Dold Monitoring Relay Undervoltage Monitoring DPDT DIN Rail 24 to 60 V dc, 220-415 V ac IL5881.12/100 DC12-280V 5-200kOHM

Dold IL5881.12/100 DC12-280V 5-200kOHM monitoring relay is an insulation monitor designed for DC networks. It features undervoltage monitoring with a double pole double throw (DPDT) contact configuration and is easily mountable on DIN rails. The product supports a wide range of supply voltages including 24 to 60 V dc and multiple AC voltages from 220 V up to 415 V, providing versatility for various industrial applications.

The relay allows adjustable alarm values for earth fault resistance between 5 and 200 kΩ, enabling precise fault detection with programmable memory and hysteresis settings to ensure stability during operations. It includes convenient delete and test buttons; both can be operated externally or connected for remote control, increasing operational flexibility.

Compact and robust, the device measures 90 mm in height, 61 mm in length, and 35 mm in width, making it suitable for installations where space is limited, such as control panels in electrical and automation industries.

Designed to comply with rigorous international standards like IEC 255, EN 61557, and VDE 0413, it ensures high reliability and safety in electrical systems. The relay is IP20 and IP40 rated, protecting against solid objects and water splashes, suitable for industrial environments.

Typical use cases include electrical network safety monitoring in industrial plants, automation systems, and other commercial or manufacturing settings requiring insulation resistance management. The relay effectively monitors insulation resistance to prevent potential faults and hazards in DC circuits.

Operates on 24 to 60 V dc with AC supply range 220 to 415 V ac. DPDT contacts provide reliable switching capability with 4 A contact current. Adjustable earth fault alarm threshold from 5 to 200 kΩ. DIN rail mounting simplifies installation in electrical panels.

Compliant with IEC/EN and UL standards for safety and performance. Compact design with dimensions 90 x 61 x 35 mm (HxLxW). IP20 and IP40 rated for protection in industrial settings.
