How do I set the time delay on the GEYA GRT8-A2 relay?

You can set the time delay directly through the panel knob on the relay. The time scale is adjustable from 0.1 seconds to 10 days, divided into 10 distinct ranges, allowing for intuitive and precise setting of your desired delay.

What voltage range does the GEYA GRT8-A2 relay support?

This relay supports a wide voltage range, including AC/DC 12-240V and specifically AC230V, ensuring compatibility with various power systems commonly found in India and internationally.

Can I use this relay for both turning a device ON and OFF after a delay?

Yes, the GEYA GRT8-A2 relay has two optional function modes: 'A' for Delay ON, where the output activates after the set delay, and 'B' for Delay OFF, where the output deactivates after the set delay. This provides flexibility for various control scenarios.

How to buy an original GEYA GRT8-A2 single function delay on timer relay in India?

To buy an original GEYA GRT8-A2 relay in India, purchase from authorized US retailers and authorized brand partners like CrowCrowCrow. Products are imported per order, factory-sealed, and all customs duties and GST are included in the listed price. Delivery is via ExpressBox tracked service within 12-14 days.

What is the current rating of the GEYA GRT8-A2 relay?

The GEYA GRT8-A2 relay has a maximum switching current rating of 16A, making it suitable for controlling a variety of loads within this capacity. It also features two sets of output contacts, either 1SPDT (1NO1NC) or 2SPDT (2NO2NC).

Why choose this product

Engineered for Precision Timing

The GEYA GRT8-A2 relay is built for accuracy, offering a wide and adjustable time range from 0.1 seconds up to 10 days. This precision is crucial for applications where exact timing prevents equipment damage or optimizes energy use, such as controlling pump run-off times after a cycle or ensuring fans operate only when needed. Unlike basic timers, its dual output contacts and selectable modes provide flexibility for complex control circuits. Imported directly from authorized US retailers, this unit ensures you receive a genuine product built to international standards, all customs duties and GST are included in your price.

Ideal for Automation & Control

This relay is perfect for electricians, automation engineers, and advanced DIYers setting up control systems for pumps, fans, lighting, or machinery. It's particularly useful for applications requiring a timed delay after a signal is received. However, if your project requires a programmable timer with multiple independent schedules or a relay with a higher current rating than 16A, you might need to explore more advanced multi-function or power relays.

How to use

Mount the Relay — Securely attach the GEYA GRT8-A2 relay to a standard 35mm DIN rail within your control panel. Ensure it is firmly seated and aligned with other modules for a stable installation.
Wire the Connections — Connect the power supply (AC230V or AC/DC 12-240V) to the appropriate input terminals. Wire the control input and the output contacts (1NO1NC or 2NO2NC) according to your circuit diagram for the load you wish to control.
Set Time and Mode — Select the desired function mode (Delay ON 'A' or Delay OFF 'B') and adjust the time scale using the panel knob and range selector. Refer to the 10 ranges provided (0.1s to 10 days) to set your precise delay requirement.
Test the Operation — Apply power to the relay and trigger the control input. Observe the LED indicator and verify that the output contacts switch according to the set time delay and function mode. Make adjustments as needed.

Example scenarios

Typical situations where GEYA GRT8-A2 Single Function Delay On Timer Relay AC230V helps — illustrative scenarios, not customer reviews.

Scenario 1

Illustrative example

Where it helps

Controlling a pump's run-off time after a water tank fills.

How this product helps

Set the GEYA GRT8-A2 to Delay OFF mode. Once the water level sensor signals the tank is full, the relay activates the pump, and then automatically switches it off after the programmed delay (e.g., 5 minutes) to ensure the tank is completely drained and prevent pump burnout.

Scenario 2

Illustrative example

Where it helps

Automating ventilation in a small workshop or server room.

How this product helps

Use the Delay ON mode. Connect a temperature sensor to trigger the relay. When the temperature exceeds a set threshold, the relay activates the fan after a short delay (e.g., 30 seconds) to allow initial heat dissipation, ensuring consistent airflow when needed.
