SWE-73-L Small Case Loop-Powered Panel Meter

The SWE73L is a cost-effective and user-friendly digital indicator designed for simplicity. This device features a single 4-20 mA current input that not only powers the device but also incorporates safety circuits to protect the internal electronics from overload. With the ability to recalculate the measured current using predefined transfer functions such as linear, square, and square root, or a fully customisable user characteristic with up to 20 points, this indicator offers flexibility in displaying accurate results. The measurement results are conveniently shown on a 4-digit red LED display, which can range from -999 to 9999, with the option to define the decimal point position. For added functionality, the SWE73L can be equipped with an optional SPDT relay. It’s important to note that while the output can drive a bulb lamp or a sound signalling device, it is not suitable for controlling purposes. Configuration of the device can be easily accomplished using an IR remote controller, with an additional LED signalling when the input current exceeds 10 mA to ensure user safety.
