Bistable Single Radio Relay FF FW-R1P-P with Multifunctional Mounting, Power 85–265V AC/DC

FF FW-R1P-P is a bistable single radio relay with multifunctional mounting and a wide supply range of 85–265V AC/DC. The device provides a latching switching function that retains its contact state after power loss, making it suitable for remote control of lighting, small motors and other electrical loads. Designed for integration in radio-based switching systems and for retrofit installations, the relay offers a compact footprint and straightforward electrical connections for fast installation.

Advantages

The relay’s bistable (latching) mechanism ensures the last commanded state is preserved when power is removed and restored, reducing the need for additional memory or configuration. Its wide supply voltage range (85–265V AC/DC) allows compatibility with various mains environments. Multifunctional mounting options simplify installation in different enclosures or distribution boards, while radio control capability supports wireless integration into existing automation setups.

Suitable for

• Remote control of lighting circuits in homes and commercial premises
• Switching small motors and actuators that do not require high inrush protection
• Retrofit projects where state retention after power loss is needed
• Radio-controlled switching systems and distributed automation networks

Key specifications

• Operating mode: bistable (latching) single-pole changeover
• Supply voltage: 85–265V AC/DC
• Control: radio/remote actuation compatible with wireless switching systems
• Mounting: multifunctional mounting options for panel or DIN-style installation
• Load type: resistive and inductive loads such as lamps and small motors (observe load limits)
• State retention: mechanical/electrical latch preserves contact position after power interruption

How to use

Connect the device according to the wiring diagram supplied with the product, ensuring correct supply polarity for DC installations and proper isolation before wiring. Mount the relay using the appropriate mounting method for your enclosure or panel and terminate load and control conductors to the designated terminals. Pair the relay with compatible radio transmitters or controllers following the pairing procedure in the user manual. Verify proper operation by actuating the radio control and confirming that the relay changes and retains state as expected.

Usage recommendations

For reliable operation, install the relay in a dry, ventilated location within the specified ambient temperature range and ensure wiring complies with local electrical codes. Confirm that the connected load does not exceed the relay’s rated current and take into account inrush currents for inductive loads. Use compatible radio controllers and perform initial testing before finalizing the installation to ensure correct pairing and state retention behavior.
