Product Description

The IR470LY-4021 belongs to the IR470 series, which is known for its reliability in industrial environments. This device monitors the insulation resistance between the unearthed system conductors and the ground (PE). It utilizes a specific measurement principle that allows it to operate effectively in systems with high interference or electronic noise. The “-4021” variant typically signifies a specific configuration regarding response values, auxiliary voltage, or specialized factory settings tailored for specific industrial requirements.

Product Parameters

Product Advantages

• High Sensitivity: Capable of detecting minute changes in insulation resistance, allowing for maintenance before a full short circuit occurs.

• Redundant Safety: By providing an early warning (Pre-alarm), it ensures that a first ground fault does not lead to a system trip, maintaining operational continuity.

• Rugged Construction: Designed for industrial use, it can withstand electrical noise and harsh environmental conditions common in factory settings.

• Simple Interface: Equipped with LED indicators for Power, Alarm, and Fault, along with a test/reset button for easy local verification.

• Compact Design: Saves space in control cabinets while providing comprehensive protection for large electrical networks.

Important Considerations

• IT Systems Only: This device must only be installed in unearthed (IT) systems. Connection to a grounded (TN/TT) system will result in a permanent fault indication and potential damage.

• Testing Restrictions: During insulation or high-voltage tests of the plant machinery, the IR470LY-4021 must be disconnected from the system to avoid damaging the internal electronic components.

• Correct Grounding: The connection to the protective earth (PE) must be high-quality and low-resistance; otherwise, the measurement accuracy will be compromised.

• Cable Routing: Measurement leads should be kept as short as possible and separated from high-current power lines to minimize induced interference.

Product Applications

• Medical Facilities: Used in medical IT systems to ensure that power is not interrupted during critical procedures due to a single insulation fault.

• Manufacturing Plants: Protecting motor control centers and automated production lines where a sudden stop could cause significant financial loss or equipment damage.

• Elevators and Cranes: Monitoring the mobile power supply systems where vibration and movement increase the risk of cable insulation wear.

• Chemical Industry: Applied in hazardous areas where a ground fault could potentially cause a spark, leading to fire or explosion risks.
