This module is engineered to provide electrical isolation for Keyphasor signals, allowing them to be distributed across multiple devices or systems, such as external control networks or data acquisition systems, without introducing ground loops or electrical interference. It is primarily utilized for processing signals from magnetic pickups or proximity probes to generate precise digital Keyphasor pulses, which serve as the phase reference for vibration analysis and shaft speed monitoring in rotating machinery.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Isolation:\u003c\/strong\u003e Ensures signal integrity by isolating Keyphasor inputs from downstream monitoring or control equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Input Channels:\u003c\/strong\u003e Supports up to two independent inputs from proximity probes or magnetic pickups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Conversion:\u003c\/strong\u003e Converts raw analog probe\/pickup signals into reliable digital pulses for the 3500 rack system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Compatibility:\u003c\/strong\u003e Fully integrated with the 3500 Series rack architecture, supporting redundant configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Sensing:\u003c\/strong\u003e Designed for magnetic pickup applications and compatible with Proximitor sensor inputs when external power is applied.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is essential for critical rotating equipment, including steam and gas turbines, compressors, and large pumps.
