Measurable component and measurement range:
Measured values can also be displayed
from externally mounted O
2
analyzer. In
case of Zirconia O
2
sensor, measurable
range is shown above.
Max. 5 components including O
2
sensor
can be measured and 2 measuring ranges
are available. For measurable compo-
nents and possible combinations of
measuring range, refer to Tables 1 to 5.
Principle of measurement: No, SO

Measured value indication:
Digital indication in 4 digits
(LCD with back light)

connected. Instantaneous value converted
into O

are added with measurement of NO, SO
2
and CO only. Display is selectable.
Analog output signals:
4 to 20mA DC or 0 to 1V DC, non-isolated
output ; 12 points max.
Analog output corresponds to measured
value indication in 1:1.
Permissible load resistance;
550
Ω
max. for 4 to 20 mA
DC100k

min. for 0 to 1V DC
Analog input signal:
For signal input from externally mounted zir-
conia O
2
sensor (when ZFK7 is used)
For signal input from externally mounted O
2
analyzer.
0 to 1 VDC from an O
2
analyzer.
Input section is not non-isolated. This fea-
ture is effective when an O
2
sensor is not
built in.
Input signal triggers measured concentra-
tion indication and O
2
correction.
Contact output:
1a contact (250V AC/2A, resistive load)
Instrument error, calibration error, range
discrimination, auto calibration status and
maintenance status, pump ON/OFF, peak
alarm.
1c contact (250V AC/2A, resistive load)
Upper/lower alarm contact output.
(for each channel)
Power disconnection alarm.
* All relay contacts are isolated mutually
and from the internal circuit.
Contact input: No-voltage contact (ON/0V, OFF/5V DC,
5mA flowing at ON).
Remote range changeover, auto calibration
remote start, remote holding, average value
resetting, pump ON/OFF.
Isolated from the internal circuit with
photocoupler. Contact inputs are not iso-
lated from one another.
Transmission output:
Solenoid valve drive signal for automatic
calibration; open collector output (50 mA or
less), used in combination with sampling
module.
Rated operating conditions:
Power supply; 85 to 264 V AC, 50/60Hz (3-
pin inlet terminal used)
Power consumption; 60VA
Ambient temperature; -5˚C to 45˚C
Ambient humidity; 90% RH max.
Storage conditions:
Ambient temperature; -5˚C to 45˚C
Ambient humidity; 100% RH max., non-con-
densing
