H3CR-A8 Time Relay is a specific model within the H3CR-A series of time-delay relays manufactured by Omron, a leading brand in industrial automation and control systems. This relay is designed for precise timing control in various applications, offering multiple timing modes, a user-friendly interface, and reliable performance. It is commonly used in industrial machinery, HVAC systems, motor control, lighting control, and other automation tasks.

Key Features:

1. Multiple Timing Modes:

• On-Delay (Delay-on-Make): Activates the output after a set delay when the input signal is applied.

• Off-Delay (Delay-on-Break): Deactivates the output after a set delay when the input signal is removed.

• Interval (Single Shot): Provides a fixed duration of output after the input signal is applied.

• Flicker (Repeat Cycle): Alternates between on and off states at set intervals.

2. Wide Timing Range:

• The H3CR-A8 offers a broad adjustable timing range, typically from 0.1 seconds to 120 hours, making it suitable for both short and long timing requirements.

3. Compact and Modular Design:

• The relay is compact and designed for easy installation on DIN rails, making it ideal for use in control panels and industrial enclosures.

4. Wide Voltage Range:

• It supports a variety of input voltage levels, including 24V DC/AC, 100-120V AC, and 200-240V AC, making it adaptable to different electrical systems.

5. LED Indicators:

• Equipped with LED indicators to display the status of the relay, such as power supply, timing in progress, and output activation.

6. Durable Construction:

• Built to withstand harsh industrial environments, the H3CR-A8 is resistant to vibration, shock, and electrical noise.

7. Easy-to-Use Interface:

• Features a rotary dial for setting the timing parameters, allowing for precise and straightforward configuration.

8. High Repeat Accuracy:

• The relay provides high repeat accuracy, ensuring consistent and reliable performance in timing operations.
