Hi,
Here is my schematic.
I don't know the exact implementation of the opto-isolated relay, so I left it dangling. I assume there is a resistor between the opto-diode and the Arduino's output (If anyone knows otherwise please say so). Notice that the opto-isolated relay uses the same 5V and GND...
Hi,
I have a project to control my water heater remotely. I bought a simple relay from DX () and for testing purposes connected the system to a 60w 220V light bulb and all worked well.
Since my water heater is 2.1KW I've decided to use 2 level switch, the arduino will turn on the relay and the...
Hi and thanks for your replay,
It seems that crydom do recommend zero crossing for resistive load, and they even claim that zero-crossing is the most common relay type for resistive heaters.
Link : **broken link removed**
Any idea why?
I'm designing a remote controlled switch for my water heater and I am bothered by the following questions:
1. Should the switch be DPST, or can I just switch the phase line (dangerous?) ? can I do it by using 2 SPST with the same control signal instead of a DPST?
2. Can anyone recommend a relay...
Hi all,
Im running a parametric sweep on Vdd on adexl, and I would like to correlate a period for each Vdd on the sweep. For example: vdd = 0.6; T = 100n and so on, my question is : is there a way to correlate parameters like that, some sort of a table or do I have to run these damned nested...
Hi all & thanks for all of the answers.
I find pavel's to be very helpful. Freebird, I am interested to know, if Im obliging on a certain clock frequency to the system, how low the Vdd can go, hence the using the filtered method I can actually calculate the yield...
Hi,
The expression is : (cross(clip(VT("/CMOS_NAND3_OUT") 1.27e-06 1.28e-06) (VAR("vdd") / 2) 1 "falling" nil nil) - 1.275e-06)
thanks, any help is appreciated
Hi all,
Im running a monte carlo simulation on virtuoso IC6.1.3.500.18. Im using the "clip" and "cross" functions in order to calculate fall time, and it works fine when I use vdd = 0.6 V, when I lower my vdd to 0.3 V the voltage does not drop to the defined cross value, hence the calculated...
Hi all,
I have this strange error, that just keeps popping once in a while. I create a schematic, and then I simulate it on adexl. after some simulations Ill get a warning saying "Could not find state...
Hi all,
Im trying to set voltage parameters for a vpwl source.
what I would like to do is to set the voltage to a sum of 2 other parameters that I have, IE : Voltage 1 = vdd + delta. When I try to simulate it using spectre Im getting a netlist error, any idea how it should be done ?
another...
