Minebea Intec PR 5230 - Digital Inputs

4.4.7 Digital inputs
The main board is equipped with 3 digital inputs for the process control. They are
electrically isolated by optocouplers, each bipolar potential-free.
The interface can be congured by software.
Depending on the order, the hardware is factory-set to "passive" (order code "DE1") or
"active" (order code "DE2").
