Intended use
The Type6126 Electropneumatic Converter is used to convert a direct current input signal in-
to a pneumatic output signal for measuring and control tasks. The electropneumatic converter
is particularly suitable as an intermediate element between electric measuring devices and
pneumatic controllers or between electric control devices and pneumatic control valves.
The input of the electropneumatic converter is a load-dependent direct current from 0 or 4
to 20mA or a DC voltage signal from 0 or 2 to 10V with a 24V DC supply. The output is,
for example a pneumatic signal of 0.2 to 1bar (3 to 15psi) or 0.4 to 2 bar (6 to 30psi) or
special ranges up to 5bar (75psi).
The device is designed to operate under exactly dened conditions (e.g. input signal, pres-
sure). Therefore, operators must ensure that the device is only used in operating conditions
that meet the specications used for sizing the device at the ordering stage. In case operators
intend to use the device in other applications or conditions than specied, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The device is not suitable for use outside the limits dened by the technical data. Further-
more, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described in these instructions
Qualicationsofoperatingpersonnel
The device must be mounted, started up, serviced and repaired by fully trained and qualied
personnel only; the accepted industry codes and practices must be observed. According to
these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their
specialized training, their knowledge and experience as well as their knowledge of the
applicable standards.
