3.3.1.2. CONNECTING ANALOG INPUTS (OPTION)
The Analog In connector is used for connecting external voltage signals from other
instrumentation (such as meteorological instruments) and for logging these signals in the
analyzer‟s internal DAS. The input voltage range for each analog input is 0-10 VDC and
input impedance is nominally 20kΩ in parallel with 0.1µF.
Figure 3-7: Analog In Connector
Pin assignments for the Analog In connector are presented in Table 3-4.

3.3.1.3. CONNECTING ANALOG OUTPUTS
The rear panel Analog Output channels A1 , A2 and A3 are assigned to the NO

, NO and
NO

concentration signals of the analyzer with a default output voltage setting of 0 to 5
VDC and a reporting range of 0 to 500 ppb.
A4 is assigned a user-selected diagnostic test function (see Section 5.9.4), also with a 0
to 5 VDC default analog output voltage setting.An optional Current Loop output is
available for
A1 , A2 and A3 only.
To access these signals attach a strip chart recorder and/or data-logger to the appropriate
analog output connections on the rear panel of the analyzer. Pin-outs for the analog
output connector are:
