6.2.11 Output signals
A voltage of 0...±11,5 VDC represents the selected size in the range of 0...±115 %
with a resolution of ±10 Bit at the output. 100% correspond to the bracket values
specified in Fig. 6.2.10. In order to be able to balance load-dependent voltage drops,
the limitation at the output of the characteristic amplifiers is ±115 %.

Process variables, that change only slowly, as for example the power module
temperature, can be output over two virtual analog outputs (ANOUT3 and 4). This is
realised through generation of a PWM-signal (pulse-width-modulation) on a digital output.
At that the period T is adjustable from 1...240 s.
