Analog Outputs

7.7.2
The I/O and Relay Option has 1 analog output that can be configured with the software to voltage output or current output. The table
shows the specification for the analog output.
The analog output is protected in overvoltage conditions.

Digital Inputs

7.7.3
The I/O and Relay Option has 6 digital inputs. By default, the digital inputs are not isolated, because there is an external wire between the
connector pins 19 (D ) and 23 (GND). The digital inputs can be functionally isolated from the PCB ground of the I/O and Relay Option
GND
by removing the wire. The digital inputs are polarity free.
Digital inputs are overvoltage protected.
