Why Choose the Finder 99.01.9.060.90 LED and Diode Suppression Module?
The Finder 99.01.9.060.90 is a compact and reliable red LED indication and diode suppression module designed for industrial DC 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 inductive voltage transients generated during relay switching.
This module features an integrated red LED indicator and a flyback diode. The LED illuminates when the relay coil is energised, providing a convenient visual indication of the control circuit status. The diode suppresses the reverse voltage spike generated when the relay coil is switched off, helping protect connected PLC outputs, electronic switching devices and other sensitive automation equipment.
With an operating voltage range of 28–60 V DC and a standard-polarity configuration with positive connected to terminal A1, the Finder 99.01.9.060.90 is suitable for DC relay systems operating within this voltage range, including nominal 48 V DC applications. Its compact plug-in construction allows straightforward installation into compatible Finder 96 Series relay sockets, making it a practical accessory for industrial control panels and machine automation systems.

Reliable DC Relay Coil Indication and Back-EMF Protection
Industrial relay coils are inductive electrical components that store energy in a magnetic field while energised. When the supply voltage is removed, the collapsing magnetic field can generate a high reverse voltage transient capable of damaging sensitive electronic switching components or creating electromagnetic interference. The Finder 99.01.9.060.90 uses an integrated recovery diode to provide a discharge path for the stored coil energy, limiting voltage spikes and helping protect connected control equipment.
The module also incorporates a red LED indicator that provides immediate visual confirmation when voltage is applied to the relay coil. This makes it easier for maintenance engineers and panel builders to identify energised relay circuits and troubleshoot electrical faults. The module uses standard DC polarity with positive connected to terminal A1. Because diode suppression allows coil energy to dissipate more gradually, it can increase relay release time. Applications requiring rapid relay release should consider a suitable alternative suppression method, such as a varistor or RC network.
Typical Applications
- Industrial electrical control panels and switchgear assemblies.
- PLC transistor output protection and relay interface circuits.

- Finder 56 Series industrial power relay installations.
- Manufacturing machinery and automated production equipment.
- Motor control and auxiliary switching circuits.
- Building automation and HVAC control panels.
- Electrical distribution and control cabinets.
- Relay coil status monitoring, maintenance and fault diagnosis.
