Specification: Item Type: Relay Module Operating Voltage: 12VDC Operating Current: 80mA Contacts: A group of 30A normally open + normally closed (isolated from the input) Input: Low level (0V) active, require drive current at least 0.5mA Function: When the input is low level, the relay is closed; when the input is high level or disconnecting (floating), the relay is open. It is mostly used for circuits in which small signal controls high-voltage and high-current, especially suitable for 51 single-chip microcomputer expansion to control equipment work Package List: 2 x Relay Module
