Solid State Relay SSR-25DA 25A /250V 3-32VDC 250V

Description

What is a Solid State Relay (SSR) The SSR-25DA is an electronic device designed to control electrical circuits with a small control current. It is commonly used in Arduino projects and other automated systems to protect and manage electrical devices. Features Control voltage: 3-32VDC Maximum current: 25A Operating voltage: 250V Physical dimensions: 60*45*23mm What can it be used for Solid State Relays like the SSR-25DA are ideal for projects requiring the management and automation of electrical circuits. You can use it to create an automatic lighting system by connecting the relay to an electrical switch and a lamp, and using a light sensor and an Arduino to control the switch. How to use SSR-25DA The SSR-25DA is ideal for automating electrical circuits, serving to protect and control electrical devices with a small digital signal. Useful for beginner and intermediate makers. What is needed Arduino or microcontroller Power cable 250V Signal cable 5V Steps 1. Check the voltage compatibility between the relay and the microcontroller. 2. Connect the VCC of the relay to the 5V of the Arduino. 3. Connect the GND of the relay to the GND of the Arduino. 4. Connect the control pin of the relay (COM) to a digital pin of the microcontroller. 5. Connect the CO of the relay to an electrical device to control. 6. Connect the NO of the relay to the electrical device. 7. Check the relay response times in the datasheet. 8. Load a simple sketch to test functionality. Example code “` void setup() { pinMode(2, OUTPUT); } void loop() { digitalWrite(2, HIGH); delay(5000); digitalWrite(2, LOW); delay(5000); } “` Mini-project Create an automatic lighting system. Connect a relay to an electrical switch and a lamp. Use a light sensor and an Arduino to control the switch. Common errors Connecting VCC to 3.3V instead of 5V. Omitting the GND connection. Connecting the control pin to 25V instead of 5V. Ignoring the relay response times.
