BFT B EBA RS485 Link-master & slave module P111468 27082

The BFT B EBA RS485 Link-master & slave module is an electronic communication module designed to provide RS485-based master/slave connectivity between compatible BFT automation devices. It enables synchronized control and reliable data exchange over a two-wire RS485 bus, simplifying integration of multiple controllers and peripherals in gate and access automation systems. The module supports structured communication topology and reduces the need for complex point-to-point wiring, helping to maintain system coherence and facilitate coordinated operation of actuators and sensors.

Advantages

This RS485 Link-master & slave module offers stable serial communication with reduced wiring complexity and straightforward integration into existing BFT automation setups. The device enables synchronized commands and status sharing between linked units, improving coordinated movements and system diagnostics. Its compact electronic design allows installation within control panels or housing provided by BFT devices, and its RS485 interface is suitable for reliable long-distance communication in electrically noisy environments.

Suitable for

• Gate and barrier automation systems requiring multiple coordinated controllers
• Access control installations where devices must exchange status and commands
• Automation environments needing RS485 bus integration for longer cable runs
• Retrofit projects that consolidate separate controllers into a linked network

Key specifications

• Interface: RS485 serial communication (two-wire differential bus)
• Functionality: Link-master and slave modes for synchronized control
• Application: Designed for use with compatible BFT gate and access automation equipment
• Installation: Electronic module for mounting inside control enclosures or compatible housings
• Communication: Supports multi-node bus topology for coordinated operation

How to use

Install the module within the control enclosure of the BFT system according to the manufacturer's mechanical and electrical guidance. Connect the RS485 A/B bus wires to the corresponding terminals, ensuring correct polarity and proper termination where required. Configure the linked devices to master or slave roles through the BFT control settings and verify addressing and communication parameters such as baud rate and parity to match the network. After wiring and configuration, perform functional tests to confirm synchronized responses and status exchange between linked units.

Usage recommendations

Use shielded twisted-pair cable for the RS485 bus and apply termination resistors at the ends of the line when the bus spans longer distances. Keep RS485 wiring separate from high-voltage power cables to minimize interference. When integrating multiple devices, document node assignments and communication settings to simplify maintenance and troubleshooting.
