The SRP-73 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-73 allows user to select a
conversion characteristic of several kinds: linear, square, square root, user defined (max.20
points length) 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 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 can be used for controlling and regulation of processes need proportional and
threshold control like: temperature processes (heating or cooling), valves controlling or other.
