DOUBLER SOLENOID DRIVER DOWNLOAD

This LC network of L 2 and C 4 provides enough smoothing so that the half wave signal being applied to the 24 VAC coil L 3 of the solenoid valve 17 b does not chatter. All references to current flow in the following description are references to flow of conventional current. Customer wanted to add zones on a new system we ran extra wires but ended up one less that needed. There’s a problem loading this menu right now. The valve next to it is OK, three valves in the box, so i know the common is alright. Amazon Second Chance Pass it on, trade it in, give it a second life.

This field needs to be dissipated and controlled, otherwise it might pass back through the triac and cause spikes on the conductor For equal switching times it is important to be able to maintain solenooid switching currents. The low gate current triac is preferably capable of switching with gate currents as low as 5 mA.

The method and apparatus solenoic allowing only the positive going voltage from one power supply to reach one load while blocking the negative going voltage from the one power supply reaching the source conductor.

Apparatus as claimed in claim 2 wherein the turn-off delay circuit comprises from each output to common, an LC snubber circuit.

The turn-on delay implemented in the decoder circuit 13 provides a soft start mechanism so that the two valves being controlled don’t electrically change quickly and hence this limits inrush current and the chances of the electronic fuse in the controller from tripping. Power distribution apparatus comprising relay devices for controlling current flow along power paths of the power distribution apparatus. Include Add a Protection Plan: Log in or Sign up.

This solution was very straight forward to install and the directions were accurate.

Apparatus as claimed in claim 1 wherein the first turn on delay timer to time out a predetermined period before operating said first switching circuit and the second turn on delay timer to time out a predetermined period before operating said second switching circuit are each a transistor based RC doublwr circuit. The apparatus has an encoder circuit 11 with two inputs 21 a 21 b for connection to the two AC sources, and an output 23 for connection to the single conductor 25and a decoder circuit 13 having an input 27 for connection to the conductor 25and two outputs 29 a 29 b for connection to loads 17 a 17 b respectively.

Apparatus as claimed in claim 1 wherein the first switching circuit and the second switching circuit each use a low gate current triac. Apparatus as claimed in claim 1 wherein the first turn on delay timer and the second turn on doibler timer each provide a turn on delay of at least 0.

Yes, my password is: The following discussion of the solenoi art is intended to facilitate an understanding of the present invention only. Dohbler always wondered if my guess as to what was inside one was accurate.

While the turn on delay could be longer, this increases the time that an output may not be operating, which in an irrigation application may interfere with normal operation, especially if there is high pressure trip out protection, doublet example.

Warranty & Support

The decoder circuits 13 a and 13 b overcome problems encountered with modern controllers that incorporate diagnostics and fault over-ride features, which can be falsely tripped by prior art devices, leading to faulty operation. In a preferred embodiment, the encoder circuit 11 comprises a pair of diodes 33 a and 33 b.

Circuit system for connecting an electrical consumer with an alternating-voltage source. Conversely, this method and apparatus comprises allowing only the negative going voltage from a second power supply to reach a second load while blocking the positive going voltage from reaching the source conductor.

If we can’t fix it, we will send you an Amazon e-Card reimbursement for your product purchase price. I wouldn’t mind seeing a photo of a dead doubler cut open.

While the turn off delay could be longer, this would increase the probability of two outputs being operational at the same time, which could interfere with operation of a reticulation system, especially where there is low pressure monitoring and trip out. It should be appreciated that the scope of the invention is not limited to the embodiment described herein. I get an open line on the ohms reading at the clock when the doubler is connnected both stations.

It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was part of the common general knowledge as at the priority date of the application. In accordance with a third aspect of the invention there is provided, an irrigation system solenoid operated valve control circuit, said control circuit having an input connecting to a half wave rectifier having a half wave rectified output, said half wave rectified output leading to a switching circuit interfaced with a turn on delay timer to time out a predetermined period before operating said switching circuit on said half wave rectifier passing current at an operational voltage, the output of the switching circuit connecting to an output for connecting to a solenoid of said solenoid operated valve, where the output includes associated therewith a turn-off delay circuit.
