NDIR Gas Analyzer

Specifications

 

 

 

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

O2 sensor.

Signal requirement:

(1)Signal from Zirconia O2 sensor (TYPE: ZFK7)

(2)0 to 1V DC from an O2 sensor. Input section is not isolated. This feature is present when an O2 sensor is not built in.

*Externally installed O2 sensor must be purchased separately.

Digital Output: (option)

1C contact (24V DC/1A, resistive load) max.15 outputs

Instrument error, calibration error, 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

Remote range change over, auto calibration remote start, remote hold, average value reset, Isolated from the internal circuit with photocoupler.
