User manual for regulated current source SZP-73
- Do not use the unit in areas with significant temperature variations, exposed to
condensation or icing.
- Do not use the unit in areas exposed to direct sunlight.
- Make sure that the ambient temperature (e.g. inside the control box) does not
exceed the recommended values. In such cases forced cooling of the unit must
be considered (e.g. by using a ventilator).
The unit is designed for operation in an industrial environment and must
not be used in a household environment or similar.

GENERAL CHARACTERISTICS
Regulated current source
SZP-73
allows generation of user settable current (in range
4-20 mA). Increasing and decreasing of output current can be made using local keyboard.
Device displays present value of output current recalculated according to set display range
(-999 do 9999 with free selectable decimal point). Quick view and regulation of output current
is possible at any time. The device can replace all two wire analogue current sources
(4-20mA) used for controlling of industrial processes.
