1 CHANNEL 5V RELAY MODULE KY-019, JH ELEC. YXA044

Description

Relay coil driving voltage is 5V, the input control level may also be within 5V module description:

1. output driving ability: 250VAC-10A.125VAC-10A.30VDC-10A.28VDC-10A

2. easy to use, each set of output 3 line structure simple, reserved 6 output terminal;

3. input directly connected to the microcontroller IO port or digital circuit, the input high

level relay or absorption, low input level relay release;

4. working voltage is 5V,current 70mA every road ,With relay status indicator light

5. all SMT components, the most reasonable drive circuit design, driven by 8050 triode relay action;

6. has a fixed screw holes convenient installation, circuit board size is 1.8cm * 4.0cm * 1.9cm

1. New 5V Relay Module

2. can be used as microcontroller development board module can be used as home appliance control

3. 5 V-12V to TTL control signal

4. the control signal DC or AC , 220V AC load can be controlled .

5. there is a normally open and one normally closed contact

6. a power indicator light

7. a control indicator , pull off, disconnect does not shine

8. transistor drive to increase the relay coil control pins high impedance.

9. the control pin has a pull-down circuit to prevent malfunction relay vacant
