Questions & Answers

It makes sense if I use this relay to control a 1500 watt oil radiant heater in greenhouse, and close the no relay with a signal from an Inkbird wireless temperature ?

I am satisfied as long as the relay is driven by 120v from the controller. A wattage of 1500 is also well within the range of the contacts for 30 amps.

In this enclosed power relay, does it matter which ends of the control hot and neutral lead to? (1 or 0)?

Some neutrals are switched in some cases, so the other leg of a 220volt circuit may be used in some circumstances. Look at your schematic and trace out line 1 and line 2. Indicator lights are usually the only lights that use the neutral.

Will it require a heat sink or will it be able to be mounted directly on a DIN rail without developing heat problems?

Unlike a heat sink, this does not require one. DIN rails can be mounted to the rails. The one I have is directly mounted to the outside of a project case, so I am unable to answer that question.

This case is made of high-quality injection molded plastic

5/5

A firm's industrial strength is its ability to produce goods. The toy in question isn't available at a hobby store. I found this relay to be very reliable The product was molded from plastic injections It is one solid and strong Because I did not think through my order, I ordered NC instead of NO. I did not get a chance to test it, but I appreciate the industrial design and build quality in I have a black turban, not a grey one.

That's great

5/5

The quality was excellent and the service was excellent as well. 2 of them are used in an electric beer brewing setup. I am not sure how long it will last after it cycles on/off, but it should be able to hold up for a while. About 2 months after I began using this relay, I had a coil fail. I'm not sure what happened, maybe my own fault. Just a heads up for anyone considering purchasing, you might want to have a spare.

This circuit is used to allow the switch to be used at 1 amp

5/5

It controls a 20 amp circuit to power a set of high power monoblock power amps on the basis of a 1 amp switched circuit in a preamp. It was the perfect fit for our needs.

I could not be happier

5/5

My exterior lights need to be controlled by a simple timer, and this gave me the power I needed.
