3.3.3 Analog Outputs
There are eight DC output signal connectors on the ANALOG
OUTPUTS connector block. There are two connectors per output with
the polarity noted. See Figure 3-5.
Figure 3-5: Analog Output Connections
The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing oxygen,
from 0 V at 0 ppm to 1 V at full scale ppm.
(Full scale = 100% of programmable range.)
0–1 V dc Range ID: 0.25 V = Low Range
0.5 V = Medium Range
0.75 V = High Range
1 V = Air Cal Range
4–20 mA dc % Range: Current increases linearly with increasing
oxygen, from 4 mA at 0 ppm to 20 mA at full
scale ppm. (Full scale = 100% of programmable
range.)
4–20 mA dc Range ID: 8 mA = Low Range
12 mA = Medium Range
16 mA = High Range
20 mA = Air Cal Range
