1.3 Interfaces
1.3.1 Analog Outputs
By default each X-STREAM analyzer is t-
ted with one output per channel, which can
transmit data on concentration levels to an
external data acquisition system. Up to ve
analog outputs can be installed.
The analog outputs support several operation
modes, such as 4-20 mA, 0-20 mA, as well
as the NAMUR NE 43 specications (incl.
Live Zero). Operation modes can be set in a
software menu ( 6-62).
The factory setting for analog outputs is
4-20 mA.
X-STREAM analyzers support up to five
analog outputs, which, however, do not al-
ways need to be assigned to measurement
channels which are physically present: If
a unit features less than ve channels, the
remaining analog outputs can be used to
transmit concentration levels with a different
resolution; for example, a single-channel
analyzer could be set up as follows:
Output 1: 0 … 100 % CO
2
= 4 … 20 mA
Output 2: 0 … 25 % CO
2
= 4 … 20 mA
1.3 Interfaces
All analyzer types are tted with one analog
electrical output for each channel, four status
relays, 2 Ethernet interfaces and a serial ser-
vice interface as standard.
As an option, further interfaces can be added.
Depending on the unit conguration, all in-
terfaces are accessible via either SubminD
connectors or screw terminals .
1.3.2 Status Relays
By default each analyzer provides four relays
outputs, precongured to signal the current
status of the unit according to the NAMUR
NE 44 specication ('Failure', “Maintenance
request”, 'Out of specication' and 'Function
check'). However, the operator can assign
different functions to the relays via software
menus. For a comprehensive list of available
functions, 6-68.
Note!
Any NE 44 status is also indicated by sym-
bols appearing in the display´s 1
st
line. These
symbols remain conformant to NE 44 even
when the status relays are software assigned
different functions.
Electrical details:
maximum load of 30 V / 1 A / 30 W,
can be operated as normally open (NO) or
normally closed (NC).
Further information on the status relays is
provided in the section 'Technical Data'
2-2.
