Digital inputs
There are 1-32 digital inputs available for control purposes.
The polarity – normal open (NO) / normal closed (NC – and a
delay can be configured according the application. The signals
are available for the output matrix, block matrix, user‘s
programmable logic etc.
The contacts connected to digital inputs DI1 … DI6 must be dry
(potential free). These inputs use the common internal 48 Vdc
wetting voltage from terminal X3:1, only.
NOTE! These digital inputs must not be connected parallel with inputs of an
another device.
Label and description texts can be edited with VAMPSET
according the application. Labels are the short parameter
names used on the local panel and descriptions are the longer
