ISOLATION CONTROLLING SENTINEL

Product catalog summary

Specifications:
The document outlines the technical specifications for a permanent insulation monitoring device. It operates on a power supply of 115-230-400Vac at 50/60Hz, with a maximum mains voltage of 500Vac and a consumption of 2VA. The intervention time is 500ms, with a threshold range of 50kOhm to 300kOhm and a threshold accuracy class of 15% ffl. The device includes a potentiometer for intervention sensitivity adjustment and a relay output with an AC1 contact rating of 12A at 250Vac and 8A at 24Vdc. Terminals are designed for 10mmq connections, and the device has an internal resistance of 1MOhm.

Protection and Material:
The front panel has a protection degree of IP40, while the terminal side is rated at IP20. The case is made of self-extinguishing material compliant with UL94 – V0 standards.

Environmental Conditions:
The device operates within a temperature range of -10 to +40 °C and can be stored between -40 to +80 °C. It can handle a maximum relative humidity of 85%.

Mounting and Dimensions:
The device is mounted on a DIN 35mm EN6075 rail, with dimensions conforming to 2 mod. DIN 43880. It is colored RAL 7035 and weighs 190g.

Features:
The device features solid-state electronics, is insensitive to vibrations, and includes a trimmer for threshold adjustment. It has a green LED for operation indication and a red LED for fault indication. A test button is available to check functions, and a reset button is provided for system reset. The device also includes a sealable transparent door and connections with 6mmq terminals.

Connection Diagrams:
The document provides connection diagrams for different systems: Star (Y) system with neutral (4-Wire), Delta (D) system without neutral, and single-phase systems. An example of alarm connection is also included.

Reference Standards:
The device complies with IEC/EN61869-1 standards.
