LED module + diode 6...24V DC 99.02.9.024.99

Signaling and EMC Module – Protection of Power Circuits

This module, catalog number 99.02.9.024.99, combines circuit status signaling with basic electromagnetic interference (EMC) protection. It is a compact solution designed for mounting on sockets of the 95.03 and 95.05 series, as well as on DIN rails or panels. This makes it suitable for both professional and home applications.

This module is particularly useful in circuits powered by direct current (DC) in the range of 6 to 24V. Equipped with a green LED and a suppression diode, it provides visual information about the circuit status and protects against overvoltages that could damage connected devices. The LED indicates the presence of voltage on the relay coil, and the suppression diode protects against the effects of reverse polarity or inductive surges.

Functionality and application

This module finds wide application in building automation, control systems and anywhere where circuit status monitoring and protection against interference are required. It is ideal for protecting sensors, controllers and other sensitive electronic components. Thanks to its versatility, it can be used in both industrial installations and household appliances.

It is worth paying attention to the specifics of the suppression diode – its task is to short-circuit voltage pulses with reverse polarity, protecting the circuit from damage. However, it should be remembered that the relay release time may be extended (approximately threefold), therefore in time-critical applications it is recommended to use additional protective elements, such as a varistor or RC circuit.
