Why Choose the Finder 99.01.0.230.08 LED Indication and Protection Module?
The Finder 99.01.0.230.08 is a plug-in LED indication and EMC suppression module designed for compatible Finder relay sockets. Part of the Finder 99 Series, this accessory combines a red LED indicator with an integrated varistor, providing visual indication of relay coil energisation and suppression of transient overvoltages generated during switching.
Designed for an operating voltage range of 110–240 V AC/DC, the Finder 99.01.0.230.08 provides a convenient way to add indication and coil protection to compatible industrial relay assemblies. The red LED illuminates when the appropriate voltage is applied, helping maintenance personnel identify energised relay circuits during commissioning, inspection and troubleshooting.
The integrated varistor helps limit voltage transients associated with relay coil de-energisation, reducing electrical interference that could otherwise affect nearby control equipment. Its compact plug-in construction allows the module to be fitted to a suitable Finder relay socket without requiring a separate externally wired suppression component.

The Finder 99.01.0.230.08 is an accessory module rather than a relay or relay socket. Relay contact current ratings, socket mounting specifications and load switching capabilities are determined by the associated relay and socket, not by this indication module.
Reliable Relay Indication and EMC Protection for Industrial Automation
Industrial relays are frequently used to switch control signals, auxiliary circuits and electrical loads. When a relay coil is energised or de-energised, operators may need to identify its electrical status and minimise switching-related interference. The Finder 99.01.0.230.08 addresses both requirements by combining a visible red LED with an integrated varistor in a single plug-in accessory.
The LED provides an immediate visual indication when the appropriate coil supply voltage is present, supporting fault-finding and maintenance activities. Meanwhile, the varistor helps limit transient voltage peaks produced by inductive switching, supporting more dependable operation of nearby control equipment.
Because the module is designed to fit compatible Finder relay sockets, it can be incorporated into suitable relay interface assemblies without adding a separately mounted indicator or suppression device. This makes it particularly useful in industrial control cabinets where compact installation, clear indication and maintainable wiring are priorities.
Typical Applications
- Industrial relay coil indication and suppression.
- PLC output relay interface assemblies.
- Machinery control panels and electrical control cabinets.
- Industrial automation and process control systems.
- Motor control auxiliary relay circuits.
- Electrical switching and interlocking systems.
- Industrial signalling and monitoring equipment.
- Building automation and control installations.
- OEM machinery and electrical panel manufacturing.
- Maintenance and troubleshooting of compatible relay circuits.
- Applications requiring combined LED indication and varistor suppression.
