Control DC / AC signal, can control 220V AC load
One normally closed contact and one normally open contact
Triode drive, increasing relay coil

 High impedance controller pin
Pull-down circuit for avoidance of malfunction
Power supply indicator lamp
Control indicator lamp
Channel:1 channel
Main Color:Black + Blue
Relay Voltage:5V

5 v 1 road relay:
1, the module uses the genuine high-quality relay, normally open the interface maximum load: AC 250V/10A, DC 30V/10A;
2, use the patch optical coupling isolation, driving ability is strong, stable performance; Trigger current 5 ma;
3, the module operating voltage is 5V;
4, the module can set a high level or low level by jumper trigger;
5, fault tolerant design, even if the control line, the relay will not move;
6, the power indicator light (green), relay status indicator light (red)
7, human interface design, all interface can be directly by terminal connection leads, is very convenient
8, module size: 26mm* * 18.5mm 50mm (L * w * h)

The second module interface:
1, DC + : connect the positive power (voltage according to the requirements of relay, there are 5 v
2, DC-: negative power supply
3, IN: can be high or low level control relay and off
Relay output:
1, NO: the normally open relay interface, hanging relay, pull and COM short circuit
2, COM: relay common interface
3, NC: & have spent Before the relay and relay normally closed interface, and COM nipple, sucking the dangling after
