Product Description

The N96-Digital Frequency relay monitors the Frequency of the circuit continuously . The N96DFR shall have 2 set points , one for Under Frequency (UF) & other for over Frequency (OF). When Frequency goes out of the range selected , the respective relay status will change .The relay checks for its healthiness first & then starts monitoring voltage signal. The relays are provided with common settable trip time delays .Digital FR has a facility for user to program AUTO/MANUAL RESET and NORMAL/FAIL SAFE TRIPPING of relays. Also it has connectivity of RS232/485 as an additional option. User can program the relay for Under , or Over Frequency or both combined protections.

Precision Frequency Monitoring and Protection

The N96D-FR Frequency Relay offers dependable frequency monitoring within a 40-60 Hz range. Designed with advanced electronic circuitry, it provides over and under frequency protection for sensitive electrical systems, safeguarding equipment from abnormal frequency conditions.

User-Friendly Operation and Indication

With its digital LCD display, adjustable set points, and LED status indication, the N96D-FR simplifies system configuration and monitoring. Front-panel buttons and selectable automatic/manual reset enhance convenience, ensuring rapid adaptation to varying operational requirements.

Durable Construction for Demanding Environments

Constructed from high-grade ABS flame-retardant plastic, the relay endures harsh conditions with up to 95% humidity (non-condensing) and a broad temperature range. The reliable SPDT silver alloy contact ensures long mechanical life and performance stability. Panel mounting and screw terminals facilitate secure and easy installation.

FAQ's of Frequency Relays N96D-FR:

Q: How does the N96D-FR Frequency Relay enhance electrical system safety?

A: It continuously monitors the system frequency within a 40-60 Hz range, providing immediate over and under frequency protection. This prevents damage and potential malfunctions of connected equipment, ensuring overall system stability and safety.

Q: What process should be followed for mounting and wiring the relay?

A: The N96D-FR is designed for panel mounting. Simply fix the unit to the front panel (96 x 96 mm cutout) and use the rear screw terminals for secure electrical connections. Ensure all wiring is completed with supply voltage within 90-270V AC/DC.

Q: Where can the N96D-FR be used effectively?

A: It is ideal for industrial installations, utility substations, and commercial panels where monitoring and protection of power frequency is critical. Its robust design and wide environmental tolerances make it suitable for demanding indoor environments.

Q: When should the automatic or manual reset mode be selected?

A: Automatic reset restores operation as soon as the frequency returns to the set range, suitable for non-critical shutdowns. Manual reset is preferable in safety-sensitive contexts, requiring operator verification before reconnection after a frequency event.

Q: What are the key benefits of the adjustable set points and operate time?

A: Adjustable lower and higher set points allow precise frequency protection tuning, while the configurable operate time (0.1-10 sec) minimizes nuisance tripping and caters to specific application needs.

Q: How is relay status and fault indication provided on this device?

A: The N96D-FR uses a bright LED indicator to display relay status and quickly alert users to frequency faults or abnormal events, enhancing operational visibility and response.
