Description
RXSF1 is a general purpose contact dc signalling flag relay. The flag is used as an operation indicator following the position of the contacts or mechanically reset, depending on relay version. Flags are available in different colors i.e. yellow and red.
High ac surge immunity allows the relay to be used as intertrip and remote indicating relays. There are versions directly operated from dc current, that may be used e.g. as trip current (target) indicating relays.
A zero voltage indicating type is available which can be used to supervise dc supply voltages.
The standard RXSF1 contains one or two relays with three contacts and red indicating flags.
Applications
Thermal/Nuclear Power Plants: Used for fault logic alarms and status locking of critical auxiliary equipment.
Power Grid Substations/Factory Plants: Serves as an auxiliary unit to the main protection relays, recording the specific circuit where a fault occurred.
Steel Smelting Plants: Provides on-site indication of the tripping status of critical circuit breakers in high-temperature and high-vibration environments.
Petrochemical Plants: Displays logic alarms within explosion-proof control cabinets to ensure the safety of the process chain.
Paper/Precision Machinery Plants: Used for remembering the reasons for emergency shutdowns of production lines.
Main Features
Low power consumption
High resistance to shock and vibration
Twin contacts give high contact reliability even at lower voltages
Dc voltage and dc current operated versions available
Flags that follow armature or mechanically hand reset
FAQ
Q1: What is the difference between RXSF1 and RXME 1?
The core function of RXSF 1 is signal indication (with a mechanical flag), while RXME 1 is mainly used as a re-energizing or auxiliary relay and usually does not have a flag display.
Q2: Why doesn't the flag pop up when the RXSF1 relay trips?
This may be due to insufficient coil energizing time (not reaching the minimum operating pulse width) or internal mechanical components being jammed by dust.
Q3: How do I reset the flag on the RXSF1 after it pops up?
RXSF 1 is designed for "manual reset." The operator must press the reset button below the relay on-site.
Q4: Can the RXSF1 relay be installed in any location?
It is a COMBIFLEX module and must be inserted into a dedicated RX terminal block, typically occupying 2U 6C space.
Q5: Is the RXSF1 product brand new?
Yes, RXSF1 is brand new, original, unused, and factory sealed.
