6-2 Control Functions
865-UM001A-EN-P – July 2009
Digital Inputs There are 6 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 another device.
Label and description texts can be edited with SetPointPS according
the application. Labels are the short parameter names used on the
local panel and descriptions are the longer names used by
SetPointPS.
