Description


ABB Relay RXSF1 RK2711019-AS DC220-250V

ABB Relay RXSF1 RK2711019-AS offers reliable DC220-250V protection for industrial machinery with a compact design and advanced features.

ABB Relay RXSF1 RK2711019-AS is a compact and efficient DC220-250V industrial relay designed for reliable power protection and control in industrial automation and machinery applications. It features a compact design, robust construction, and advanced protection functions.

Engineer's Quick Brief

  • Core Function: Electromechanical target/signal relay designed for clear visual indication and contact multiplication in protective relaying schemes.
  • System Compatibility: Fully integrates with the modular ABB COMBIFLEX plug-in system (occupies 1 seat, typically 2U 6C).
  • Voltage & Reliability: Operates at a high continuous DC voltage of 220-250V DC, ensuring stable performance in critical substation battery environments.

Product Overview

The ABB RXSF1 RK2711019-AS is an industrial-grade electromechanical signal relay belonging to the renowned COMBIFLEX family. Engineered for control and protection panels, this target relay provides distinct visual flag indication upon operation, alerting operators to specific fault conditions. Its high-voltage 220-250V DC coil makes it ideal for direct connection to standard ungrounded station battery systems without the need for voltage dropping resistors.

Application Matrix

  • Substation Protection Panels: Acts as a reliable trip indicator for primary protection relays (distance, differential, overcurrent) running on 220VDC battery banks.
  • Alarm Annunciation: Multiplies contacts to trigger local SCADA alarms, audible sirens, and event loggers simultaneously upon a fault event.
  • Control Sequences: Utilized in interlocking and tripping logics where high immunity to transient voltages is required.

Troubleshooting & FAQ

Q: How do I reset the red target flag on the RXSF1 relay after it has tripped?
A: The RXSF1 features a manual reset mechanism. You can reset the mechanical red target by gently pushing or rotating the reset knob/pin located on the clear plastic front cover of the relay module. Ensure the fault condition is cleared before resetting.
Q: Can I mount the RK2711019-AS directly onto a standard 35mm DIN rail?
A: No. Like all COMBIFLEX relays, the RXSF1 requires a dedicated COMBIFLEX terminal base (such as the RXZ 21 or RXZ 41) and mounting frames (like the RHGX series) for installation. These frames can then be adapted for panel or rack mounting.
Q: What is the typical pick-up voltage for a 220-250VDC coil?
A: According to standard ABB specifications, auxiliary relays typically pick up at approximately 80% of their lower rated voltage (e.g., ~176V DC for a 220V rated coil) to guarantee operation during battery voltage dips.

Cross-Reference Guide

When engineering a new panel or replacing existing units, consider the following COMBIFLEX alternatives based on your functional requirements:

  • Alternative Voltages: Other variants in the RK 271 series exist for 24V, 48V, 110V, and 125V DC. Ensure the coil voltage matches your station battery.
  • General Auxiliary Functions: If no visual target flag is required, consider the ABB RXMA 1 series (e.g., RK 211 variants) for standard contact multiplication.
  • Heavy Duty Tripping: If the relay needs to break heavy inductive DC loads (like breaker trip coils), consider the ABB RXME 1 or RXMH 2 series equipped with heavy-duty contacts and magnetic blowouts.
