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 four
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 specications (incl.
Live Zero). Operation modes can be set in a
software menu ( 6-63).
The factory setting for analog outputs is
4-20 mA.
X-STREAM analyzers support up to four
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 four 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 conguration, 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, precongured to signal the current
status of the unit according to the NAMUR
NE 44 specication ('Failure', “Maintenance
request”, 'Out of specication' 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 pro-
vided in the chapter 'Technical Data'
2-2.
