IRDH575B1-435 is an insulation monitoring device from BENDER ISOMETER series, specifically designed for IT AC and DC systems. It integrates a test generator and controller, compatible with EDS46…, EDS47…, and EDS49… systems, with software version D0185 V1.80.
Features
Panel Design: Adopts a 144×96mm panel-mount design with a four-line LCD display.
Monitoring Functionality: Real-time monitoring of system insulation resistance and insulation fault localization.
Application Scenarios: Widely used in power, industrial automation, and other fields.
IRDH575B1-435 Core Functions
Insulation Monitoring: Monitors insulation resistance from 1kΩ to 10MΩ, automatically adapting to system leakage capacitance.
Measurement accuracy: ±15% within the range of 20kΩ to 1MΩ.
Fault Localization: When used with EDS systems, generates test currents of 1/2.5/10/25/50mA for selective localization of insulation faults.
Communication & Interfaces: Equipped with RS-485 interface (BMS protocol), supporting communication protocols such as Modbus RTU.
Enables networking with other Bender devices.
Self-Testing: Features automatic self-check function, allowing scheduled auto-tests every hour or 24 hours to detect internal functions and connection status.
Technical Parameters
Application Fields
Industrial Automation: Suitable for insulation monitoring of equipment such as motors, frequency converters, and control cabinets to ensure stable production line operation.
Power Systems: Used in substations and switchgear rooms to monitor the insulation status of power equipment and prevent insulation failure accidents.
New Energy Industry: Manages the insulation status of unstable power supplies in wind and solar power plants.
Rail Transit: Provides insulation protection for the traction systems and lighting systems of subways and high-speed railways.
Marine and Transportation: With the W option, it can resist vibration and impact, making it suitable for ships and railway vehicles.
