RS485 differential signaling, strong common-mode interference rejection.
Each bus can host up to 32 nodes (expandable to 256) for centralized control and data distribution.
Supports Modbus RTU, Profibus, etc., directly interfacing with PLC/DCS – no gateway needed.
Built-in Flash retains and cycles the last received data during communication loss, preventing data loss.
Optional high-brightness or wide-temp panels; front panel optional IP65 for harsh environments.
Displays static background and dynamic variables (e.g., temperature, pressure) simultaneously, updating in real time without flicker.
Standard AT command set – send ASCII commands via serial port to update content, no complex development.
Smart meter concentrators, building automation, remote oil well monitoring, environmental monitoring stations, etc.
