INTRODUCTION
1.1 General Description
The Series 9510 Carbon Dioxide (CO
2
) Analyzer is a microprocessor based instrument providing accurate
and repeatable trace or percent carbon dioxide measurements. The sensor used in the Series 9510 is a
non-dispersive infrared type, which does not react chemically with the sample gas. Due to its robust
design, a comparatively low frequency of re-calibration is required.
The standard analyzer is housed in a NEMA 1 enclosure rated for general purpose use. The front panel
contains five switches that provide access to the analyzer's settings. Carbon d ioxide values are displayed
on a 10.2 mm (0.4") high 4-1/2 digit liquid crystal display (LCD). The instrument is equipped with three
CO
2
alarm relays and one instrument status alarm relay. All four relays are Form C (SPDT) types rated at
10 amps at 115/230 VAC / 30 VDC. The relays are user configurable for fail-safe operation. In addition to
the four alarm relays, the Series 9510 Carbon Dioxide Analyzer has a built-in audible alarm and three red
LEDs for audible and visual indication of a CO
2
alarm condition. The audible alarm may be manually
canceled at any time. If the audible alarm is canceled and the alarm event continues, indications of this
condition will still be available through the front panel LEDs and relay contact(s).
The Series 9510 Carbon Dioxide Analyzer comes equipped with two standard analog outputs, 4-20 mADC
and 0-2 VDC, which are scalable by the user. For communications capability, the Series 9510 Carbon
Dioxide Analyzer can be equipped with optional RS-232C serial communications. RS-485 is also
available as an option. The analyzer can be powered from either 115/230 VAC @ 50-60Hz or 18-32 VDC
input, with battery operation an option for the AC powered versions (not available in explosion proof
configurations).
The Series 9510 Carbon Dioxide Analyzer offers users a choice o f PPM or PERCENT measurement
ranges.Consult the factory for the appropriate range designations prior to ordering.

Optional Equipment Descriptions
*
The Series 9510 Carbon Dioxide Analyzer incorporates standard features that make it immediately
suitable for many applications. However, for certain requirements, the user may desire to augment the
capabilities of the instrument by equipping it with one or more of the available options, as described below.
Please note that some of these options are not available with the open diffuser sensor configur ation
1.2.1
Optional Open Diffuser Configuration
The Series 9510 Carbon Dioxide Analyzer comes in two sample gas configurations, depending upon
customer requirements. It is normally configured for process applications as a flow through system with
sample input and sample output fittings. It can also be supplied with an optional open diffuser
configuration for measurement of carbon dioxide in the air and/or gas surrounding the instrument.
