Product Description
PEPPERL+FUCHS Safety Barrier Current Driver Repeater KFD0-CS-Ex2.51P
Product Overview
2-channel isolated barrier designed for intrinsic safety applications with 24 V DC loop-powered operation and 0-40 mA current input/output capability.
Key Specifications
- 2-channel isolated barrier design
- 24 V DC loop-powered supply
- Current input/output range: 0 mA to 40 mA
- I/P or transmitter power supply capability
- High accuracy: 1%
- Built-in reverse polarity protection
- Safety certification: Up to SIL 2 (SC 3) according to IEC/EN 61508
Functional Operation
This isolated barrier is engineered for intrinsic safety applications, transferring DC signals from fire alarms and smoke alarms from hazardous areas to non-hazardous areas. The device also supports control of I/P converters, valves, indicators, and audible alarms.
Reverse polarity protection safeguards against damage from wiring errors, while the loop-powered design eliminates the need for additional power supply connections on the control side.
Application Scenarios
Circuit Isolation: Used for isolating circuits to control positioners, I/P converters, and similar equipment. A current source is connected to terminals in the non-explosion-hazardous area.
Current Signal Isolation: Provides isolation for current signals from fire detectors and similar sensors. A voltage source connects to terminals in the non-explosion-hazardous area, with specific measurement current across passive sensors measured using a series resistor (minimum 50 Ω).
