❥For AC or DC 5 ~ 400V inductive load (less than 1000W), protection relay contacts or thyristor. For AC or DC 5 ~ 400V inductive load (less than 1000W), protection relay contacts or thyristor. ❥RC absorption circuit module used on protecting the relay or thyristor because it can avoid damage that from inductive electromotive force generated by the inductive load when on or off. Preventing electromagnetic interference and increasing the anti-jamming capability of the microcontroller. ❥RC absorption circuit,absorb induced electromotive force that from inductive load. To provide anti-interference ability of the circuit. ❥Instructions for use: This module is suitable for circuits containing inductive loads and switching devices such as relays and thyristors. When used, the two connectors of the module connect to two contacts of the relay, or parallel with the thyristor, to avoid induced electromotive force damage the relay or thyristor. ❥Package include: 1 x RC Absorption/Snubber Circuit Module
