Description

Features:1. The module uses genuine quality relay, normally open interfaces maximum load: AC 250V/10A, DC 30V/10A2. Using SMD OPTOCOUPLER isolation, driving ability, stable performance; trigger current 5mA3. The module voltage is 5V/9V/12 V/24V are available4. The module can be set to high or low triggered by jumper5. Fault-tolerant design, even if the control line is broken, the relay will not operate6. The power indicator (green), relay status indicator (red)7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient8. Module size : 50mm * 40mm * 16mm (L * W * H)9. Has four mounting bolts holes, hole 3.1mmInterface:1. DC+: Positive power supply (voltage required by the relay, there 5V/9V/12V/24V choice )2. DC-: Negative power connection3. IN1: 1 channel signal to trigger the end, you can set a high or low level control relay3. IN2: 2 channel signal to trigger the end, you can set a high or low level control relayOutputs:NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1COM1: 1 relay common interfaceNC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacantNO2: 2 -way normally open relay interface, the relay before floating, pull back and COM2 shortCOM2: 2 Common Interface relayNC2: 2 channel normally closed relay interface relay short front and COM2, pull vacant postHigh and low trigger selection:S1 as a relay trigger selection of high and lowS2 high and low for the two -way relay trigger selectionComes with low short circuit, triggering the corresponding relay is low, while the high end of the short com high triggerHigh and low trigger selection:Short jumper with LOW triggered when connectedWhen the jumper is high with high short triggerPackage includes:1 x 12V 2 channel relay driver module for
