The DIC01DD48AV0 is a DIN-rail mount, 1-phase True RMS monitoring relay designed to monitor AC/DC over and under current and voltage. It operates on a 24 to 48 VAC/DC power supply and features two SPDT relay outputs rated for 8 A at 250 VAC. The device allows for the selection of multiple current and voltage measuring ranges via DIP-switches, with adjustable set points, hysteresis, and separately adjustable delay functions from 0.1 to 30 seconds. Programmable latching or inhibit functions and LED indicators for power, alarm, and relay status make it a versatile solution for industrial process control and equipment protection.
