Inputs And Outputs; Trigger Function - HBM PAD4001A Operating Manual

PAD4001A/4003A

Inputs and outputs

The two I/Os can be used either as inputs or outputs.
You can also set different switching levels (TTL or PLC)
for the inputs. On delivery, both I/Os are set as inputs
with a TTL level. Specify the function of the I/Os as in­
puts with commands IM1 and IM2, and the function as
outputs with OM1 and OM2.
Notice
The electronics must be operated with a supply voltage
of between 12 and 30 V. Incorrect connections between
the supply and interface cables or digital inputs/outputs
can cause irreversible damage.
Check the correct assignment of the connections before
switching on for the first time.

Trigger function

In Trigger mode (command IMD1), the electronics have
four different trigger functions:
S Pre-triggering by level
S Pre-triggering by external (digital) signal
S Post-triggering by level
S Post-triggering by external (digital) signal
Gross or net values can be used as input values. The
filter settling time can be optimized by the actual elec­
tronics (command AST).
