RC absorption loop module relay contact protection circuit/electromagnetic anti-interference module

RC absorption circuit module relay contact protection circuit/electromagnetic anti-interference module

Module features:

RC absorption circuit, also known as RC buffer circuit, is a circuit structure in which resistors and capacitors are connected in series and in parallel with switching devices, used to improve the voltage and current waveforms that electronic power devices can withstand when turned on and off. The RC absorption circuit module can prevent the induced electromotive force generated at the moment of inductive load connection and disconnection from causing damage to switching devices such as relays and thyristors, prevent electromagnetic interference, and increase the anti-interference ability of the microcontroller.

Product Parameters:
1. Suitable for AC or DC 5-400V inductive loads (loads less than 1000W) to protect relay contacts or thyristors.
2. RC absorption circuit, absorbing the induced electromotive force of inductive loads
3. There is a varistor to prevent excessive voltage fluctuations and current from causing relay contacts to stick together.
4. Provide anti-interference capability of the circuit.
5. Using crimping terminals makes wiring more convenient.

Board Function Description:
Instructions for use: This module is suitable for circuits containing inductive loads and switching devices (such as relays and thyristors). When in use, the two interfaces of the module are connected to the two contacts of the relay (such as the relay and the common terminal and the normal terminal), or in parallel with the thyristor to avoid damage to the relay and thyristor caused by induced electromotive force.
