Lufft OPUS20E
for External Sensors
With up to 10 external channels/sensors
per OPUS20E.
The OPUS20E offers the highest exi-
bility and is excellent value for money.
It allowes the connection of up to 4 ex-
ternal temperature and relative humidity
sensors, as well as 2 further analogue
sensors. Intelligent BUS sensors can be
integrated via the OPUS20E’s RS485
interface (e.g. particle counter).
Air ow and differential pressure sensors
are typically connected to the OPUS20E
via analogue inputs as opposed to the
maximum of 4 external temperature or
humidity sensors that can be integrated
via a digital BUS protocol.
In connection with its LAN capabilities,
the OPUS20E is able to realize universal
measurement networks in real time.
For standard applications the Smart-
Graph 3 comes into play, and in order to
ful l the 21 CFR 11 guidelines the well-
established and proven MCPS7 software
is available.
