Description
The Simex SRP-77 is a Process Meter with two rows of display. The first one presents measuring value and the second one programmed values: max. and min.
The meter is equipped with one current input 0-20 / 4-20mA and one voltage input 0-5 / 1-5 / 0-10 / 2-10V. Additionally current input has overcurrent protection circuit, which protects standard resistor.
Software allows the user to select active input, and this can be changed at any time.
The SRP-77 also allows the 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. The result of which is shown on 4-digit LED display.
The displayed values range can be selected by the user, from -999 to 9999, plus decimal point.
The device can be equipped with one or two relay (or OC type) outputs making it possible to control processes.
Device SRP-77 is equipped with RS-485 / Modbus RTU communication interface and sensor supply output.
Ideal applications of the SRP-77 could be for controlling and regulating processes needing proportional and threshold control like: temperature processes (heating or cooling), valves controlling etc.
