Analog outputs
Analog output as switch
An example for the use of the analog output as 0/10V switch is shown in picture 7.2.5.c
1. set the gain (An.33) to 20.00
2. set X-offset (An.34) to the desired switching level

Due to the high gain the analog output switches in a relative small switching window.
Calculation of the gain
Since the analog output works always to the speciedvaluesin7.2.4thecharacteristiccanbeadjustedwith
the gain so that the total range of 0… ±10V is used.

desired value
= gain (An.33 / 43 / 49)
3.3.6 ANOUT 1 value (An.32 / 42 / 48)
Analog values for the respective input can be preset in percentage with parameters An.32/An.42/An.48.Value
8: „Digital setting“ must be adjusted as process variable. The setting is in the range of ±100 %.
