Relay Module (1 Channel) Active Low Trigger 12V HW-307

The module is equipped with relay 12V with coil powered with a voltage of 12 V. The systems allows you to control actuators with microcontroller ports or with any implementation set. Works with voltage up to 250 V. Specification The supply voltage VCC: 12 V The switching state of the relay via low state Relay 12V Coil voltage: 12 V The maximum voltage of contacts: 250 VAC, 125 VDC* Maximum current: 10 A for 250 VAC 10 A for 125 VAC Tile sizes 43 x17 mm Description The module allows to control the actuators consuming the current up to 15 A with microcontroller’s ports or with any implementationset (including Arduino). For proper operation, it is sufficient to connect the power of the relay and the digital control signal. Leads are the standard strip goldpin with pitch 2.54 mm which enable to connect via connecting cables. Examples of application Driver of lighting The driver of actuators Switch for electric devices, including motors Connection The module has four input / output VCC, GND, IN . To work correctly, you must connect the power supply 12 V to the VCC pin, mass GND and the input signal IN. Indicating the low state (the potential of the mass) switches the relay contacts. Disabling the IN lead or indicating the high position, switches the relay to its initial state. Providing low sttae, switches the contacts of relay and makes the connection between the COM (the middle contact) and NO, seperates COM and NC. This operation is also signaled the illumination of the green led.
