Safety Instructions

Do not touch connections carrying voltages above 25 V/AC or 35 V/DC.

• Be especially careful when dealing with voltages higher than 25 V alternating (AC) or 35 V direct voltage (DC)! Even at these voltages, it is possible to receive a fatal electric shock if you touch electrical conductors.

Delivery Content

• Product

Description

Use the product to switch components integrated into your circuits that require high power. The circuits are optoisolated.
The module features 4 high-current rated relays:

• l 250 V/AC / 10 A
• 125 V/AC / 10 A
• 30 V/DC / 10 A
• 28 V/DC / 10 A

Each relay comes with a status indicator light. The board has a power indicator light. The board can be directly controlled through a micro- controller, including

• Arduino®, Raspberry Pi®, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic

Pinout / Pin Map

change the TTL mode(default: HIGH level).
NO| Normally Open Connection
NC| Normally Closed Connection
C| Middle pin: Common connection. Connects to load.

Note: There are no NO, NC, and C imprints on the product. Instead, observe the diagrams near the relay terminals.

Example Application

In this example, we will switch on and off two lights.
Each light comes with its own power supply as indicated in the diagram.
The left light connects to Relay 1 and the light on the right to Relay 4. In a real application, you may be switching a fridge, TV, or industrial appliance instead of battery-powered lights.
The instructions use the Arduino® platform to illustrate product use. You can also use an Arduino derivative or another platform that supports this type of product.
Connection
Control circuit:

Power circuit:

Code
#define RELAY1 6
#define RELAY4 7
void setup( ) {
// Initialise the Arduino data pins for OUTPUT
pinMode (RELAY1, OUTPUT);
pinMode (RELAY4, OUTPUT); }
void loop() {
// Turns ON Relays 1
digitalWrite (RELAY1,LOW);
// Wait 2 seconds
delay (2000);
// Turns Relay Off
digitalWrite (RELAY1, HIGH);
// Turns ON Relays 4
digitalWrite (RELAY4, LOW);
// Wait 2 seconds
delay (2000);
// Turns Relay Off
digitalWrite (RELAY4, HIGH); }
Procedure

1. Prepare a sketch with the given code and upload it to your board.
2. Connect the module/component to the board as shown in the connection diagram or table.
3. The relays are switched according to the settings in your code.
