Bender – IR207LZ – Insulation Monitoring Device

The Bender IR207LZ is an insulation monitoring device designed for unearthed AC systems (IT systems) up to 1000 V. It continuously monitors the insulation resistance between the system and earth, providing early detection of insulation faults to prevent potential hazards and equipment damage. The device features a built-in LED bar graph indicator for real-time visualization of insulation resistance levels, allowing for immediate assessment of system integrity. An adjustable response value and time delay enable customization to specific system requirements, ensuring timely and appropriate responses to insulation deterioration. The IR207LZ is equipped with an output relay that activates upon detecting insulation resistance below the set threshold, facilitating integration with alarm systems or automatic shutdown protocols. Its compact design and DIN rail mounting make it suitable for various industrial applications where reliable insulation monitoring is essential.
