User manual - METER SRL-49
- 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 SRL-49 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
SRL-49
allows user to select a
conversion characteristic of several kinds: linear, square, square root, and user defined
(max.20 points length). The measured value is displayed simultaneously on 4-digit LED
display and 20-points, colour bargraph. Set relay thresholds can be displayed on bargraph
together with the measure. 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 SRL-
49 with two relays outputs can be equipped with active current output. Device SRL-49 is
equipped with RS-485 / Modbus RTU communication interface and sensor supply output. The
meter can be ordered in two power supply versions.
SRL-49
can be used for controlling and regulation of processes need proportional and
threshold control like: temperature processes (heating or cooling), valves controlling or other.
