Hi guys, I'm building a temperature monitoring system.
I've got about 8 Thermistors reading into a networked IO device.
I'm feeding the Thermistors from a 5V supply (LM317) through a potential divider 47k resistor which works fine.
Q1 How many can I reasonably feed of the one supply without affecting the other results
ie
5V_____________________________________________________....... / / / \ \ \ / 47K / 47K / 47K \ \ \ | | | ------IO Input ------Input ------Input / / / \ \ \ /Thermistor /Thermistor /Thermistor \ \ \ 0V___/__________________/________________/______________......Also I need to mount this small circuit board onto DIN Rail along with the IO Module & relays etc in the cabinet.
Q2 what would you use ? I havn't found much. My best thought was to mount it onto a DIN Terminal and fix it with that. Any suggestions please.
