User manual - METER PDU-4x0-W
- 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
meter is equipped with one current input 0-20 / 4-20mA and one voltage
input 0-5 / 1-5 / 0-10 / 2-10V. Current input has additionally overcurrent protection circuit,
which protects standard resistor. The selection of active input is realised by software, and
selected input can be changed at any time. Additionally the
allows user to select a
conversion characteristic of several kinds: linear, square, square root, user defined (max.20
points length) and volume characteristics of a cylindrical tank in the vertical and horizontal
position. Result is showed on 4-digit LED display. Displayed values range can be selected by
user, from -999 to 9999, plus decimal point.
Depending on version the device can be equipped with: two relay outputs, two OC type
outputs, one relay and one passive isolated current output or one OC type and one passive
isolated current output. Device
is equipped with RS-485 / Modbus RTU
communication interface and sensor supply output. The meter can be ordered in two power
supply versions.
The device has 4 buttons being used for main presets programming. To get high
protection level, the keyboard is mounted under transparent cover. To allow user to change
presets without opening the cover, an IR sensor is mounted. Remote controller keyboard is
equivalent to the device keyboard (Note, that remote controller is not a part of the
set – it is an additional equipment).
can be used for controlling and regulation of processes need proportional
and threshold control like: temperature processes (heating or cooling), valves controlling or
other.
