User manual - METER SWE-73-L
2.
GENERAL CHARACTERISTICS
The
SWE-73-L
is a simple digital panel indicator, equipped with one measurement input
(current input, 4-20mA) used simultaneously as device power supply input. Current input has
additionally overcurrent protection circuit, which protects standard resistor.
The
SWE-73-L
allows user to select a conversion characteristic of several kinds: linear,
square, square root, and user defined (max.20 points length). Result is showed on 4-digit LED
display. Displayed values range can be selected by user, from -999 to 9999, plus decimal
point.
Optionally
SWE-73-L
can be equipped with bistable relay output. The device can be
configured via IR remote controller. Easy assembling, small dimensions, precision and
reliability are the basic trumps of
SWE-73-L
indicators.
IR remote controller is not a part of the
SWE-73-L
and must be ordered separately.
