Oxygen Analyzer
Dual Channel
Relays:
- 4 relays total (2 SPDT form
C and 2 Normally Open)
- All Contacts 250VAC 6 Amps
resistive load.
- Form C relays will act as
set points with user programmable hysteresis. One relay will
be assigned to each channel.
- The normally open relays shall
be programmable for jet wash operation. This
programming will be selectable as independent, or acting in
concert to allow the use of a single
compressor for both channels on.

- D.O. channels shall indicate
D.O. over a programmable range.
- TSS channels shall indicate
TSS over a programmable range.
- 4
and 20 mA electrical values adjustable through key pad over
2 mA range
