User manual - METER SUR-94
- 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 SUR-94 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 can be equipped with two or four relay (or OC type) outputs. Optionally
SUR-
94
with two relays (or OC type) outputs can be equipped with active current output, passive
isolated current output or active voltage output. Device SUR-94 is equipped with RS-485 /
Modbus RTU communication interface and sensor supply output. The meter can be ordered in
two power supply versions.
SUR-94 can be used for controlling and regulation of processes need proportional and
threshold control like: temperature processes (heating or cooling), valves controlling or other.
