BENDER IR425-D4M1C-2 Insulation Monitoring Device

Description

BENDER IR425-D4M1C-2 Insulation Monitoring Device

Product Dimensions：

The BENDER IR425-D4M1C-2 is a sophisticated insulation monitoring device designed for unearthed AC, AC/DC, and DC systems (IT systems). It is part of the ISOMETER® family, specifically engineered to ensure high electrical safety by detecting insulation faults at an early stage.

Here is a detailed breakdown of the product in English:

1. Product Description

The BENDER IR425-D4M1C-2 is a compact insulation monitoring device (IMD) used to monitor the insulation resistance $R_F$ of IT systems. It utilizes the patented AMP Plus measurement principle, which allows it to function accurately even in systems with high leakage capacitances or modern power electronics (such as frequency converters).

Key Features:

• Universal Application: Suitable for AC, DC, or hybrid AC/DC systems.

• Two Response Values: Provides two separately adjustable response values (Alarm 1 and Alarm 2).

• Digital Display: Features an integrated LC display to show the current insulation resistance and parameter settings.

• Compact Design: Designed for DIN rail mounting (standard 2-module width).

2. Technical Parameters

The technical specifications ensure reliability in industrial and medical environments.

3. Product Advantages

• High Sensitivity: Detects even minor insulation degradations before a full-blown short circuit occurs.

• Automatic Adaptation: The device automatically adjusts to the system leakage capacitance, ensuring stable measurements.

• Advanced Diagnostics: Includes self-monitoring and a connection test for the earth conductor and system cables.

• User-Friendly Interface: Easy commissioning via the front buttons and clear LCD feedback.

• Future-Proof: Handles modern DC loads and distorted waveforms common in digitalized industries.

4. Safety & Precautions (Notes)

• De-energized Installation: Ensure the system is powered down before wiring the device to prevent electric shock.

• Earth Connection: A reliable connection to the functional earth (PE) is critical for measurement accuracy.

• IT System Only: This device is strictly for IT systems (unearthed). Do not use it in TN or TT (grounded) systems.

• Parameter Locking: Once configured, ensure the settings are protected to prevent unauthorized changes during operation.

5. Applications

The IR425-D4M1C-2 is widely used in sectors where power continuity is mission-critical:

• Industrial Control Systems: Monitoring PLC circuits and motor control centers.

• Mechanical Engineering: Protecting complex machinery from unexpected shutdowns.

• Renewable Energy: Monitoring DC side insulation in small solar installations.

• Mobile Power Units: Emergency generators and mobile clinics where a reliable ground is not always available.

• Medical Facilities: Used in group 0 or group 1 medical locations to monitor specialized equipment.
