5PCS 12V 4 Channel Relay Module With Optocoupler Isolation Supports High and Low Trigger Road RM003 | Электроника

 

Module features: 1, the module uses genuine quality relay, normally open interface maximum load: AC 250V/10A, DC 30V/10A; 2, SMD optocoupler isolation, strong drive capability, stable performance; trigger current is 5mA; 3.Each module can be set high level or low level  trigger by jumper; 4, fault tolerant design, even if the control line is broken, the relay will not act; 5, the power indicator (green), 4 way relay status indicator (red) 6, the interface design humanization, all the interfaces can be connected directly through the wiring terminal, very convenient 7, module size: 73mm * 50mm* 18.5mm 8, with 4 fixed bolt hole, hole 3.1mm, spacing 67mm*44.5mm     Module interface:   1, DC+: the power supply cathode   2, DC-: the negative power supply   3, IN1-IN4: according to each channel's settings, can be high or low level control the corresponding relay's pull     Relay output: there are 12 wire interface, all the interfaces can be directly connected to lead, user-friendly.   1, NO1--NO4: normally open relay interface,  relay  suspended  before pull,after the pull  shorted with COM  2, COM1--COM4 relay common interface 3, NC1--NC4: relay normally closed interface,before pull the relay and COM short circuit,after pull the relay   suspended     High and low level trigger select:   1.S1-S4 in turn is the relay 1 way -4 way high and low level trigger selection;   2.When the com is short circuit to the low, the corresponding relay is  low level triggered. When the com is short circuit to the high terminal, the high level trigger
