I found this article, still can't say that it is 100% true ( because it is found on the web site of ssr manufacturer I assume that there is some portion of advertisement ), but let's have a look inside :

SSO Application Notes: Solid State Relays vs. Electromechanical Relays - Solid State...
do you really need to design it? I can give you a hint where to find one or more already done - in multi output satellite lnb - they use power dividers to split the signal, you can easily cut the divider from the rest and use it in your own circuit. It is true that this approach is not very...
reading books and articles, exercising electronic circuits is a part of the process that you have to do in order to learn electronics, but academic education is the base, there are obvious things that you need to study and you need to have teacher or mentor or someone to explain them to you. I...
only in c, sorry about that, tmr0 is the same, this example run on its own rc oscillator, which is 4MHz :
I think it is not so hard to read it and to convert to asm :)
DPRG.c
IR obstacle detector for PIC12F629 and IR Remote Control Receiver RPM7138 (by Tsvetelin Velkov).
#include <system.h>...
or ask your senior design engineer / lead design engineer ;) IC design is not very common topic, I guess no one in the forum is familiar with your process specification and design rules :)
pre-loading is like - you have a 8 bit counter with period of overload of 100 ms, you need a period of 10 ms, so each time you have overload you have to write 230 in the counter - your counter will not start from 0 but from 230 and by this you will effectively shorten the overload period from...
try this one :
TMR0 value? - (using PIC16F628a Timer0).
do you have access to microchip forum? it is worth to make a registration there and to look for solutions also to ask?
some time ago when I was student I did a course in PLC and there were some practical exercises on Siemens PLCs and ladder. I think there are some good books explaining it, but the best way is to have one on your desk and to play with it ... might not be Siemens, I think most PLCs support ladder...
to kak111 - with all my respect I have to disagree with this document from tyco, some figures look strange, maybe because the document points to high power relays or just tyco points to its own production ... i don't know, but I can give controversial opinion :
Examples:
1. sensitive to...
that remind me my childhood when I was drawing my first pcb's with asphalt dissolved in benzine ... good times, unfortunately smd technology made all those attempts seldom, the same as drawing the pcb artwork in photoshop, paint, etc. - quality is not satisfactory at all. Unfortunately sometimes...
Hi,
I would like to design a similar sound sensor for finding the direction of sound. Instead of opening parallel discussion I decided to write it here, I hope no one is against that :)
I plan to use it for a robot - a mobile platform that will move around. Having the possibility to scan for...
your schematic look ok, but I want to challenge with the following question - why do you need to isolate the noise from relays? your schematics currently consists of micro controller, digital comm, relay drivers and input that is isolated with optocoupler - I don't see any noise sensitive parts...
Hello Ernest,
What is the operating frequency of your new design? Your voltage is really high, why do you want to convert from 500V DC?
The design of buck converter is explained here ...
