User manual - METER SWE-94-U
- 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.
2. GENERAL CHARACTERISTICS
The SWE-94-U meter is equipped with one current input (0-20mA), two voltage inputs
(0-10V and 0-150 mV), one RTD input (Pt 100/500/1000) and one TC input (thermocouple: K,
S, J, T, N, R, B, E). Temperature of cold ends is compensated automatically. RTD and TC
inputs are fully linearised.
It is allowed to use only one input at the same time. Input ranges are
described in the next chapter. Result is showed on 4-digit LED display.
The device is equipped with RS-485 / Modbus RTU communication interface. The meter
can be ordered in two power supply versions.
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, precision and reliability are the basic trumps of
SWE-94-U indicators.
IR remote controller is not a part of the SWE-94-U and must be ordered separately.
