Analog output signals:
4 to 20mA DC or 0 to 1V DC,
isolated internally from circuit and ground;
12 outputs max.
max. load 550Ω for 4 to 20 mA DC
min. 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
