thc15 dc 12 v and the cn101 dc 12 v timer do they have there ownpower or can you use a external 12 v power are any of the timers double pole

I use a cn101 to control a diesel fired heater on a narrowboat. It is powered from the boat's 12v supply but maintains the correct time despite being isolated for long periods (weeks) so I presume it has a small rechargeable cell built in just to keep the clock going. I think it's only single pole,- not sure but it should tell you that in the product details.

I think that they have a small battery but that's just for the clock memory. The switched contact requires its own 12vDc power source.

I used a 12v battery ( which is charged from a solar panel,) to power the timer and the led strip lights. Works perfectly. Lights run 4 hours a day, timer is always drawing a small amount of power from the battery.

The timer is a pile of @#$*. The directions do not tell you polarity nor does the timer. I could not get it to work. Do not buy!

Works great ! The timer has an internal cell used to maintain the time base, but is meant to operate from an external 12 vdc power supply. The SPST relay can be wired to drive literally any size external relay or device (dpdt / 4pdt) etc.

You have to use an external 12v dc supply, not sure about the double pole ?

This unit will supply power, when triggered, for a time period that you can adjust. I use this to run a 12v dc motor, my trigger is a electronic timer that triggers this unit to run for a preset time. Hope this was helpfull.

The timer does not have pigtail leads for the input. It has two tabs (+ and -) so you can solder or use crimp-on female terminals to attach your wiring.

You could have them both connected to the same battery. Each has its own controller. I do not know if you can wire them for any configuration other than 12v....

Just found this out. If you go to the page on Amazon where they sell the relay and go down to the 5th photo there is a basic schematic. It shows that the pulse wire to active the relay is 12V+ which you need anyway to power the timer. One of the reviews also talks about this as one person wished the pulse could have been 12V- JW

Timer remembers the settings. There is an internal back-up power supply. Not sure how long it lasts, but I have not had to reprogram the timers. I have been very pleased with these timers. So far, the best I've ever purchased.

this is a terminal block that can handle 12 volts with no more than 8 amps of current if you replace the current wires that come with it.they look like they came out of a computer or plone block. you could also hook your devices to relays and use the block to supply voltage to the switch side of the relay.

I'm not sure, as we do not use ours on a timer. Sorry if this isn't helpful.

Not sure if you were trying get information about how to attach them to your motor or if it was a question about the device itself. Others have answered about the attachment. As far as the timer itself, the time advances as soon as a DC voltage is applied across its + and - terminals. The operating voltage can be 10 to 32 V DC. Timing stops when the voltage is removed. So it accumulates and holds the time that voltage has been applied to its terminals.

Hi, the switch you mean the contact? The timer power suplpy is 12vdc. But you can manage 12, 24, 110 v etc only taking care of your load.

This timer is used for 12 volt powered items only. It will not control 120 vac powered items. This timer controls things from a 12 volt vehicle battery.

Jack, This timer is strictly an ON/Off switch operated by a 12 Volt electronic clock. There are 2 terminals to power the clock & memory and 2 terminals for the single pole contacts.

Cristina, this 15-minute interval timer has only one outlet, an undesirable LED light, does not last long, and wobbles in the power outlet (cheap). I suggest a heavy duty mechanical timer from Home depot. It is a solid 30-minute interval timer with two outlets, no LED light, and lasts much longer than the TM01015.

According to the label on the wall wart that comes with the projector, the INput is 200mA @ 120V which calculates to 24 watts input maximum. The OUTput is listed as 6 vdc at 1.0 amp which calculates to 6 watts OUTput. Not much. I'm not sure what you want with a timer for . . . the unit has a timer internal set to 4 hours or so. It automatically shuts itself off. That information is available in the description on Amazon. I've had mine awhile now and still enjoy it.

Yes, it does. While minimal, It has a red LED that is powered when ever power is applied to the unit. You need to apply power to the unit in order to short the two leads. So for anyone hoping to use this with a battery, a typical 12v Red LED consumption is .01 amps. That's 1000 hours on a 10AH battery or 40 days. It's a shame, the device is great otherwise. The jumpers control the time. S4, S1 and S2 combined with the pot control time. There doesn't appear to be a jumper tied to the LED.

Hydrofarm TM01015D Dual Outlet Grounded Timer is the model which has two or "Dual" outlets, hence the "D" in the model #. Personally I'm going with something more industrial/heavy duty and running a power strip and lights on my kitchen sprout/veggie growing station, because it will be unattended for long periods and I don't want a fire or failure.
