1.2.2.5 USS Customer Interface
(SK CU1-USS, Option)
In addition to data connections, the USS customer units are also
equipped with conventional digital inputs and outputs.
Via the existing relay contacts, a mechanical motor brake can be
controlled or readiness for operation can be communicated to a
higher level system.
The digital input has a 2.5V switching threshold for the evaluation
of the temperature sensor. The input can, however, also be used
for an emergency stop function.
