Title: I need 3-5 Volt
Post by: peterh_DK on April 12, 2007, 08:49:58 AM

Hi There,

I am using some T100MD888 units as simple  polling devices, with only 3 input and 3 outputs active and a 24 V power supply. Now I would like to connect 2-3  PIR sensors ( from www.parallax.com) - a neat little unit that requires 3.3 to 5 volt  for operation and draws < 100uA

I can se that there is a 5 volt output on the Analog connector  (which I am not using. Can I use as supply for my PIR sensor?

/Peter

if the current consumption or PIR is so low (100uA as you mentioned) then there is no problem using the analog 5V power output, which can deliver up to 10mA.

Great Thanks,  "<100uA" is what the manual states, so I'll try
