Why Choose the Finder 99.80.0.230.09 RC Suppression Module?
The Finder 99.80.0.230.09 is a compact RC (resistor-capacitor) suppression module designed for compatible Finder relay sockets and industrial switching relay assemblies. Part of the Finder 99 Series, this plug-in accessory helps manage electrical transients generated when relay coils are switched off, supporting reliable operation in industrial automation and electrical control systems.
Designed for an operating voltage range of 110–240 V AC/DC, the Finder 99.80.0.230.09 provides a convenient suppression solution for suitable AC and DC relay coil circuits. Its integrated resistor-capacitor network helps limit switching-related voltage transients, reducing electrical disturbances that could otherwise affect nearby control and electronic equipment.
Unlike LED indication modules, the Finder 99.80.0.230.09 is specifically an RC suppression accessory. It does not provide an LED status indicator. Its primary purpose is to help control coil switching transients rather than display the energised state of a relay.
The module features a blue insulating housing and a plug-in construction suitable for selected Finder relay sockets designed to accept the 99.80 accessory format. This makes it a practical choice for electrical panel builders, automation engineers and maintenance professionals seeking a compact alternative to separately wired suppression components.

How RC Suppression Helps Protect AC and DC Relay Control Circuits
Relay coils are inductive components that store energy in a magnetic field while energised. When the control voltage is removed, the magnetic field collapses and can generate a voltage transient across the coil. Depending on the circuit arrangement, this transient may contribute to electrical noise, interference or increased stress on associated switching components.
The Finder 99.80.0.230.09 contains a resistor-capacitor suppression network designed to help limit these switching transients. The capacitor and resistor work together to absorb and dissipate part of the transient energy, reducing the magnitude of unwanted voltage disturbances.
Because the module is specified for 110–240 V AC/DC, it can be considered for compatible relay coil circuits using either alternating or direct current. This distinguishes it from freewheeling diode accessories, which are generally intended for correctly polarised DC circuits. The complete relay and socket assembly must still be checked for electrical and mechanical compatibility.
RC suppression may also influence relay release characteristics and can introduce a small current path under certain circuit conditions. For this reason, engineers should assess the connected control device, relay coil characteristics and any relevant off-state leakage requirements before selecting a suppression accessory.
The 99.80 plug-in construction allows the module to be fitted into compatible Finder relay sockets without separately mounting a resistor and capacitor assembly. This can simplify panel wiring and maintenance, provided the equipment is safely isolated before installation or replacement.
