1 Introduction
Model 3000PA
Teledyne Analytical Instruments
•
Alarm Connections
2 concentration alarms and 1 system
alarm.
•
RS-232 Port
Serial digital concentration signal output
and control input.
•
Remote Probe
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.
