Thanks for your replies Brian, Klaus & asdf. Your answers were really helpful. Looking at the data sheets, almost all of the ratings of SMD match with THM. Brian & asdf thanks for sharing your knowledge on heat sinks.
Hi, Hope you all are doing good,
Say I have a PCB, a through hole one and i want to convert the same into SMT using as much SMD's as possible. Now the question is, are series & parallel passive component values same for SMD's? For example, if i used a 330 Ohm resistor in series with a LED to...
Yes. That was the problem. I increased the power rating of transformer & everything is fine. Thanks for your help. I appreciate it.
c_mitra, Yes the relay coils are protected.
Wow! I didn't thought of that, currently i am using a 500mA transformer-->Diode Bridge-->Vtg Regulator for 2 ATMEGA's, a ULN, 12 LED's & a few other components. Now i too think there isn't sufficient power. Will upgrade the transformer & update you soon.
Thanks andre_teprom & c_mitra :)
Hi,
I have this PCB on which there are 7 relays adjacent to each other. They may be on all at a time or may be some of them on others off or maybe all of them on. The problem is, when i turn on 3 relays, the 4th one doesn't turn on. but as i turn off the 3rd relay, 4th one turns on. Also...
Hi,
Everyone knows what role a transformer plays in making our circuits bulky. So what is an alternative to that. What if i want to make 12V AC from 230V AC without compromising space & weight of my overall circuit. If we come up with a solution, how much current can it handle?
Hi,
A first chance exception of type 'System.OverflowException' occured in Microsoft.VisualBasic.dll
I am trying to read registers from PLC giving different values from 0 to 65536. However, at any instant, it shows this error and the value becomes 0. Please share your knowledge and tell me why...
Thanks for your reply Klaus,
I can set the form to start maximized at all times. But the problem is while designing, How can i design the layout of form for a maximized window, I will have to know the size of a maximized for for designing the layout that way.

No, the output of TSOP1738 doesn't oscillate, It gives binary pulses as output. Afaik, Its function is to Filter & Decode an Infrared signal modulated by a carrier of 38Khz. So its input is of course oscillating, but output is simply a pulse train.
Form Resizing in visual studio 2012
Hello Everyone,
I am using Visual Studio 2012 in Visual Basic Development Settings.
When I resize my form, all the controls on that form stay to the top left corner and it is only the window that resizes. I want all the controls also to resize accordingly.
Or...
Hi,
Since 2 days I have been trying to use some library but none of them have sample codes for me to understand. And i need them because unfortunately, i am a noob in VB. Someone please help me get a suitable library to read & write data to Modbus RTU devices..
Also sample codes if possible...
Dear FvM, Thank you so so much! This information helped a lot to me. I even found some libraries which i will to use. Thank you. I Will upload my code as i finish it. And I'll come back if i get stuck somewhere in programming. Thanks for your help :)
KlausST, thanks for your interest. PLC make & model is "Delta DVP 12SE".
Schematic is what i dont need to have, as i just want to turn a Digital Output HIGH/LOW.
Code is what i am asking for.
I have attached a manual of PLC, please make sure to check chapter 4: Communications.
