User manual - METER SRP-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.

GENERAL CHARACTERISTICS

The

SRP-94

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-94

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-

with two relays (or OC type) outputs can be equipped with active current output, passive

isolated current output or active voltage output. Device

SRP-94

is equipped with RS-485 /

Modbus RTU communication interface and sensor supply output. The meter can be ordered in

two power supply versions.

SRP-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.
