Electric inputs and outputs
Analog output per component, 0/2/4 to 20 mA,
floating, max. load 750 Ω
Relay outputs 8, with changeover contacts,
freely selectable, e.g. for range
identification, loading capacity,
24 V AC/DC /1 A, floating, non
sparking

•Pump
• AUTOCAL
• Synchronization
Serial interface RS 485
AUTOCAL function Automatic analyzer calibration
with ambient air (depending on
measured component), cycle
time adjustable from 0 (1) to
24 hours
Options Supplementary electronics with 8
additional binary inputs and relay
outputs, e.g. for external auto-
matic calibration and for PROFI-
BUS PA or PROFIBUS DP
Ambient conditions
Permissible ambient temperature
• Operation +5 to +45 °C
• Storage and transport -20 to +60 °C

storage and transport
Permissible pressure variations 700 to 1200 hPa
Sample gas
Sample gas pressure
• Without pump unpressurized
• With pump unpressurized suction mode, fac-
tory-adjusted with 2-m hose at
sample gas outlet; an upper
range value calibration is
required in case of other venting
conditions
