NDIR Gas Analyzer Specifications
Teledyne Analytical Instruments 91
Allowable load 100KΩ for 0 to 1V DC
Refer to Table2 for the channel No. of
displayed values and analog output
signals.
Analog Input Signal:
For signal input from externally installed
O
2
sensor.
Signal requirement:
(1) Signal from Zirconia O
2
sensor
(TYPE: ZFK7)
(2) 0 to 1V DC from an O
2
sensor. Input
section is not isolated. This feature is
present when an O
2
sensor is not built
in.
* Externally installed O
2
sensor must be
purchased separately.

range identification, auto calibration
status, solenoid valve drive for auto
calibration, High/Low limit alarm
contact output.
All relay contacts are isolated mutually
and from the internal circuit.
Digital Input: (option)
Voltage contact (supply 12-24VDC
(15mA Max.)) Max. 9 inputs
