RT424F24 24VDC DPDT 2-Coil Latching PCB Relay 8A 5kV Isolation

The RT424F24 is a high-quality bistable PCB power relay designed for applications requiring reliable switching, low power consumption, and memory retention without continuous coil energization. Featuring a DPDT (Double Pole Double Throw) contact configuration and a 24VDC two-coil latching mechanism, this relay is ideal for industrial automation, energy management systems, building controls, instrumentation, telecommunications equipment, and power control applications.

Utilizing a bistable 2-coil magnetic system, the RT424F24 changes state using separate set and reset coils and maintains its last switching position even when power is removed. This latching design significantly reduces power consumption and heat generation, making it an excellent choice for energy-efficient systems and battery-powered equipment.

The relay provides a DPDT (2 Form C) contact arrangement, enabling simultaneous switching of two independent circuits. With a contact rating of 8A at 250VAC and a maximum switching capability of up to 10A, it is suitable for controlling motors, lighting systems, HVAC equipment, power supplies, and other electrical loads requiring dependable switching performance.

Operating from a 24VDC coil supply, the relay features a low coil power consumption of approximately 650mW. Its efficient magnetic system ensures reliable switching while minimizing energy usage during operation. The coil resistance of approximately 886 supports stable and predictable coil performance.

One of the standout features of the RT424F24 is its reinforced 5kV isolation between coil and contacts. This high level of electrical isolation enhances safety, protects sensitive control electronics, and reduces the risk of electrical interference in critical applications.

Designed for PCB mounting, the relay integrates easily into control boards and electronic assemblies. Its durable construction and high-quality internal components provide long operational life and dependable switching performance, even in demanding industrial environments.

The RT424F24 is suitable for applications where relay position retention, energy efficiency, and reliable load switching are essential, making it a preferred solution for modern automation and control systems.
