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.) 

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).
