ITEM NAME:1x 12V 1 Channel Relay Module Optocoupler High and Low Level Trigger JR A module description: 1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A; 2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; 3. the module voltage is 5V, 9V,12 V, 24V are available; 4. the module can be set to high or low triggered by jumper; 5. fault-tolerant design, even if the control line is broken, the relay will not operate; 6. the power indicator (green), relay status indicator (red) 7. interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient 8. module size: 50mm * 26mm * 18.5mm (L * W * H) 9. has four mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm pitch Two module interface: 1. DC +: positive power supply (voltage required by the relay, there 5V.9V.12V and 24V choice) 2. DC-: negative power connection 3. IN: can be high or low level control relay Relay outputs: 1. NO: normally open relay interface, the relay before the vacant after the pull shorted with COM 2. COM: Common Interface Relays 3. NC: normally closed relay interface relay shorted with COM ago, after the pull-vacant High and low level trigger selection ends: 1. When jumper short circuit with LOW is low lever trigger; 2. When jumper short circuit with high is high lever trigger..Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;. the power indicator (green), relay status indicator (red). NO: normally open relay interface, the relay before the vacant after the pull shorted with COM.
