[[ADAM SYEX]] 8 relay module with high level trigger 12V optocoupler isolation support 12V One module description:1, the module uses the quality of high quality relay, normally open the interface of the maximum load: AC 250V/10A, DC 30V/10A;2, SMD optocoupler isolation, drive capability, stable performance; trigger current 5mA;3, module operating voltage is 5V, 9, 12V, 24V can be used to choose;Each module can be set to 4, high level or low level by jumper trigger;5, fault tolerant design, even if the control line is broken, the relay does not move;6, power indicator light (green), 8 way relay status indicator (red)7, the interface design of humanity, all of the interface can be directly connected through the terminal connection, very convenient8, module size: 50mm* * 18.5mm 141.5mm (length * width * height)9, with 4 fixed bolt holes, hole 3.1mm, spacing 136mm*44.5mm Two module interface:1, DC+: the power supply cathode (voltage by the relay requirements, there are 5V.9V.12V and 24V selection)2, DC-: the negative power supply3, IN1-IN8: according to each set can be high or low level to control the corresponding relay Relay output:There are 24 wire interface, all the interface can be directly connected to lead, to facilitate users to use1, NO1--NO8: normally open relay interface, suspended relay before and after COM shorted pull2, COM1--COM8: relay common interface3, NC1--NC8: normally closed interface relay, relay and COM short circuit, when suspended High and low level trigger selection: 1.S1-S8, in turn, the high and low level trigger selection of relay 1 way -8; 2.com and low short circuit, the corresponding relay for the low level trigger, high and com end of the short circuit for the high level trigger
