Description

Detailed Specifications for KFD2-CRG2-1.D:

1. Model: KFD2-CRG2-1D

   • Manufacturer: Pepperl+Fuchs
   • Type: Intrinsic Safety Barrier (Signal Isolator)

2. Input Type:

   • Input signal type: Analog current (4-20 mA).
   • Input range: 4-20 mA (standard for many industrial process applications).
   • Maximum Input Current: 20 mA.

3. Output Type:

   • Output signal: Typically, a 0-20 mA or 4-20 mA signal is passed to the next system or control unit.
   • Output range: The signal is passed with galvanic isolation and protection, maintaining integrity without cross-contamination from hazardous zones.

4. Voltage and Power Supply:

   • Supply voltage: 24V DC ± 20% (Common for industrial applications).
   • Power Consumption: Approx. 20 mA at 24V DC.
   • Output current capacity: 20 mA max per channel.

5. Isolation:

   • Galvanic Isolation between the field circuit (potentially hazardous area) and the control circuit (safe area).
   • Isolation voltage: Typically, 250 V (for isolation between input and output).

6. Intrinsic Safety:

   • Safety Approvals:
     • ATEX: Complies with ATEX Zone 0, Zone 1, Zone 2 for explosive atmospheres (potentially hazardous areas).
     • UL: Recognized for use in the United States.
   • Certification: Type approval for hazardous areas (Zone 0 and Zone 1).

7. Response Time:

   • Response time: Typically, in the order of milliseconds (e.g., 2-3 ms depending on the signal type).

8. Temperature Range:

   • Operating Temperature: -20°C to +60°C.

9. Housing:

   • Mounting: Rail-mounted (DIN rail mount).
   • Enclosure: Polycarbonate or similar durable material suitable for industrial environments.
   • Dimensions: 22.5 mm (W) x 99 mm (H) x 114 mm (D).

    • IP rating: Typically IP20 (protection against dust, not waterproof).

11. Weight:

    • Approximately 100 grams.

Applications:

• Intrinsically Safe Control Systems: This module is often used in explosive atmospheres to safely isolate signals coming from hazardous areas to control systems in safe areas.
• Signal Conversion: It can convert an analog current signal (e.g., 4-20 mA) from hazardous areas into a safe, isolated signal for use in a control room or PLC system.
