10/5pcs 5V 1 Channel Relay Module With Optocoupler KY-019 1 Way For Arduino
1. Product Introduction
1) Working voltage: DC 5V
2) Relay control capability: 10A 250VAC/10A 30VDC
3) Effective high-level control
4) Pin Description:
+: Positive pole of power supply
-: Negative pole of power supply
S: Signal input
5) Relay interface description:
NC: Normally closed end
COM: Public end
NO: Constant Beginning
2. Main uses:
1) Expanding control range: When the control signal of a multi contact relay reaches a certain value, different forms of contact point groups can be contacted, and multiple circuits can be replaced, turned on or off, and connected at the same time.
2) Amplification: With a very small control quantity, it is possible to control the on/off of circuits with high power.
3) Integrated signal: When multiple control signals are input into a multi winding relay in a specified form, they are compared and synthesized to achieve the predetermined control effect.
4) Automatic, remote control, detection: The relays on the automatic device, together with other electrical appliances, can form a program control circuit to achieve automated operation.
1. The relay acts as a switch, used to control the on/off of the load circuit, and is a passive output (non energized output).
The voltage and current allowed to be loaded by a relay determine the magnitude of the voltage and current that the relay can control. When in use, this value should not be exceeded, otherwise it is easy to damage the contacts of the relay.
