Anybody knows the coil Ohm on this relay, or measure the coil Amps? I'm looking for something between the real starting relay, and the "40A" relay...

I always you the secondary lead for actuating the solenoid. You can use either side. Therefore I never had a need to know the ohm rating, sorry

Hi,We have both. The one you are looking at is 8 ohm. Thanks for asking and have a nice day.

Andy - I connected my contactor to a Variac and measured the coil current. I measured the following: Pull-in current 145mA to 155mA. Sustaining current 60mA. Drop out current about 30 mA. The solenoid buzzed really badly if the available current was LESS than 145 mA at pull-in, which leads me to believe that your problem is the output driver on the motion sensor can't provide enough current to pull the contactor in. You can measure the sensor output current to the contactor coil by CAREFULLY connecting a multimeter, set to the 10 amps AC scale, in series with your coil drive circuit, and monitor the amount of current it's putting out while the contactor buzzes. Be careful, 120 volts. If your driver can't provide the current to drive the contactor, one way around this would be to use a second, smaller relay to pull in the bigger contactor. Typical "ice-cube" 120v coil relays just require ~ 10-20 mA to pull in. Then this small relay's contacts could activate the coil of the larger contactor. If your motion sensor is providing the proper current then the problem may be related to noise, but I'd check your driver circuit's current capability first. Greg Walz greenlite350@aol.com

Mine burnt up or froze on the first test when used with an ac induction motor on a dust collector. The collector required a dedicated 15 A breaker. I thought the Additional 25 A rating would be plenty. I had to buy a crydom brand to get it to work. You are either looking for a relay that will handle a resistive load like a heater or an inductive load like a ac motor. This is not the relay for a motor.

Your best option is to grab the exact part number from the top of the coil pack. There are many variations. Need to buy the exact match. They are easy enough to remove and check. It should be under the plug if I remember correctly.

When we checked, the coil current is about 0.100 amps at 12 volts. They are quick and reliable.

Yes, I noticed that to when the first one arrived. I apologize but I have not had time to check it yet. I purchased several for use on a postwar Lionel model train layout to use as track block relays as noted from a 1956 Lionel manual. Please stay in touch and I will try to get you an answer. I also purchase some Huron HH52P relays and the coils are clearly marked "12V AC."

Question is a little vague, but: 110/120vac coil means just that. 110-120vac to turn on the relay. That said, most air conditioners use 26VAC on the coil voltage. The contact voltage & current ratings are:125vac 60amps resistive(not motor)250VAC 35 amps resistiveInductive (motors) Full Load125VAC 12 amps250VAC 6 ampshope this helps

What you need to know: The counter start when the unit receive power. You have two relays (N/O) and (N/C). / When the timer complete the cycle (120 seconds set) the N/C relay open and stay open until lose coil power (off). Now look how you design your circuit to supply power and when. The power to the coil is 12 volts DC. The current to relay can be your pump power (neutral or hot) not both. You need to purchase another part: NTE R95-113 8 Pin Octal Relay Socket with Screw Terminals $9.

I try them without load resistors, and it messed up my parking/stop lights. Had to take it to the dealer, charged me $86 bucks to fix. I just bought a relay.

It blew a fuse in my car at an end on inflating a first tire. I was adding 7psi. this was 30A fuse (2 sockets on this circuit). I returned it because of this event. I didn't want to experiment whether it was a single event or failure of this one inflator, or typical over-current.

"The relay contacts do not supply power. You use them as a switch for the power you wish routed through them" Same answer, no attitude. Cheers!

Im not sure how much current the relay draws since i haven't measured it, but i have run the relay with a 5V standard GPIO directly without any adverse effects. This is with a Sanguinololu 1.3a PCB used in 3d printers. Essentially an Arduino.

I'm not sure what do you mean by 40. But if you have a device or motor being wired got 220 volt one leg is always hot and the other one gets switched by the relay.Hope it helps.

If you looking at the same set I purchased, it' would be 10 amps? They come prewired with relays and all!!! Easy to wire up!! They send instructions. You may want to look at the different pictures to the left of the main picture. There is a diagram showing how to wire and how many amp it need to use. Hope this was helpful.

You have to use a "Shut" to wire across for the current to be measured. The voltage will be measured when connected to your source. I don't remember the wiring sequence, but it was spelled out in the instructions. If I remember correctly Yellow goes to the shut, Red - Source Positive, Black - Source Negative. You would need to double check my memory for accuracy.

Alan,Wish I could help. After spending an hour with my Fluke I wasn't able to figure it out. I spent more than an hour (no joy) searching for the wiring diagram before resorting to the Fluke.I ended up using only the AC IN jack - bypassing both pwr switch and fuse.Kind of a bummer. Good luck, man.Steve
