Pulse Input section.
Analog Output Switch
The analog output slide switch selects between 1-5V mode (left-hand position) and 4-20 mA mode
(right-hand position). In voltage mode, power is applied between the Ano+ and Ano- terminals with
the 1-5V output signal on terminal Vout (relative to Ano-). In current mode, the circuit operates as a
two-wire device that controls the current flowing from Ano+ to Ano-. In this case, Vout is not used.
