Pepperl+Fuchs KFD0-RO-Ex2 Isolator | 3-Way, Passive, 4-20mA, Relay, Hazardous Area, DIN Rail

Pepperl+Fuchs KFD0-RO-Ex2 specifications. 3-way signal isolator, passive, 4-20mA, relay output, DIN rail, for hazardous area.

Product Overview

The Pepperl+Fuchs KFD0-RO-Ex2 is a passive, 3-way isolating signal conditioner designed for use in hazardous areas. It provides electrical isolation between the field (Ex i) and control circuits, accepts a 4-20mA input, and provides a relay output. Operating without a separate power supply, it is powered directly from the input signal loop, making it a simple and cost-effective solution for intrinsic safety (IS) barriers, alarm generation, and logic level conversion in process control systems.
