Applicable Load Suitable for AC or DC 5400V inductive loads up to 1000W. This RC absorption module is designed to protect relay contacts or thyristors from damage due to inductive switching. Protection Builtin varistor clamps voltage fluctuations and limits surge current to prevent relay contact adhesion and excessive wear. Function RC absorption circuit module that protects relays or thyristors from the inductive electromotive force produced when the load turns on or off. Reduces electromagnetic interference and helps improve the anti jamming capability of microcontrollers in mixed signal environments. RC Absorption Circuit Absorbs the induced electromotive force of inductive loads to smooth switching transitions and suppress voltage spikes. Key benefits Protects switching devices such as relays and thyristors from inductive voltage spikes. Minimizes contact adhesion and wear in relay contacts. Suppresses electromagnetic interference and enhances microcontroller reliability. Compatible with AC or DC inductive loads within the specified voltage and power range. Specifications and performance highlights Voltage compatibility: AC or DC 5400V Load type: Inductive Maximum load: 1000W Protection features: Varistor based, overvoltage and surge current suppression Function: RC absorption network to mitigate inductive EMF and EMI Applications and use scenarios Scenario 1: A relay controls a 12V DC motor or solenoid in an automation cabinet. The RC module protects the relay contacts from arcing and reduces EMI during on/off cycles. Scenario 2: A thyristor driven circuit in an industrial control panel switches an inductive load. The RC network helps prevent damage from voltage spikes and improves switching reliability. Scenario 3: A microcontroller based control system that drives inductive loads. The added RC absorption reduces EMI and improves system noise immunity, enhancing overall stability.
