Port 1 - analog measured-value outputs / digital inputs
One analog measured-value output is available at the plug connector, port 1. The maximum burden totals 550Ω.
Furthermore, up to four digital inputs are available at port 1, depending on the analyzer version and its features.
This instrument comes with active 4-20 mA current outputs without galvanic isolation with a common reference potential, so that
galvanic isolation against the analyzer is not absolutely necessary.
Via the digital inputs at port 1, the higher-level system controller can control up to four measuring points individually and trigger
analyses.
The layout of the port 1 plug connector and detailed signal specifications are shown in the terminal diagrams in the appendix.
Optional ready-to-connect control cables (refer to appendix) measuring 10 and 20m in length, or D-sub plug connectors with screw-
type terminals are available for simple and easy installation.

Port 2 - digital outputs
The following digital outputs are available on the port 2 plug connector:
Status outputs (3): Measurement active, ready mode, stand-by and setup mode
Limit-value alarms (6): Violation of upper limit for all gas types as well as violation of lower limit for CH
Measuring-point switch (3)
Test gas valve (1): Control of an externally installed test gas valves
The "open collector" transistor outputs are short-circuit resistant and can be read and/or used to control the solenoid valves either by
using the 12-V supply voltage of the analyzer or by an external voltage supply of 35VDC max.
The layout of the port 2 plug connector and detailed signal specifications are shown in the terminal diagrams in the appendix
separately for the different analyzer versions. Optional ready-to-connect control cables (refer to appendix) measuring 10 and 20m in
length, or D-sub plug connectors with screw-type terminals are available for simple and easy installation.
Connector module at the analyzer:
RS 232 interface
The RS 232 interface is used for the digital output of measured values with time stamp on a PC or an external data logger. An IBM-
compatible PC with serial R232 interface and a suitable terminal program are required for transmission. The terminal is a standard
feature included in Microsoft operating systems, Windows 95 and higher.
Note that without additional amplifiers transmission via an RS232 interface only works perfectly with cable lengths of up to a
maximum length of 20 meters.
Connector module at the analyzer:
PROFIBUS interface (option)
A suitable interface is available on the underside of the analyzer for the output of measuring data, limit-value alarms and status
messages and for controlling the analyzer via a Profibus system. The test certificate contains a note stating whether this interface is
activated / enabled. A detailed description of the interface, including installation information, is available in the appendix to this
documentation.
