Why Choose the Finder 99.80.0.230.98 LED and Varistor Suppression Module?
The Finder 99.80.0.230.98 is a compact and reliable green LED indication and varistor suppression module designed for industrial relay control circuits. As part of the established Finder 99 Series coil indication and EMC suppression module range, it combines visual relay coil status indication with protection against transient overvoltages generated during relay switching.
This module incorporates a green LED indicator and an integrated voltage-dependent resistor (varistor). The LED illuminates when the associated relay coil is energised, providing immediate visual confirmation of the control circuit status. The varistor helps suppress voltage spikes produced when the relay coil is switched off, reducing electromagnetic interference and electrical stress on connected switching devices.
With an operating voltage range of 110–240 V AC/DC, the Finder 99.80.0.230.98 is suitable for common industrial control supplies, including nominal 230 V AC relay circuits. Its compact plug-in design enables straightforward installation into compatible Finder 95 Series relay sockets, including 95.83.3, 95.85.3 and 95.95.3, making it a practical accessory for industrial automation, machinery control and electrical panel assemblies.

Reliable Relay Coil Indication and EMC Suppression
Industrial relay coils are inductive electrical components that store energy in a magnetic field while energised. When the coil supply is interrupted, the collapsing magnetic field can produce a high-voltage transient that may interfere with nearby electronic equipment or place additional electrical stress on switching devices. The Finder 99.80.0.230.98 uses an integrated varistor to limit these voltage peaks, helping improve electromagnetic compatibility and protect associated control circuitry.
The module also incorporates a green LED indicator that provides immediate visual confirmation when voltage is applied to the associated relay coil. This simplifies commissioning, routine maintenance and troubleshooting. Unlike a conventional flyback diode, the varistor suppresses voltage transients while causing only a slight increase in relay release time. The module supports both AC and DC control supplies, although DC installations require the positive supply to be connected to terminal A1 for correct LED operation.
