Description
The 12-volt 4-channel relay module is designed to control four power loads via Arduino or other controllers.
To use the relay module, you need to connect a controlled device to it. Then you need to connect 12V power to the Vcc and Gnd terminals of the module. After that, you can connect a microcontroller, computer or other control device to the control terminals IN1-IN4 of the relay module and start working.
The relay module has two interfaces - for connecting the control microcontroller and for connecting controlled devices to the relay. A 6-pin connector is used to connect the relay module to the control device. Contacts GND and VCC for connecting the supply voltage 12V, terminals IN1-IN4 for connecting the control signal.
To connect the load to the relay, there are 12 screw contacts on the board, 3 for each relay.
The relay module can be powered exclusively from external power sources.
Specifications:
relay operating current: 10 - 15mA (each)
relay supply voltage 12V
relay SRD-12VDC-SL-C AC250V 10A
overall size: 49 x 51 x 18 mm.
