Relay 1-Channel 9V Level Trigger Optocoupler Module optical fingerprint sensor no programming required (optional modularOne Channel Relay Board for 9V Control Systems The Relay 1 Channel 9V Level Trigger Optocoupler Module is a one channel relay module built for 9V class control systems that need a ready made relay output board instead of a raw relay component. It includes an optocoupler and standard NO COM NC relay terminals for easier integration. This is a useful option for control panels, industrial style logic, trigger circuits, and other builds where the
