It is great but there are a few questions about it I hope you can answer them: - What is the meaning of RYIN and RXIN? - You say that it is a three wire circuit but I can only seen two points of connection for the PT100. Is it because the signal conditioner of the three wire PT100 isn´t drawing? - The OUTPUT connector is where I can find the 4-20 mA? I hope...<br/> <br/> This post is a snippet, to see the full content visit this blog or http://www.dapj.net/.

How can we use them for Long Battery Life Mail from AD If LED flashes at 5-10 K Hz at even 50% Duty Cycle. It may save some power and improve life. So it is just an idea, it may not solve the problem. The idea was to improve battery life and give uniform light for annunciators. It may not be good for flashlights.
