Analog output signals:
* Inputs/outputs of analog signals are possible by combining with the input/ output terminal module.
4 to 20 mA DC or 0 to 1 V DC, non-isolated output ; 12 points max.
max. load 550 Ω for 4 to 20 mA DC
min. load 100 kΩ for 0 to 1 V DC
* Refer to Table 9.2, 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 (when 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.
(Depend on O
2
input signal, measured concentration indication and
O
2
conversion.)
