of the following data:
O2 concentration,
Oxygen Concentration, alarm settings/status, Fault status
Analog Outputs:
Voltage, 0-1 VDC or 0-5VDC or 0-10VDC +/- 0.5% @ 1K input min.
Non-isolated 4-20 mA: +/- 0.5% , negative ground (loop is powered by analyzer)
maximum loop impedance 500
. Range ID Voltage output
Alarm Outputs, optional
Relay dry contacts rated 5Amp @ 250 VAC, 5 AMP @ 30 VDC
Alarm 1 & Alarm 2: Field adjustable Form C,
Configurable for Fail Safe or Fail Alarm mode, Ascending or Descending trip.
Fault alarm: 1 Form B . Status LEDs for each alarm.
Response Time:
< 15 seconds for 90% response due to step change in ppm oxygen @ 1 SCFH flow;
approximately 5 minutes to less than 10 ppm from cold start after exposure to air
Accuracy:
+ 2 PPM at 0-50 PPM Oxygen
+ 3 PPM at 51- 500 PPM Oxygen
