User manual - CONTROLLER PUR-49D
- 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 PUR-49D device has a universal input that can be configured to work as: a current
input (in the range 0 - 20mA), as a voltage input (in the range 0-10V and 0-150 mV), as an
RTD input (operating with Pt 100/500/1000 sensors) and as a TC input (operating K, S, J, T,
N, R, B and E type thermocouples). The device automatically compensates the temperature of
cold junction of thermocouple sensor. RTD and TC inputs feature full linearization of
characteristics. Only one input type can be used at a time. The exact measurement ranges of
the inputs are quoted in the next chapter. The measurement is shown on a 4-digit LED display.
The device can be equipped with 1, 2 or 4 relay outputs and one OC-type output (not
available in the 4 relay output version), which can be controlled from the measuring inputs via
Modbus protocol or a PID controller implemented in the device with two control loops and an
auto-tuning option. Optionally, the device (in version with two relays and OC-type output) can
be equipped with: an active current output, a passive isolated current output or an active
voltage output. An RS-485 communication interface and a sensor transducer power supply
output are available as standard. The device is available in two power supply versions.
Exact description of functions is provided in further section of the instruction.
The
PUR-49D is designed to regulate such processes as heating / cooling temperatures
with adjustable delay times for the operation of the output relays and controlling of valve
levels.
