Product Description
IMD-IM400
Key Features and Functionality:
1. Purpose:
Monitors the insulation resistance of ungrounded (IT) electrical networks.
Measures system insulation by injecting a low-frequency AC current between the network and ground.
2. Compatibility:
Suitable for large and disturbed AC, DC, and ACDC systems.
Can monitor networks up to 830V AC when connected to neutral, 480V AC when connected to line, and 480V DC, with capacitance up to 500 microfarads.
3. Measurement Capabilities:
Insulation resistance: From 10 ohms to 10 megohms.
Capacitance and temporary faults can also be displayed.
4. Configuration and Settings:
Settings can be configured on the front of the device via the HMI screen or through the communication port.
Configurable parameters include network type, alarm and pre-alarm thresholds, alarm delay (from 0 to 7200 seconds), and more.
5. Display and Alarms:
The black and white screen shows insulation resistance, capacitance, and temporary faults.
Auto-test initiates every 5 hours automatically, or on demand.
An alarm is triggered through the IMD output relay if insulation resistance drops below the set threshold, indicating a ground fault.
The alarm clears automatically once the fault is resolved, and the alarm relay returns to normal.
6. Power Supply:
Can be supplied by a 110VAC to 440VAC source or a 110VDC to 440VDC source, with a tolerance of ±15%.
7. Installation and Protection:
Designed for flush mounting, such as on an enclosure door.
Front face ingress protection: IP5.
Rear ingress protection: IP20.
Overvoltage category III with a rating of 300V.
8. Communication:
Equipped with an RS485 communication port supporting the Modbus protocol.
Summary
The IMD-IM400 is recommended for monitoring large and disturbed electrical systems in industrial environments, where maintaining electrical integrity is critical. By continuously monitoring insulation resistance and providing timely alarms for ground faults, it ensures the safety and reliability of electrical networks, helping to prevent potential hazards and system failures.
Frequently Asked Questions
How does power monitoring work?
✅Power monitoring systems typically comprise a power metering device to gauge overall facility power consumption and assess power quality. Coupled with a monitoring system, these tools track energy distribution within the facility post-metering.
What is power monitoring unit?
✅A Power Monitoring Device plays a crucial role in measuring power consumption, facilitating energy-saving endeavors. While electricity itself remains invisible, it represents a convenient and ubiquitous form of energy that transforms into various manifestations such as heat, light, sound, and power, all of which are extensively utilized.
What is vigilohm?
✅Enhance safety and boost process availability with Vigilohm's range of insulation monitoring devices (IMDs). Designed for IT (ungrounded) networks, these devices offer a straightforward, dependable solution for insulation monitoring, communication, and fault location. Discover how this streamlined offering can elevate both personnel and equipment safety while optimizing process availability.
How does insulation monitor work?
✅Insulation Monitors by DOLD: Insulation Monitoring Made Simple
DOLD's insulation monitors provide seamless insulation monitoring solutions. In the event of an insulation fault, the measuring circuit triggers, allowing a proportional small current to flow. The device's electronics evaluate this current, issuing a notification if the insulation resistance drops below a predefined threshold (response value).
What is an isolation monitor?
✅Explore the Importance of Isolation Monitoring in High-Voltage Vehicle Systems
Isolation monitoring stands as a pivotal safety feature in high-voltage vehicle systems. In modern vehicles, the high-voltage system remains completely isolated from the vehicle chassis. This design safeguards against electrical shock by preventing a single fault in the high-voltage system from posing a risk to individuals.
