Why Choose the Finder 99.01.0.060.09 LED and Diode Module?
The Finder 99.01.0.060.09 is a compact LED indication and diode suppression module designed for compatible Finder industrial relay sockets. As part of the Finder 99 Series coil indication and EMC suppression module range, it provides a convenient solution for visual monitoring of relay coil energisation and suppression of inductive voltage transients in DC control circuits.
The module combines an LED status indicator with an integrated flyback diode. The LED provides visual confirmation when voltage is applied to the relay coil, while the diode provides a discharge path for the energy stored in the coil when its supply is interrupted. This helps protect associated electronic switching devices against potentially damaging voltage spikes.
Designed for DC relay coil applications, the Finder 99.01.0.060.09 is a practical accessory for industrial automation, machine control and electrical panel installations. Its compact plug-in construction allows it to be fitted directly into compatible Finder relay sockets without requiring a separate suppression component or additional panel space.

Reliable Relay Coil Indication and Transient Suppression
Electromechanical relay coils store energy in a magnetic field while energised. When the coil supply is disconnected, the collapsing magnetic field can produce a high-voltage transient that may damage sensitive electronic components or interfere with nearby control equipment. The Finder 99.01.0.060.09 uses diode suppression to provide a controlled path for this stored energy, helping limit the resulting voltage spike.
The integrated LED indicator provides a convenient visual reference for relay coil status, making it easier for engineers to identify active control signals and diagnose electrical faults. Because diode suppression is polarity sensitive, the module must be connected with the correct DC polarity. Flyback diode suppression can also increase relay release time compared with an unsuppressed coil, so the effect on switching behaviour should be considered when designing time-critical control circuits.
Typical Applications
- Industrial electrical control panels and automation cabinets.
- PLC transistor output protection and relay interface circuits.
- DC-operated industrial relay systems.
- Manufacturing machinery and production equipment.
- Motor control and auxiliary switching circuits.
- Building management and automation systems.
- Low-voltage electronic control circuits.
- Relay maintenance, fault diagnosis and status indication.

Frequently Asked Questions
What is the Finder 99.01.0.060.09 used for?
The Finder 99.01.0.060.09 is a relay accessory designed to provide LED status indication and diode suppression of inductive voltage transients in compatible DC relay coil circuits.
How does the diode suppression function work?
The integrated flyback diode provides a path for current from the relay coil when the supply is switched off. This limits the voltage spike generated by the collapsing magnetic field and helps protect connected electronic control devices.
Can the Finder 99.01.0.060.09 be used with AC relay coils?
No. A conventional diode suppression module is intended for DC relay coil circuits. It should not be connected across an AC relay coil because the diode can conduct during part of the AC cycle and cause excessive current.
Does the module require correct polarity?
Yes. The diode suppression circuit is polarity sensitive. Correct DC polarity must be observed during installation to prevent improper operation or damage to the control circuit.
Does diode suppression affect relay switching speed?
Yes. A flyback diode can increase the time required for a relay to release because the stored coil energy dissipates more gradually. This should be considered in applications where fast relay release is important.
