3.8 Digital outputs

The digital output can be used to indicate the status of the "safe pulse block". It should be noted that this status
indication is not fail-safe.

load

For evaluation in a control system.

With SK 225/235E and use of the
AS-i (yellow cable), DO1 must not
be subjected to load, as the load
may be too high for the AS-i.

In the inverter is supplied by a 24V
module on terminals 44 (+24V) and
40 (GND), SK CU4-24V-123-B or
SK CU4-24V-140-B, the digital
output may only have a load of
maximum 150 mA.

P434 [-01]

If "switch-off of the 24V supply" is selected as the safe shut-down method, the digital output may not be able to
be meaningfully used, as it is switched off with the 24 V supply. It must be ensured that no external voltage is
introduced via the digital output.
