User manual for - INDICATOR SWE-73-T
- Do not use the unit in areas where there is risk of explosions.
- Do not use the unit in areas with significant temperature variations, exposure to
condensation or ice.
- 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
is a simple digital panel indicator, equipped with Pt 100/Pt 500/Pt 1000
type input, with automatic connection recognition (two, three or four wire sensor). The
measurement range spans from -100 °C to +600 °C, and input is fully linearised accordingly to
PN-A2:1999 standard. Result is showed on 4-digit LED display. Device
is equipped with RS-485 / Modbus RTU communication interface.
The parameters (offset, baud rate) can be selected while ordering. The device can be
configured via IR remote controller or optionally by PC via RS-485 interface, or using simple
RS-232 to IR converter. Over more communication interface RS-485 enables data
transmission in any monitoring system equipped witch Modbus RTU protocol.
Easy assembling, small dimensions, precision and reliability are the basic trumps of
indicators.
IR remote controller is not a part of the
and must be ordered separately.
