Typical application wiring
.
Outputs 4-20 galvanically isolated
Outputs 4-20mA galvanically non-isolated
Outputs 0-10V
Range of supply voltages and resistor values
Uss . . . . . 9 to 30Vdc
Uss1 . . . . 9 to 30Vdc
Uss2 . . . . 9 to 30Vdc
R1max[Ω] = 50 * Uss1[V] - 450
R2max[Ω] = 50 * Uss2[V] - 450
Rmax[Ω] = 50 * Uss[V] - 450
Rzmin . . 20 kΩ
LCD Info mode
The output range settings can be verified without a use of the computer by
pressing the button on the left side of the device (button is placed behind
small hole - see picture). For button pressing use thin instrument, for example
paper clip.
Upper line of the LCD display shows value of CO2
concentration corresponding to output current 4mA
(output voltage 0V).
Press the button again and upper line of the LCD
display shows value of CO2 concentration
corresponding to output current 20mA (output
voltage 10V).
