User manual - METER SRP-147
- In order to minimize fire or electric shock hazard, the unit must be protected
against atmospheric precipitation and excessive humidity.
- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,
humidity, corrosive gasses and oils.
- 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 SRP-147 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
SRP-147 allows user to select a
conversion characteristic of several kinds: linear, square, square root, user defined (max.20
points length) and 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.
The device can be equipped with two or four relay (or OC type) outputs. Optionally SRP-
147 with two relays (or OC type) outputs can be equipped with active current output, passive
isolated current output or active voltage output. Device SRP-147 is equipped with RS-485 /
Modbus RTU communication interface and sensor supply output. The meter can be ordered in
two power supply versions.
SRP-147
can be used for controlling and regulation of processes need proportional and
threshold control like: temperature processes (heating or cooling), valves controlling or other.
