Great little timer relays. I have used 4 of these now and really like the way they work. So far, they have held up very well and I have had no issue with any of them.They are small, versatile (AC or DC voltage), mount to a piece of DIN rail, easy to wire and set, and they are reliable. Great to just keep one of these in your extra parts bin if you do any electrical work at all.

A very professional multifunctional time relay. Delay on time relay, delay off time relayand cycle relays and so many others are all here. It's worth the money.

This one isn't industrial quality at all (since it's only around $26) but it works ok.The default setting starts the timer as soon as you apply power to the input of the coil and A1 and A2..After the time expires it switches the output contact as it should.I had to read the manual for 5 minutes to get it going, there it is.The DC coil on the model GRT8-A2 needs 12V DC or more to run.The coil is on A1 and A2. A1 is positive. A2 shows negative next to the terminals.To reset the timer you can drop power or reset by applying + Voltage onto the terminal marked as "S"This model has a NC and Normally open contacts to pick from. One of each.It had a creative, very wide range of timing and LED indicators to show power ON and output ON.- My only complaint is the screws are small and somewhat soft/fragile.- Well, 2nd not a fan of the plastic DIN rail clips too with no metal spring.Other than that it runs as it should.

This on-delay relay worked perfectly as expected. I was able to use this relay to control a contactor running a pump that would short cycle without a delayed start. This on-delay timer functions perfectly for this application and consistently operates as expected. This delay relay can be set up for a wide range of on/off delays and time settings, making it an ideal solution for a wide range of applications.

I received this delay time delay relay and I am very satisfied with it.I need it to control the working time of my air conditioner. It has too much power and it will waste a lot of electricity if it is always on (one time I came home from get off work and found that the air conditioner was still on because I forgot that it worked all day), so I have to buy a device to control the working time of the air conditioner.I love all the options on this thing. It can have AC input,230V. Also, the timer setting adjustment can be set from 0.1 seconds to 10 days. In fact, since there is a 0 to 100% sub-range under the timer knob, you can set it from 0 to 100% of the timer setting (I usually set the air conditioner to work for 18 minutes, the timer knob is set to 1h, and the percentage knob is set to 30%, so that is 30% of 60 minutes, which is exactly 18 minutes, which saves me a lot of electricity).In addition, I browsed the seller's store and I think the products are very professional. There are many different models, and they have different functions and usage scenarios. I will buy from this seller again and recommend it to my friends.

I have always wanted to buy a device that can automatically control the opening of the shower water heater. I want it to open after 1 hour or 50 minutes, so that I can enjoy hot water after my outdoor fitness activities. I finally found it.Its name is GRT8-A1 AC DC12V-240V, (A stands for delayed opening, B stands for delayed disconnection. This seller has many models corresponding to different functions. It looks very professional, which is why I chose it). I set the first time knob to 1h and the second percentage knob to 80%. In this way, it will automatically turn on the water heater for me after 48 minutes. It is so convenient.

Connect it to the street light next to the apartment, so that the street light can be turned off automatically after it is turned on at night. Please, I used to turn it off in the morning by myself, and the distance between them was too far. It can be turned off automatically through this, which is great.

I integrated this relay into my water pump and it fills my water tank in about 30 minutes. Before, I forgot to turn it off and the water overflowed and there was water everywhere. The first time I tested it, I set it for one minute and turned on the pump. As a result, after 1 minute, it really stopped. This is amazing. It's great.After carefully checking the instructions, I found that it can be adjusted from 0.1 seconds to 10 days. What a wide time, and the relay is easy to mount on the DIN rail and the size is also small. It is a great choice for me.
