Keyestudio Four-channel Solid State Relay Module
Introduction
Keyestudio four-channel solid state relay is a high level effective solid state relay, that is to say, the input control signals is the low level (0-2.5 V), the relay is off; while the input control signal is high level (3.3-5 V), the relay is on.
Solid State Relay is a new kind of contactless switching device which is composed of all solid state electronic components. Compared with the electromagnetic relay, its reliability is more higher, with the features of non-contact, long service life, fast and less outside interference.
The output control terminal of the keyestudio solid-state relay must be connected to the circuit, and its working current needs to be bigger than 50mA, so that the solid state relay can be disconnected normally.
Performance Parameters
- Electrical parameters:
Voltage | Static Current | Working Current | Trigger Voltage | Trigger Current | |
---|---|---|---|---|---|
Channel 1 | DC 5V | 0mA | 12.5mA | 3.3-5V | 2mA |
Channel 2 | DC 5V | 0mA | 12.5mA | 3.3-5V | 2mA |
Channel 3 | DC 5V | 0mA | 12.5mA | 3.3-5V | 2mA |
Channel 4 | DC 5V | 0mA | 12.5mA | 3.3-5V | 2mA |
- Output port : AC240V/2A
Connection Diagram
Sample Code
int BASE = 3 ; //The first relay I/O port int NUM = 4; //Total number of relay void setup() { for (int i = BASE; i < BASE + NUM; i ++) { pinMode(i, OUTPUT); //Set the digital I/O port to output } } void loop() { for (int i = BASE; i < BASE + NUM; i ++) { digitalWrite(i, HIGH); //Set the digital I/O port outputs to "HIGH", that is, gradually open delay(200); //delay } for (int i = BASE; i < BASE + NUM; i ++) { digitalWrite(i, LOW); //Set the digital I/O port outputs to "LOW", that is, gradually close relay delay(200); //delay } }
Result
Wiring as the above image,after powered-on,four-channel solid state relay is first connected and then broken successively,repeating alternately.
