DIB01CD485A is a precision True RMS AC/DC over or under current monitoring relay designed for DIN-rail mounting in accordance with DIN/EN/EC 60715. The device features a 0.1 to 5 A AC/DC measuring range with current measurement through an internal shunt, adjustable current level on a relative scale (10 to 110% of full scale), and programmable hysteresis (0 to 30% on set value). It provides an 8 A SPDT relay output (selectable as normally de-energized or normally energized), adjustable delay function from 0.1 to 30 seconds, and programmable latching or inhibit function at the set level. The relay operates with a 24 to 48 VAC/DC power supply (±15%), features galvanically separated power supply with 2 kV to 4 kV dielectric voltage isolation, and includes LED indication for power supply, alarm, and output relay status. This monitoring relay is ideal for industrial applications requiring precise current monitoring, load protection, and fault detection in control systems and machinery.
