Product Description
IMD-IM20-H
The VIGILOHM IMD-IM20-H is an advanced device from Schneider Electric designed to monitor ungrounded/IT electrical networks, specifically tailored for medical environments. It belongs to the Vigilohm range and adheres to IEC standards, which mandate the use of Insulation Monitoring Devices (IMD) in IT medical premises. This device plays a critical role in ensuring the safety and reliability of medical electrical systems by continuously monitoring insulation resistance and promptly alerting in case of ground faults or transformer issues.
Key Features and Functions:
1. Insulation Resistance Measurement
The IM20-H measures the system’s insulation resistance by injecting a low-frequency AC current between the network and ground.
It is designed for AC, DC, and ACDC medical IT systems, capable of monitoring networks up to 230VAC and 230VDC.
2. User Configuration:
Settings are configured according to medical standards via the HMI (Human-Machine Interface) screen on the front of the device.
Insulation alarm thresholds can be set from 50 kilohms to 500 kilohms.
The device also includes settings for transformer overheat and overload alarms.
3. Display and Monitoring:
The black and white screen displays insulation resistance readings ranging from 100 ohms to 10 megohms.
An automatic self-test is conducted every 5 hours, with the option for manual testing on demand.
4. Alarm System:
If the insulation resistance falls below the preset threshold, indicating a ground fault, the device triggers an alarm through the IMD output relay within 4 seconds.
Once the fault is resolved, the alarm is automatically cleared, and the relay returns to its normal state.
The device also monitors and provides alarms for transformer overheat and overload conditions.
5. Power Supply:
The IM20-H can be powered by a source ranging from 110VAC to 230VAC or from 125VDC to 250VDC, with a tolerance of plus or minus 15%.
6. Installation:
The device supports both DIN rail and flush mounting installations.
It features ingress protection ratings of IP52 for the front face and IP20 for the rear.
The device is rated for overvoltage category III, ensuring robust performance in medical environments.
7. Communication:
Equipped with an RS485 communication port, the IM20-H uses the Modbus protocol for integration into network systems.
The VIGILOHM IMD-IM20-H is a critical component for maintaining the safety and functionality of medical IT networks. It provides reliable insulation monitoring, quick fault detection, and transformer condition alerts, ensuring the integrity and safety of medical electrical systems.
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.
