Description

The FPS Feeder Protection System monitors voltage and current to provide a comprehensive package of 17 protective functions. The FPS is a modular system with integrated protection, breaker control, metering, and data-logging functions. Operator Interface (FPS-OPI) g Large, bright, 4 x 20 vacuum-fluorescent display g Display metered values g Access set points g Powered by Control Unit g Panel mount or attach directly to Control Unit g Remote mounting (1 .2 km or 4000 ft maximum loop length) g 1/2 DIN size g Hazardous-location certified Control Unit (FPS-CTU) g Current inputs—5-A or 1-A secondary phase current transformers g Voltage inputs—up to 600 V without PTs g Earth-leakage input—5-A or 1-A secondary or sensitive transformer g 8 digital inputs, 5 relay outputs, 1 analog input and output g 24-Vdc supply for OPI and RTD modules, and for digital inputs g IRIG-B time-code input g 1/2 DIN size, surface mount g RS-485 network communications (Standard) g DeviceNet™, Profibus®, or Ethernet communications available Phase Current T ransformers Phase CTs are required to detect phase currents. Ground-Fault Current T ransformer Zero-sequence current transformer detects ground-fault current. Available with 5-A and 30-A primary ratings for low-level pickup. MPS-RTD T emperature Input Module Optional module provides 8 inputs to connect Pt100, Ni100, Ni120, and Cu10 RTDs. SE-IP65CVR-M Cover Optional gasketed, transparent cover for limited access and IP65 protection for an Operator Interface Module.
