Finder 99.02.9.220.99 EMC LED Module with Diode, Green, 110-220V DC, A1+ Polarity

The Finder 99.02.9.220.99 is a specialized EMC LED suppression module designed to enhance the functionality of industrial relay systems. It integrates a green LED indicator for clear visual status monitoring and a protection diode to suppress voltage spikes generated by relay coils. Engineered for 110-220V DC operation with A1+ polarity, this module ensures stable performance and protects sensitive control electronics from transient surges.

Advantages

This module provides a dual-function solution by combining coil suppression with status indication in a compact form factor. The integrated protection diode effectively mitigates back-EMF, which helps extend the operational lifespan of both the relay and the connected control equipment. The bright green LED provides immediate visual feedback, allowing maintenance personnel to quickly identify the status of the relay circuit, thereby reducing downtime during troubleshooting and routine inspections.

Suitable for

• Industrial automation control panels
• Relay-based switching systems
• Diagnostic monitoring in electrical cabinets
• Protection of PLC outputs and control circuits

This module is not suitable for AC voltage applications, as it is specifically designed for 110-220V DC circuits. It should not be used in environments where the polarity requirements do not match the A1+ configuration, as incorrect installation will prevent the LED from functioning and may compromise the protection circuit.

Key specifications

• Operating voltage: 110-220V DC
• Indicator color: Green
• Polarity: A1+
• Function: LED status indication and coil suppression
• Compatibility: Designed for specific Finder relay sockets

To install the module, simply insert it into the designated slot on the compatible relay socket. Ensure that the polarity of the power supply matches the A1+ requirement of the module. Once seated, the module will automatically engage with the relay coil circuit, providing immediate protection and visual indication upon power-up.

What to consider before purchase

• Verify that your relay socket is compatible with the 99.02 series modules
• Confirm that your control system operates on DC voltage within the specified range
• Ensure the A1+ polarity matches your wiring configuration

For optimal performance and safety, always ensure the module is fully seated in the socket before applying power. Regularly inspect the LED indicator to confirm the status of the relay and replace the module if the indicator fails to illuminate during normal operation.
