Electrical characteristics 
Analog outputs 1 analog current output per component, 0/2/4/NAMUR ... 20 mA, 󹪞oating,
max. load 750 Ω
Relay outputs 8, with changeover contacts, freely selectable, e.g. for fault, loading ca‐
pacity 24V AC/DC/1A, 󹪞oating, non-sparking
Binary inputs 3, dimensioned for 24 V, 󹪞oating
• Pump
• AUTOCAL
• Synchronization
Serial interface ELAN (RS485), PROFIBUS-PA/DP as option
AUTOCAL function Automatic calibration (adjustment) of all channels with ambient air (in case
oxygen is present as measured component) or nitrogen (depending on
measured component),
adjustable cycle time from 1 … 24 hours. If 0 hours is entered, the cycle is
deactivated.
AUTOCAL cycle must be activated for certi󹪝ed emission measurements
Options Add-on electronics, with 8 additional digital inputs and 8additional relay
outputs, for e.g. triggering of automatic calibration, PROFIBUS PA/DP

Gas inlet conditions
Sample gas pressure
• Without pump

before device: On the inlet side, the overpressure of the gas with respect to
ambient pressure must not exceed 45hPa.
after device: On the outlet side, the gas outlet must be depressurized
against ambient pressure.
• With pump
before device: Depressurized suction mode
after device: On the outlet side, the gas outlet must be depressurized
against ambient pressure.
