Builtin RS485 termination: 120 Ω resistor on the output terminal with a toggle to enable/disable termination, helping to reduce signal reflections on the bus. Stable power and current: includes a selfrecovery fuse and protection diode to maintain steady voltage and current during overcurrent events, improving reliability in harsh environments. Easy to use for all levels: simple, intuitive design that accommodates beginners and experienced users alike without requiring specialized setup. Clear status monitoring: external LED indicators for power and data transmission, allowing quick verification of operation and link status. Reliable RS485 compatibility: designed for standard RS485 networks, enabling straightforward integration with controllers, sensors, and existing communication modules. Practical use scenarios: Industrial automation: connect sensors and actuators to a PLC or SCADA system over RS485 for reliable data collection. Building automation: link multiple RS485 devices (meters, controllers, displays) to a central controller or data logger. Prototyping and development: interface microcontrollers or development boards with RS485 networks for testing and demos.
