["brand new and high quality\r\n\r\nFeatures:\r\nRC 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.\r\nFor AC or for DC 5 ~ 400V inductive load (less than 1000W), for protection relay contacts or thyristor.\r\nRC absorption circuit,absorb induced electromotive force that from inductive load.\r\nWith varistor, to prevent excessive fluctuations in voltage or current is too large and resulting in relay contact adhesion.\r\nTo provide anti-interference ability of the circuit.\r\nAdopt crimp terminals that make wiring become more convenient.\r\nInstructions 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.\r\nRC Absorption/Snubber Circuit Module only, other accessories demo in the picture is not included!\r\n\r\nSpecification:\r\nDimensions: 3.1x1.3cm/1.22x0.51inch\r\nQuantity: 1 Pc\r\n\r\nPackage includes:\r\n1 x RC Absorption/Snubber Circuit Module (without retail package)"]
