    Isolated analogue signal

    So you just want to control the supply voltage of the heater from the PLC? You could look at a current buffer circuit which allows increased current to be drawn by the heater but without loading the PLC output. How much current does the heater draw? Is the potentiometer controlling this current...

    Leading and Lagging AC Power

    I thought that an ideal inductor and core required no magnetising current, so there would be no need for PFC. I thought phase was important because this is the part that allows the load to use this magnetising current when the field collapses. When it's out of phase, say 90 degrees this current...

    Leading and Lagging AC Power

    Hi Ollie Yes your correct. When you have a current in an inductor it stores energy in the magnetic field created around it. When the power is removed this energy has to go somewhere. If it was an ideal inductor it would just stay there. But all real inductors have resistance so this energy is...

    Hi Trevor That was nice. I didn't know your name sorry. I think thats why it is so much better to sign off a thread with your name. They could be a robot as far as I am concerned. Its much more friendly when people do that. Lets all get to know each other, it will make for a much better forum...

    Relay driver

    Here is my initial thoughts. However, depending on the relay you choose, your 2 ms pulses may be too fast to switch on the relay. P1 adjust your initial on time of the relay and the HEF40106 is powered from 12 Volts. You may have to tweak a few components to get it to work how you want. But it's...

    wireless transmission

    Hello Although it would be much more fun to build your own, it's not that easy because you have to ensure you are not radiating too much power and you are not out of band. You can buy very cheap transmitters and recievers on the net but make sure you choose one that you can use in your country...
