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).
