SST O2I-Flex Manual

O2I-Flex Oxygen Interface
FEATURES
 Provides the electronics necessary to power
and control SST's range of dynamic oxygen
sensors
 High accuracy linear output

Selectable output measurement ranges:
Standard ranges of 0-25% O
0-100% O or fully adjustable via RS232 when
2
configured in 0-100% O
 Multiple outputs:
4-20mA, 0-10
V
DC
interface
 Externally triggered automatic or manual
calibration. Calibration can also be initiated via
an on-board push button switch
 Can be calibrated in normal air (20.7% O
any other known O
 Cycling 3.3 logic output allows direct
V
DC
monitoring of the O
diagnostic purposes
 Selectable output filtering allows adaptive, fast
and dynamic or slow and stable output
response
 Power and Sensor Operating LEDs
 Removable polarised screw terminals for easy
wiring
