Model 3000PA
Teledyne Analytical Instruments
•
Analog Outputs
0-1 V dc concentration output, plus
0-1 V dc range ID.
•
Alarm Connections 2 concentration alarms and 1 system
alarm.
•
Remote Valve
Used in the 3000PA for controlling
external solenoid valves only.
•
Remote Span/Zero
Digital inputs allow external control
of analyzer calibration. (See Note,
below.)
•
Calibration Contact To notify external equipment that
instrument is being calibrated and
readings are not monitoring sample.
•
Range ID Contacts Four separate, dedicated, range relay
contacts. Low, Medium, High, Cal.
•
Network
For future expansion. Not
implemented at this printing.
Optional:
•
Calibration Gas Ports
Separate fittings for zero, span and
sample gas input, and internal valves
for automatically switching the gases.
• Current Signal Output Additional isolated 4-20 mA dc plus
4-20 mA dc range ID.
Note: If you require highly accurate Auto-Cal timing, use external
Auto-Cal control where possible. The internal clock in the
Model 3000PA is accurate to 2-3 %. Accordingly, internally
scheduled calibrations can vary 2-3 % per day.
