Product Description

The N22 series Fan Failure relays monitors the current flowing through the circuit when connected in the series to Fan supply. When current signal goes out of the range, the relay status will change. The relay is provided with fixed time delay to avoid nuisance tripping. The relay has wide auxiliary power supply range from 90 to 270V AC/DC.

Advanced Fan Health Monitoring

The N22-FFR relay detects abnormal fan operation using advanced current sensing technology, providing instant feedback via clear LED indicators for both power and fan status. This early detection minimizes downtime and helps avert costly failures in HVAC and industrial automation systems.

Safe, Durable and Easy Installation

Housed in a flame retardant plastic enclosure, the relay supports mounting on a 35mm DIN rail and uses screw terminals for secure connections. Its high insulation resistance and wide operating temperature range make it suitable for demanding industrial environments, ensuring long-lasting reliability and safety.

Flexible Reset and Protection Features

Offering both automatic and manual reset options, the N22-FFR relay adapts to various operational preferences. Overload protection and rapid operate time under 100 ms ensure that any anomalies are detected and addressed swiftly, maintaining consistent fan performance and extending equipment lifespan.

FAQ's of Fan Failure Relays N22-FFR:

Q: How does the N22-FFR relay monitor fan operation?

A: The relay uses current sensing technology to accurately detect the health status of connected single-phase or three-phase fans. When a deviation in current flow is detected, the relay triggers LED indicators and output contacts for prompt notification or control action.

Q: What are the benefits of using LED indications on the N22-FFR?

A: The dedicated LEDs display both power supply status and real-time fan health, enabling quick visual verification for maintenance staff. This minimizes troubleshooting time and helps identify issues before they escalate.

Q: When should I choose manual versus automatic reset on this fan failure relay?

A: Manual reset is recommended for systems where supervised inspection is crucial after a fan failure, whereas automatic reset suits environments needing minimum interruption and immediate relay recovery post-fault clearance.

Q: Where can the N22-FFR be installed?

A: The relay is designed for 35mm DIN rail mounting, making it ideal for integration into HVAC control panels, industrial automation systems, and other enclosures, facilitating organized and reliable installations.

Q: What standards does the relay adhere to for quality and safety?

A: The N22-FFR complies with IEC 61010 and IS 13947 standards, ensuring robust safety, reliability, and performance in various electrical and industrial applications.

Q: How fast does this relay respond to a fan failure event?

A: It features a rapid response time under 100 ms, which ensures immediate detection of fan issues, allowing operators to take swift corrective action and prevent system downtime.
