Power Connection
Universal AC power source.
Gas Inlet and Outlet
One inlet (must be externally valved)
and one exhaust out. Three inlets
when option “C” is ordered.
9-Pin RS-232 Port
Serial digital concentration signal
output and control input.
50-Pin Equipment Interface Port
Analog Outputs:
0–1 VDC oxygen concentration plus
0-1 VDC range ID
Alarm Connections:
2 concentration alarms and 1
system alarm.
Remote Valve
: Used in the 3000ZA for controlling
external solenoid valves only.
Remote Span/Zero:
Digital inputs allow external
control of analyzer calibration.
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 I/O:
Serial digital communications for local
network access. For future expansion. Not currently
implemented.
Optional
Calibration Gas Ports:
Separate fittings for zero, span, and
sample gas input, internal valves
for automatic gas switching.
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 3000ZA is accurate to 2-3 %. Accordingly, internally
scheduled calibrations can vary 2-3 % per day.
