Contacts: Relay module has a set of 30A normally open + normally closed, dry contacts (ie isolated from the input).
Parameter: One way relay expansion module with optocoupler isolation operating voltage is 12VDC,operating current is 80mA.
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 controls high-voltage and high-current, especially suitable for 51 single-chip microcomputer expansion to control equipment work.
Large Load Capacity: Relay module adopts optocoupler isolation, strong driving capability, stable performance,which has large load capacity and the maximum load current is 30A.
Input: Active at low level (0V),the minimum drive current of 0.5mA is required.
