FF FW-R1P Single Bistable Relay 85-265V AC/DC DIN Rail Mount

The FF FW-R1P is a high-quality single bistable relay engineered for precise electrical circuit control. Designed to operate across a broad voltage range of 85-265V AC/DC, this device provides flexibility for various electrical installations. It is specifically built for standard DIN rail mounting, ensuring seamless integration into modern distribution boards and control cabinets. By maintaining its state after receiving a control pulse, the relay offers an efficient solution for managing electrical loads without the need for continuous power to the coil.

Advantages

The primary advantage of the FF FW-R1P is its bistable operation, which significantly reduces energy consumption since the relay does not require constant power to hold its position. Its universal voltage compatibility allows it to be used in diverse environments, ranging from residential lighting systems to complex industrial automation setups. The robust construction ensures long-term reliability, while the DIN rail mounting standard simplifies the installation process for professional electricians and system integrators.

Suitable for

• Lighting control systems in residential and commercial buildings
• Industrial automation and process control
• Building management systems
• Remote switching of electrical circuits

This relay may not be suitable for applications requiring high-frequency switching or rapid cycling, as bistable relays are designed for state-retention rather than high-speed pulse modulation. It is also not intended for use in circuits exceeding its rated current capacity or in environments with extreme moisture or dust without appropriate protective enclosures.

Key specifications

• Voltage range: 85-265V AC/DC
• Mounting type: DIN rail (TH-35)
• Operation mode: Bistable (impulse)
• Function: Single channel switching

To use the FF FW-R1P, mount the device onto a standard 35mm DIN rail within a suitable electrical enclosure. Connect the control signal wires to the designated input terminals and the load circuit to the output contacts. Once installed, a momentary control pulse will toggle the relay state, which will remain latched until the next pulse is received. Ensure all connections are tightened according to the manufacturer's torque specifications to prevent loose contacts.

What to consider before purchase

• Verify that the control voltage matches the relay input requirements
• Ensure the load current does not exceed the relay contact rating
• Confirm available space on the DIN rail within your distribution board
• Check if the application requires a bistable or monostable switching logic

For optimal performance and safety, always ensure that the power supply is disconnected before performing any wiring. It is recommended to use appropriate wire ferrules for all connections and to verify the circuit functionality with a multimeter after installation.
