Digital output modules with relay output provide changeover contacts at their outputs.
Settings
Digital output modules with rotary coding switch
Setting principle (page 9-81)
The delay time setting determines how long a signal of the trip unit must be present until the corresponding LED lights up and the signal is
set at the corresponding output.
Configurable digital output modules
Configurable digital output modules can be adjusted via:
- the test socket of the trip unit with the BDA
-the PROFIBUS-DP / MODBUS.
