Why Choose the Finder 99.02.0.060.09 RC Suppression Module?
The Finder 99.02.0.060.09 is a compact RC relay coil suppression module designed to reduce transient voltage and electromagnetic interference generated when an inductive relay coil is switched off. As part of the Finder 99 Series indication and EMC suppression module range, it provides a convenient plug-in solution for protecting control equipment and improving switching reliability.
The module incorporates a resistor-capacitor network that absorbs and limits the voltage transient produced during relay coil de-energisation. This helps reduce electrical noise, contact arcing and interference that could otherwise affect PLC outputs, electronic controllers, sensors and nearby control wiring.
Designed for relay coils operating from 28–60 V AC/DC, the 99.02.0.060.09 can be used with either alternating-current or direct-current control circuits. Its plug-in construction allows rapid installation into compatible Finder relay sockets without requiring separate suppression components or additional panel wiring.

- Indication-free design dedicated to transient and EMC suppression.
Reliable Relay Coil and EMC Protection
Relay coils are inductive loads that can produce a high-voltage transient when their supply is interrupted. Without suitable suppression, this transient can cause electrical interference, accelerate contact wear and place additional stress on PLC outputs, transistors and other switching devices.
The Finder 99.02.0.060.09 places an RC network across the relay coil to absorb switching energy and reduce the resulting voltage spike. Unlike a recovery diode, an RC suppressor can operate with both AC and DC coils and generally avoids the same increase in relay release time.
Typical Applications
- PLC-controlled relay output circuits.
- Industrial machinery and automation control panels.
- Building automation and HVAC systems.
- Process control and manufacturing equipment.
- Relay circuits located near sensitive electronic equipment.
- AC or DC relay coils requiring transient suppression.

Frequently Asked Questions
What is the Finder 99.02.0.060.09 used for?
This module suppresses transient voltage and electromagnetic interference generated when an inductive relay coil is switched off.
What voltage range does the module support?
The Finder 99.02.0.060.09 is designed for relay coils operating from 28–60 V AC/DC.
Can this module be used with both AC and DC relay coils?
Yes. Its RC suppression circuit is suitable for both AC and DC relay coils and does not require a specific connection polarity.
How does an RC suppression module protect control equipment?
The resistor-capacitor circuit absorbs the relay coil’s switching transient, reducing voltage spikes and electrical noise that could affect PLC outputs and nearby electronic equipment.
Does the Finder 99.02.0.060.09 include an LED indicator?
No. This model is a dedicated RC suppression module without LED indication; a separate Finder 99 Series LED module should be selected where visual coil-status indication is required.
Trusted for Relay Coil Suppression
Finder 99 Series modules are used by control-panel builders and automation engineers to reduce relay switching transients, improve electromagnetic compatibility and protect sensitive control equipment.
