• Building automation systems connecting sensors and actuators via RS-485
• Industrial control networks requiring multi-drop serial communication
• Remote monitoring setups where reliable long-distance data exchange is necessary
• Integration into PLC and SCADA networks using RS-485 links

Key specifications

• Communication interface: RS-485 differential serial link
• Typical use: module for connecting sensors, actuators and devices in serial networks
• Topology: supports multi-drop/multi-point RS-485 networks
• Environmental suitability: intended for control panel or enclosure mounting in automation environments
• Integration: designed for compatibility with standard RS-485 masters and slaves

How to use

Install the FF LE-01MR into a suitably sized control panel or enclosure and connect the RS-485 A and B lines according to your system wiring conventions, observing proper polarity and single-ended termination where required. Power the module as specified by your control system (refer to system power provisions) and configure the communication settings on the master device to match the RS-485 parameters of connected nodes (baud rate, parity, stop bits). Verify line termination and biasing to ensure stable differential signaling over the cable run.

Usage recommendations

Use twisted-pair shielded cable for RS-485 runs and place termination resistors at the ends of the bus to minimize reflections. Keep RS-485 cable runs separate from high-voltage or noisy power lines and adhere to recommended grounding practices to reduce common-mode interference. Before deploying, test communication with intended devices and confirm addressing and protocol settings on all nodes.
