15.1 Analogue Outputs (Option)
The analogue output option provides a choice between a single output and three outputs. An output
is configurable for 4-20mA or 0-20mA (isolated) for connection to a chart recorder, computer or other
device for tracking the response of the analyzer. These signals are available at the connector on the
rear panel, as labelled.
The current output (0-20mA or 4-20mA) can drive a load of minimum value of 500 Ohms.
The user may set the analogue output high and low values according to their needs by modifying
OPH (output high) and OPL (output low). See section 11 for details.
For example:
By setting OPH to 2.5% and OPL to 1%, the 20mA signal indicates 2.5% and 4mA is 1%. As the
oxygen varies between 1 and 2.5%, the current signals will also vary. If connected to a computer
then these signals can be used to trigger an alarm message based on the current level (which
corresponds directly to the oxygen level).
NOTE Analogue outputs are an option which must be ordered at the time of initial purchase. If they
need to be retrofitted to an existing MK3 900 series instrument it must be returned to Systech Illinois
for processing.
