I am wiring some things to my Secu16, and setting up the inputs.
the manual says there is a type of input 4-20mA (jumper on pins 1,2).
i understand the other two electrical signal types. what is this one looking for? soemthing that will provide one of the two current levels at some indeterminate voltage?
