3.2 Analog Outputs - I/O interface X1_ANALOG_IO
20 analog outputs are available, which are divided into five groups with 4 out-
puts each.
In the process, you can configure the following functions using a software:
• PWM signal generation
• Switch/toggle mode
• Input-dependent output mode

Group represents the five galvanically isolated groups (A...E)
**
X represents the respective channel number (0...3)
For more detailed information about the analog outputs, see the Technical Data
in the chapter "Analog Outputs (I/O interface X1_ANALOG_IO)" on page 34.
The Retry Functionality
The Retry functionality is activated when the maximum amount of the total cur-
rent per output group is exceeded. All outputs of the group are temporarily
switched off in case of an overload. The duration of the switch-off varies
depending on the frequency of the overload case.
WARNING!
Unlike a fuse, the retry functionality is not a general safety feature.
It is a software-supported convenience feature.
Always equip your connected test object with sufficient protection!
