SZP-73 Regulated Current Source in a Small Case

Meet the SZP-73 Regulated Current Source, your solution for precise current generation in the 4-20 mA range. This device simplifies output current adjustments via an intuitive keyboard, displaying the current value on a customisable range from -999 to 9999 with an adjustable decimal point. Ideal for industrial process control, it effectively replaces two-wire analogue current sources and offers easy access to current regulation. Equipped with a 24V DC / 100 mA output, it powers measuring transducers, and its RS-485 port facilitates seamless data transmission in monitoring systems. Easily configurable using a local keyboard or the S-Config software over RS-485, the SZP-73 is a dependable and feature-packed addition to any industrial setup.

Product Highlights

The SZP73 is a regulated current source that provides users with the ability to generate a customisable current within the range of 4-20 mA. This versatile device allows for easy adjustment of the output current through its local keyboard, enabling both increasing and decreasing values. The SZP73 conveniently displays the current output value, which is recalculated based on the set display range of -999 to 9999, allowing for a selectable decimal point. With its quick view and regulation capabilities, users can efficiently monitor and control the output current as needed. This device is a suitable replacement for all two-wire analogue current sources (4-20 mA) typically employed in industrial process control. Additionally, the SZP73 features a 24V DC / 100 mA output designed for supplying measuring transducers and an RS-485 port that facilitates data transmission in production process monitoring systems. Configuration of the meter can be done locally using the keyboard or through the RS-485 communication port using the free S-Config software.
