Eltako FWG14MS radioyhdyskäytävä DIN-kiskoon, RS485-väylä, 868,3 MHz 30014072

Building automation integrators and electricians rely on the Eltako FWG14MS to bridge wireless Eltako-Funk devices with the wired RS485 bus in residential and commercial installations. Mounted on a standard DIN rail, this compact 1 TE module enables bidirectional communication between up to 128 wireless actuators and sensors when paired with an FAM14 controller, making it a cornerstone for scalable smart building systems.

Key specifications

• Wireless protocol: Eltako-Funk (EnOcean-based) at 868.3 MHz
• Wired interface: RS485 bus, powered by 12V DC (max 20 mA) via bus
• Mounting: DIN rail EN 60715 TH35, module width 1 TE (18 mm)
• Functions: Gateway, switchable repeater, bidirectional communication, telegram filtering
• Range: up to 30 m indoors, 100 m outdoors
• Operating temperature: -20°C to +50°C, protection class IP20
• Compatibility: Eltako wireless actuators/sensors and Series 14 bus components

Why choose it

The FWG14MS eliminates the need for separate wireless-to-wired converters, saving space and wiring effort. Its repeater function extends wireless coverage in challenging layouts, while telegram filtering reduces bus load for reliable performance. Configuration via Eltako PCT14 software through the FAM14 ensures seamless integration into existing projects.

Ideal use cases

• Retrofitting wireless switches and sensors into buildings with existing Eltako bus infrastructure
• Extending wireless range in large homes or offices using the repeater mode
• Centralizing control of up to 128 wireless devices in a single DIN rail cabinet
• Monitoring and controlling lighting, heating, and security devices from a central controller

Good to know

The FWG14MS is designed for indoor use (IP20) and requires an external 12V DC supply from the RS485 bus, typically provided by an FAM14. Its thermoplastic housing ensures durability, and the 18 mm width allows installation in even crowded distribution boards. For optimal performance, position the gateway centrally to the wireless devices and avoid metal obstacles.
