8. 3 Digital outputs
The device has 2 transistor switching outputs
that are galvanically separated from the
analysis electronics using opto couplers.
The digital outputs:
• can switch DC or AC loads.
• can switch loads depending on the supply
voltage's polarity.

CAUTION!
Transmission errors and
damage to property due to
electrical faults
If the line is longer than 30 m, there is
an increased probability of transmission
errors and damage to the device due to
atmospheric discharge.
Use a shielded cable for connection to
the digital outputs.

CAUTION!
Damage to property due
to connection errors
The digital outputs are not short-circuit
proof! Connection errors can therefore
cause damage to the connections.
Ensure that the wiring is correct when
connecting the outputs.

CAUTION!
Measurement errors when
using as a pulse output
When using the digital outputs as pulse
outputs, measurement errors may arise due
to the residual ripple.
Therefore, use a mains adapter for the
supply voltage for the digital inputs and
outputs, which has a residual ripple of
less than 5% of the supply voltage.
