Hey everyone, how bout we start a thread to help out new people and old, anything from straight and simple to generic.
I saw someone post this already but
on a 4 to 20ma device you can use a 250 ohm resistor to make the device 0 to 5 VDC or 500 ohm for 0 to 10 VDC
Honeywell Modutrol Motors-Have a bunch of them that are potentiometer and you need a DC input instead? Honeywell makes a module that you can plug into the motor to change it to VDC, you can find the PDF on the module here
Also Honeywell has the famous "Gray Book" you can find it here, its a big download
