Finder 99.01.0.024.09 – 99 Series Modules for 90/92/94/95/96/97 Series sockets

Why Choose the Finder 99.01.0.024.09 RC Suppression Module?

The Finder 99.01.0.024.09 is a compact and reliable RC (resistor-capacitor) electromagnetic interference suppression module designed to reduce voltage transients and electrical interference generated by relay coils. As part of the Finder 99 Series coil indication and EMC suppression module range, it provides a practical solution for protecting industrial control circuits and improving electromagnetic compatibility in relay-based automation systems.

Featuring an integrated resistor-capacitor suppression circuit, the 99.01.0.024.09 helps absorb transient energy produced when an inductive relay coil is switched off. This reduces unwanted voltage spikes and electrical noise that could otherwise affect nearby control electronics, PLC interfaces and other sensitive automation equipment.

Designed for a 6–24 V AC/DC operating voltage range, this module is suitable for low-voltage industrial relay coil circuits. Its compact plug-in construction enables straightforward installation into compatible Finder relay sockets, including selected sockets from the 90, 92, 94, 95, 96 and 97 Series. The module's blue housing provides a practical means of identifying the suppression accessory within electrical control panels.

Reliable EMC Suppression for Industrial Relay Circuits

Electromechanical relay coils are inductive components that store energy in a magnetic field while energised. When the supply to a relay coil is interrupted, this stored energy can generate a voltage transient capable of producing electromagnetic interference or affecting nearby electronic control devices. The Finder 99.01.0.024.09 uses an integrated RC suppression circuit to help absorb these transients and reduce their impact on the electrical installation.

Unlike polarity-sensitive diode suppression devices, an RC suppression network can be used with compatible AC and DC relay coils. This makes the module a flexible solution for low-voltage industrial control applications. Its plug-in construction allows the suppression circuit to be fitted directly into a compatible Finder relay socket, reducing the need for separately wired suppression components.

Typical Applications

• Industrial relay coil transient suppression.
• PLC output and relay interface protection.
• Electrical control panels and switchboards.
• Machinery automation and switching systems.
• Low-voltage AC/DC relay control circuits.
• Building automation and equipment control systems.
• Industrial process control and manufacturing equipment.
• EMC improvement in relay-based control installations.
