is critical, such as when multiple devices are connected in parallel or when integration with control systems is required.

Key Features and Capabilities

Signal Compatibility: Primarily designed for Magnetic Pickup applications, the module also supports Proximitor applications with an external power supply.
Enhanced Performance: Key features include once-per-turn event signal generation, field-upgradeable firmware, and asset management data reporting for improved system monitoring.
Precise Measurements: Although designed for speed measurement, the module also provides phase measurements. However, it experiences a slightly higher phase shift compared to non-isolated I/O modules.
