There are six analog outputs. Each output can be set either for voltage or current. Each analog
output from the digital/analog converter is a voltage. This is split into two outputs, one of which
is converted into a current output and the other kept as voltage. This is illustrated in
where for example X4:1 is the voltage output and X4:2 is the current output.
The allowed load current of the voltage output is max. 5 mA.
The allowed load resistance of the current output is max. 550 ohms.
Figure 2-12 shows AO1 connected for voltage output and AO2 for current output.
