Why Choose the Finder 99.01.0.024.98 LED and Varistor Module?
The Finder 99.01.0.024.98 is a compact and reliable LED indication and varistor suppression module designed to provide visual relay coil status indication and protection against transient overvoltages in industrial control circuits. As part of the established Finder 99 Series coil indication and EMC suppression module range, it is specifically developed for use with compatible Finder relay sockets in electrical control panels, automation equipment and industrial machinery.
This module combines a green LED indicator with an integrated voltage-dependent resistor (varistor). The LED provides a clear visual indication when the relay coil is energised, while the varistor helps suppress voltage transients generated when the relay coil is de-energised. This combination supports reliable relay operation, simplifies fault identification and helps reduce electrical interference within control systems.
With an operating voltage range of 6–24 V AC/DC, the Finder 99.01.0.024.98 is suitable for low-voltage relay control circuits using either alternating or direct current. Its compact plug-in design allows straightforward installation into compatible Finder 96.72 and 96.74 relay sockets, making it a practical accessory for Finder 56 Series industrial power relay installations.

Reliable Relay Coil Indication and EMC Suppression
Relay coils are inductive components that can generate transient voltage spikes when their supply is interrupted. These voltage transients can contribute to electromagnetic interference and place additional electrical stress on connected switching devices. The Finder 99.01.0.024.98 addresses this issue through an integrated varistor, which limits the voltage peaks generated during relay coil de-energisation and helps improve the electrical compatibility of industrial control circuits.
The module also incorporates a green LED indicator that illuminates when voltage is applied to the relay coil circuit. This provides maintenance engineers and panel builders with a convenient method of identifying energised relay coils without requiring additional indication components. Designed for compatible Finder 96 Series sockets, the module provides a practical combination of visual indication and electrical suppression in a compact plug-in accessory. When used with DC relay coils, the positive supply must be connected to terminal A1 as specified for the module.
