User manual - METER SRP-73-XC

- 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-73-XC

meter is equipped with one voltage input 0-60 / 0-75 / 0-100 / 0-150mV.

The selection of active input is realised by software, and selected input can be changed at any
time. Additionally the

SRP-73-XC

allows user to select a conversion characteristic of several

kinds: linear, square, square root, and user defined (max.20 points length). 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 one or two relay (or OC type) outputs. Device

SRP-73-

is equipped with RS-485 / Modbus RTU communication interface and sensor supply

output. The meter can be ordered in two power supply versions.

SRP-73-XC

can be used for controlling and regulation of processes need proportional

and threshold control like: temperature processes (heating or cooling), valves controlling or

other.
