4-20 mA (qty. 1 to 8 O2 probes)

4-20 mA (qty, 1 to 8 pass through each probe, qty. 4 programmable averages)

12 bit

Less than 500 ohms

"IN CAL" (qty. 2 to 8 from individual probes)

"LOSS OF PLC"

"AVERAGE WARN" if one or more probes drop out of an average. "AVERAGE FAILED" for each average when only one probe in the average remains valid.

Each probe utilizes its own autonomous conditioning electronics, including its own power supply. Any failure in the OxyBalance system will not affect the individual 4-20 mA signals going to the control room for each probe.

4 programmable averages from 2-8 probes

1.) Probe fails (4-20 mA to default condition of 3.5 mA or 21 mA

2.) Probe is in cal (SPS / IMPS contact, must share with control room)

4-20 mA signals to be wired in series to the PLC and to the DCS I/O marshalling panel such that the loss of the PLC will not affect the transmission of the individual probe signals to the DCS. If PLC power, I/O cards or processor card(s) are lost, 4-20 mA signals from the probes are still transmitted to the control room.

Password protection configuration changes in programmable averages.
