Description

Product name：IR425-D4M1C-2 Bender output module

Product details:

The BENDER IR425-D4M1C-2 is a high-performance insulation monitoring device (IMD) designed for unearthed AC, AC/DC, and DC systems (IT systems). It is part of the ISOMETER® family and is specifically engineered to monitor insulation resistance in control circuits.

## Product Overview

The IR425-D4M1C-2 continuously monitors the insulation resistance of IT systems and triggers an alarm when the value falls below a specific response value. This ensures that a single insulation fault does not lead to a system shutdown, allowing for proactive maintenance.

## Technical Parameters

Below are the key specifications for the IR425-D4M1C-2:

Parameter	Specification
Nominal System Voltage ( $U_n$ )	AC 0…300 V / DC 0…300 V
Supply Voltage ( $U_s$ )	AC 100…240 V / DC 100…240 V
Nominal Frequency	DC, 30…450 Hz
Response Value ( $R_{an}$ )	1 kΩ…200 kΩ
Hysteresis	25%
Measuring Time ( $t_{an}$ )	$\leq 1 \text{ s}$ (at $C_e = 1 \mu\text{F}$ )
Max. System Leakage Capacitance ( $C_e$ )	20 $\mu\text{F}$
Output Contacts	1 Changeover contact (Alarm 1)
Connection Type	Push-wire terminals (M1C variant)

## Key Advantages

Early Fault Detection: Detects insulation degradation before it results in a fuse trip or equipment failure.
Versatility: Suitable for both AC and DC systems, including systems with power electronics (rectifiers/inverters).
AMP Plus Measurement: Utilizes a patented measurement method that adapts to system interference and leakage capacitance.
Compact Design: Designed for DIN rail mounting, saving space in control cabinets.
Maintenance Free: Does not require periodic calibration under normal operating conditions.

## Product Applications

This device is commonly used in industrial sectors where high operational reliability is required:

Control Circuits: For machinery and industrial automation.
Medical Facilities: Monitoring power in sensitive “Group 2” rooms (though specific medical variants like IR427 are also common).
Renewable Energy: Monitoring DC circuits in solar or wind power installations.
Mobile Equipment: Used in railway and crane systems where vibrations are common.

## Important Precautions (Notes)

IT Systems Only: This device is strictly for unearthed (IT) systems. Do not use it in TN or TT (earthed) systems.
Single Monitor Rule: Only one insulation monitoring device may be connected to the same electrically connected system to avoid measurement interference.
Dielectric Tests: Disconnect the ISOMETER® from the system before performing high-voltage or dielectric tests on the installation.
Wiring: Ensure the $L1/L2$ terminals and the $E/KE$ (Earth/Functional Earth) connections are secure to avoid false readings.
