3.3.1.3. Connecting Analog Outputs

The 9110T is equipped with several analog output channels accessible through a connector on the back panel of the instrument.

Output channels A1, A2 and A3 are assigned to the NOx, NO and NO2 concentration signals of the analyzer.

∙The default analog output voltage setting of these channels is 0 to 5 VDC with a reporting range of 0 to 500 ppb.

∙An optional Current Loop output is available for each.

The output labeled A4 is special. It can be set by the user to output any one a variety of diagnostic test functions (see Section 5.9.4).

∙The default analog output voltage setting of these channels is also 0 to 5 VDC.

∙See Section 5.9.4 for a list of available functions and their associated reporting range.

∙There is no optional Current Loop output available for Channel A4.

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:
