Why Choose the Finder 99.02.0.024.09 RC Suppression Module?
The Finder 99.02.0.024.09 is a compact RC coil suppression module designed to reduce transient voltage and electromagnetic interference generated when a 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 by an inductive relay coil. 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 6–24 V AC/DC, the 99.02.0.024.09 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.

- Supports reliable operation in industrial control panels.
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 99.02.0.024.09 places an RC network across the relay coil to absorb this 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 automation and machinery control panels.
- Building automation and HVAC control systems.
- Process control and manufacturing equipment.
- Relay circuits located near sensitive electronic equipment.
- AC or DC relay coils requiring transient suppression.
