OMRON H3Y-4 24VDC 3A 250VAC Timer Relay

Description

The OMRON H3Y-4 is a timer relay designed for controlling electrical devices in Arduino projects. It allows for the switching of circuits based on a command signal. Specifications: Supply voltage: 24VDC, Switching current: 3A, Switching voltage: 250VAC, Time delay: 60 minutes. Ideal for controlling 24VDC electrical devices in both domestic and industrial automation scenarios. Compatible with Arduino and ESP platforms. Tutorial: How to use H3Y-4 Connect the relay to a 24VDC power source. Connect the control signal to an Arduino digital pin. Connect the relay contact to an electrical device. Load the provided Sketch code. Test the relay with different control signals. Verify the relay stability after 60 minutes. 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 using a light sensor and H3Y-4 relay. Common errors: Connecting the relay to a power source with a voltage higher than 24VDC. Not verifying the relay stability after 60 minutes. Not using a logical control signal. Not using an analog pin for the control signal. Recommended accessories: Light sensor, Arduino UNO, connection cable, 24VDC power supply. Frequently asked questions: Can this relay be used with different voltages than 24VDC? Check the datasheet for compatibility with other voltages. How long can the relay function? The relay functions correctly for 60 minutes. What are the current limits of the relay? The relay can handle a maximum of 3A.
