Relay 1-Channel 12V Level Trigger Optocoupler Module diode Dimension: 76x54x19 (mm)/ 2One Channel Relay Board for 12V Control Systems The Relay 1 Channel 12V Level Trigger Optocoupler Module is a one channel relay module built for 12V 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
