RS PRO Monitoring Relay 3 Phase DPDT DIN Rail Mount, Undervoltage Monitoring, 0V AC, 3A Contact Current, IP20/IP40 223-7789

RS PRO 223-7789 Monitoring Relay is a premium industrial-grade monitoring relay designed for 3 phase electrical systems with undervoltage monitoring function. It is equipped with DPDT contact configuration and is mounted on standard DIN Rails, facilitating easy integration into control panels and switchgear.

This monitoring relay operates with a supply AC voltage of 0V AC and supports a contact current rating of 3A. It employs a true RMS measurement system at 2 kHz sampling rate to ensure accurate voltage detection and protection.

Key protections include phase loss, incorrect phase sequence, phase asymmetry, undervoltage, overvoltage, neutral faults, as well as frequency deviations (over and under frequency). This enables comprehensive safeguarding of motors, machinery, and electrical installations against low voltage faults and anomalies.

The front panel features a bright green backlit LCD screen displaying fault windows, menu parameters, line or phase voltage, delay timer status, frequency in Hz, and relay status. User-friendly controls include escape, scroll, and enter keys for configuration and programming.

The relay offers adjustable on-off time delays in seconds or minutes and comes with two independent relay outputs providing dual switching capabilities. Password protection secures settings from unauthorized changes, and a fault log records the last five faults to aid monitoring and maintenance.

Constructed for robust operation within -10°C to 60°C, this device carries IP20 and IP40 ratings for protection against dust and solid foreign objects. It is proudly manufactured in India under the RS PRO series.

Equipped with DPDT contact configuration suitable for 3A contact current. Mountable on DIN Rail for easy installation in control panels. Provides undervoltage monitoring with advanced true RMS measurement at 2 kHz sampling.

Features protection against phase loss, phase sequence, asymmetry, under and over voltage. Includes selectable monitoring for overfrequency, underfrequency and neutral faults. Front panel LCD with green backlight displays key parameters and relay status.

Adjustable on-off time delay with programmable dual relay outputs. Offers password protection and logs last 5 faults for diagnostic purposes. Operates reliably within temperature range -10°C to 60°C. IP20 and IP40 rated for protection against foreign objects.

This RS PRO monitoring relay is ideal for use in industrial electrical panels, machine control, switchgear, mains distribution systems, and automation systems requiring reliable undervoltage and phase monitoring. It supports configurations for 3-phase 3-wire and 4-wire supplies, enhancing its versatility in diverse operational environments.
