ABB GFD233 3BHE022294R0102 Control Processing Input Module

The ABB 3BHE022294R0101 GF D233 or GFD233 3BHE022294R0101 Analog Module,

designed for use with the ABB Megadrive LCI, serves as a critical component for signal conversion in industrial automation. 

This module can perform both analog-to-digital and digital-to-analog conversions,

making it essential for sensor data acquisition, control systems, and monitoring applications.

The key features of the relay are:

1. Self-Powered Three-Phase Non-Directional Overcurrent GFD233 3BHE022294R0102 and Earth-Fault Protection:

• Provides protection against overcurrent and earth faults with both definite minimum time (DMT) and inverse definite minimum time (IDMT) characteristics.

2. Dual Mode of Earth Fault Measurement:

• Offers the option of internal vector summation or external Current Transformer (CBCT) input for earth fault measurement.

3. Integrated IDMT Curves:

• Incorporates IDMT curves (IEC and Special) within a single product to accommodate time coordination requirements for secondary distribution protection.

4. GFD233 3BHE022294R0102 Protection Blocking by Second Harmonic Measurement:

• Ensures stability during magnetizing inrush of transformers by utilizing second harmonic measurement.

5. Capacitor Discharge Impulse Output:

• Provides a low-energy trip coil for efficient operation.

6. Built-in Hand-Reset Electromagnetic Flag:

• Features a hand-reset electromagnetic flag for trip indication.

7. Easy Setting by DIP Switches:

• Settings are easily adjustable via DIP switches, protected by a transparent cover.

8. Compact Design for Secondary Switchgear Applications:

• Designed to be compact and mountable, suitable for Ring Main Unit (RMU) and secondary switchgear applications.

9. Test Facility:

• Offers a test facility for testing the entire protection scheme, including primary CT, relay, and trip coil.

10. Signal Output for Trip Indication:

• Provides a signal output for trip indication to external systems.
