: Paramagnetic type (built-in), or
zirconia type (external)
Measurable gas components and measuring range:
• Max. 4 components measurement including O 2 .
• 1 or 2 measuring range per component.
• Measuring range ratio
≤
1:5 (except built in O
2
)
≤

2
)
Max. 4 components and 2 ranges are
selectable including an O
2
measurement.
For measurable components and possible
combinations of measuring ranges, refer
to Tables 1 to 8.
Measured value indication:
Digital indication in 4 digits
(LCD with back light)
• Instantaneous value of each component
• Instantaneous value after O
2
correction
(only in CO, SO
2,
NO measurement
with O
2
)
• Average value after O
2
correction
(only in CO, SO
2,
NO measurement
with O 2 )
• O

average value
Analog output signals:
4 to 20 mA DC or 0 to 1 V DC, non-iso-
lated output.
Analog output corresponds to measured
value indication in 1:1.
Permissible load; 550

max. for 4 to 20
mA DC 100k
Ω
min. for
0 to 1 V DC
* Refer to Table 6, for the channel No. of
displayed values and analog output sig-
nals.
Analog input signal:
For signal input from externally installed
O
2
sensor.
Signal requirement;
(1) Signal from Yokogawa’s Zirconia O
2
sensor (Model : ZX8D*C or ZX8D*D)
(2) 0 to 1 V DC from an O
2
sensor
Input section is not isolated. This feature
is effective when an O
2
sensor is not built
in.
Relay contact output:
1a contact (250 V AC/2 A, resistive load)
Instrument error, calibration error,
range identification, auto calibration
status and maintenance status, sole-
noid valve drive for auto calibration,
pump ON/OFF.
1c contact (250 V AC/2 A, resistive load)
Upper/lower alarm contact output.
Peak count alarm contact output.
* All relay contacts are isolated mutually
and from the internal circuit.
Contact input:
Non-voltage contact (ON/0 V, OFF/5 V
DC, 5 mA flowing at ON)
Remote range changeover, auto cali-
bration remote start, remote holding,
average value resetting
Isolated from the internal circuit with a
photocoupler. Contact inputs are not iso-
lated from one another.
*Only M3.5 screw terminals are used for
all signal inputs and outputs.

Safety and EMC conforming standards:
Safety: EN61010-1
Pollution degree 2 (Note)
Installation category II (Note)
Note: Installation category, called over-
voltage category, specifies impulse
withstanding voltage. Category II is for
electrical equipment.
Pollution degree indicates the degree
of existence of solid, liquid, gas or other
inclusions which may reduce dielectric
strength. Degree 2 is the normal indoor
environment.
