Output Options
All HMP60 series probes and HMP110 series probes, with the exception
of the HMP110REF reference probe, can be ordered with analog output
channels. Probes that use analog output can also use the RS-485 interface
for temporary service access (Vaisala Industrial Protocol serial line
commands) and Modbus RTU communication.
For installations where permanent digital output is required, the HMP110
model can be ordered as a digital-only probe (select either Modbus, RS-
485 or Interface for Vaisala devices (VDIGI) as the output when
ordering).
NOTE
When HMP110 is ordered as a digital probe, analog output channels are
not available.
The following table lists the output options available in HMP60 and
HMP110 probes.
