Products Name: BENDER IR425-D4M1C-2 Insulation monitoring device
PRODUCT DESCRIPTION
BENDER IR425-D4M1C-2 Overview
The BENDER IR425-D4M1C-2 is an insulation monitoring device (Isometer®) for monitoring the insulation resistance of unearthed (IT) AC and DC systems. It is designed for the early detection of insulation faults, thereby increasing the safety, reliability, and availability of electrical systems.
Product Detailed Description
Function:
Continuous monitoring of the insulation resistance in unearthed (IT) systems.
Issues an alarm signal when the insulation resistance falls below a preset alarm threshold.
Suitable for AC, DC, and mixed AC/DC IT systems.
Employs the AMP measuring principle to ensure reliable measurement even in the presence of high system leakage capacitances.
Features two separate, adjustable alarm thresholds.
Integrated self-test function for regular checking of the device's functionality.
Offers various interfaces and communication options for easy integration into monitoring systems.
Features:
Suitable for AC, DC, and mixed IT systems.
AMP measuring principle.
Two separate alarm thresholds.
Adjustable response delay.
Self-test function.
Selectable fault location current.
RS-485 interface, supports Modbus RTU.
Configurable output relays.
Multilingual menu.
Parameter setting and status indication via display.
