3.4.2 Analog Outputs
There are three DC output signal connectors with screw terminals
on the panel. There are two wires per output with the polarity noted. See
Figure 3-3. The outputs are:
0–10V % Range:
Voltage rises with increasing oxygen
concentration, from 0V at 0 percent oxygen to
10V at full scale percent oxygen. (Full scale =
100% of programmed range.)
0–10V Range ID: 03.33V = Low Range, 06.66V = High Range,
10V = Air Cal Range.
4–20 mA % Range: Current increases with increasing oxygen
concentration, from 4 mA at 0 percent oxygen to
20 mA at full scale percent oxygen. (Full scale =
100% of programmed range.)
3.4.3 Alarm Relays
The three alarm-circuit connectors are screw terminals for making
connections to internal alarm relay contacts. There is one set of contacts
for each type of alarm. Contacts are Form C, with normally open and
normally closed contact connections capable of switching up to 1.0
ampere at 125 VAC into a resistive load (2A for 30 VDC).
