Finder 99.80.0.024.98 Relay Coil Suppression Module – 24 V DC
The Finder 99.80.0.024.98 is a compact plug-in relay coil protection and suppression module from the Finder 99 Series. Designed for use with compatible Finder relay sockets, it provides an accessory-based solution for managing electrical transients associated with relay coil switching in industrial automation, machinery control and electrical control panel applications.
Relay coils are inductive loads. When a coil is de-energised, the collapsing magnetic field can generate a voltage transient that may affect nearby electronic equipment or place additional stress on the device controlling the relay. A correctly selected suppression module can help manage these effects and improve the electrical behaviour of the control circuit.
The Finder 99.80.0.024.98 belongs to the low-voltage DC relay accessory range and is intended for a suitable 24 V DC control application. Its plug-in construction provides a convenient alternative to installing a separate suppression component across the relay coil wiring.
For electrical panel builders, automation engineers and maintenance technicians, this type of accessory offers a practical way to incorporate coil protection into a modular relay installation. The exact suppression characteristics, connection polarity and socket compatibility must be confirmed against the manufacturer's technical documentation before installation.

Technical selection note: The exact internal circuit and full electrical ratings for part number 99.80.0.024.98 should be checked against Finder's current technical documentation before this listing is used as an installation specification. The module must not be treated as interchangeable with other 99 Series accessories solely because they share a nominal voltage.
Why Relay Coil Suppression Matters
An electromechanical relay uses a coil to create the magnetic force required to operate its switching contacts. When voltage is applied to the coil, current flows and the relay changes state. When the control voltage is removed, the magnetic field collapses and the stored energy must be dissipated.
Without suitable transient management, this stored energy can produce a relatively high voltage across the coil or the switching device controlling it. The effect can be particularly important where a relay is operated by a transistor output, a programmable logic controller or another electronic control device.
A correctly specified suppression accessory provides a controlled path or voltage-limiting mechanism for this energy. The precise behaviour depends on the internal components used in the module.
Common suppression arrangements include diodes, diode-and-Zener combinations, varistors and resistor-capacitor networks. These technologies are not electrically identical. They differ in their voltage-clamping characteristics, polarity requirements and effects on relay release time.
For that reason, engineers should confirm the actual circuit used in the Finder 99.80.0.024.98 before selecting it for a design. The appropriate suppression method must match the coil voltage, driving device and required switching response.
Designed for 24 V DC Relay Control Applications
24 V DC is widely used in industrial control equipment, including PLC systems, machinery interfaces, sensors and auxiliary control circuits. A relay coil operating from this supply may be energised and de-energised repeatedly during normal equipment operation.
In such systems, the relay's electrical behaviour must be considered alongside the characteristics of the electronic output driving it. A suppression module can form part of the overall protection strategy.
The Finder 99.80.0.024.98 is intended for a suitable low-voltage DC relay application, but its exact operating limits must be verified. A nominal 24 V marking should not be interpreted as permission to connect the module to any supply described as 24 V without checking its permissible voltage range and electrical characteristics.
Where polarity-sensitive suppression is used, reversing the DC connections may prevent correct operation or cause an electrical fault. Installation should always follow the wiring diagram supplied for the exact module and compatible socket.
Understanding the Effect of Suppression on Relay Release Time
One important consideration when selecting relay coil suppression is the effect it can have on the relay's release characteristics.
Some suppression circuits allow the magnetic energy stored in the coil to decay relatively slowly. This can increase the time taken for the relay contacts to return to their de-energised position. Other suppression arrangements allow a higher transient voltage and can provide a faster release response.
The correct choice depends on the application. For example, a general-purpose auxiliary relay may have different switching requirements from a relay used in a tightly timed control sequence.
Designers should therefore check both the electrical protection requirements and the mechanical switching behaviour of the installed relay. The Finder 99.80.0.024.98 should be selected according to its verified suppression characteristics rather than nominal voltage alone.
Relay suppression accessories are not substitutes for certified safety functions, contact monitoring or protective devices required by the installation.
Plug-In Installation with Compatible Finder Relay Sockets
The modular Finder relay accessory system allows selected indication and suppression modules to be fitted to relay sockets designed with a corresponding accessory connection position.
This arrangement can simplify panel construction by locating the suppression component close to the relay coil connections. It can also make maintenance more convenient because the accessory can be identified and serviced as a separate component.
Before installing the Finder 99.80.0.024.98, confirm that the relay socket accepts this exact accessory type. Compatibility cannot be established from the Finder 99 Series designation alone, as different socket families use different accessory formats.
The electrical supply must be safely isolated before installation or removal. The module should be fitted in the correct orientation, and any polarity requirements must be followed.
After installation, the complete assembly should be checked against the relay manufacturer's specifications and the requirements of the control circuit.
