DIRT24A is a smart current and voltage monitoring relay with a range of functions and flexibility that can measure current (with a range of 0.5 to 24A) and/or voltage (with a range of 0 to 250V) and output a relay switch command as an action with various adjustable parameters depending on the user’s system.

The intelligent system of the DIRT24A can be used in numerous applications such as motor and transformer overload protection, current monitoring, overvoltage trips, phase monitoring for a single-phase/three-phase system, etc.

This product is designed to be robust and reliable, with a wide temperature range and working in tough, vibration-filled environments. The real-time clock with internal NTC ensures accurate timestamps even after a power cut. It also features anti-reverse polarity protection and extreme low power consumption.

In terms of working principle, the DIRT24A provides maximum flexibility and accuracy of the measurements. It is equipped with two channels, one which can be used for measuring current (with a range of 0.5 to 24A) and another for measuring voltage (with a range of 0 to 250V).

Both the current and voltage channels allow user to set an upper and lower limit of their desired value and adjust hysteresis, rising- or falling-edge delay to determine when to trip output. User can set any desired function like “Greater than”, “less than”, “equal to”, “over voltage”, “under voltage”, “over current” or “under current”.

The DIRT24A is a dual-output device. The relay output works on different principles depending on function. But generally, it is activated when one of the prescribed parameters (voltage or current) exceed the specific value set by user. For example, it will output when voltage goes above or below a certain limit and/or when current exceeds user’s defined value.

In conclusion, the DIRT24A monitoring and protection relay is a powerful device designed for a broad range of applications. Its current and voltage measuring capabilities together with dual-output and adjustable parameters make it an excellent choice for system protection and monitoring.
