The SRP-73 meter is a 4-digit process meter designed for measuring of typical current or voltage signals.
Case size: (WxHxD) 72 x 36 x 97 mm
STANDARD: LED, two-coloured (red-green), 4 x 13 mm (IP 40)
OPTION: LED, red, 5 x 9 mm (IP 65)
Features of the SRP-73
- process meter in a small case
- input 0/4-20 mA, 0/1-5V, 0/2-10V, 0-60 mV, 0-75 mV, 0-100 mV, 0-150 mV
- 0, 1 or 2 relay outputs (or OC type)
- power output: 24V DC
- RS-485 / Modbus RTU
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.
Additionally, current input has overcurrent protection circuit, which protects the standard resistor.
The selection of active input is made via software, and selected input can be changed at any time.
The SRP-73 also 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. The result of which is shown on 4-digit LED display. The displayed values range can be selected by user, from -999 to 9999, plus the decimal point.
The device can be equipped with one or two relay (or OC type) outputs and is also equipped with RS-485 / Modbus RTU communication interface and sensor output.
The meter can be ordered in two power supply versions.
SRP-73 is best suited for controlling and regulation of processes needing proportional and
threshold control like: temperature processes (heating or cooling), valves controlling etc.
