Hollysys LT-Series - Field-Signal-Collect/Remote-Cloud-Transmit - Ultra-Low-Power Wide-Temp DIN-Rail Oilfield SCADA RTU
The Hollysys LT Series RTU is a rugged remote terminal unit for oil & gas, water, and utility telemetry. Key specs: ARM-based CPU, modular I/O, dual Ethernet, RS-485/RS-232, Modbus RTU/TCP, DNP3, IEC 60870-5-101/104, -40 to +70 °C, 10-36 VDC wide input.
Performs local data acquisition, logic control, event logging, and alarm dial-out at remote wells/pipelines. < 5 W standby suits solar/battery sites; built-in protocol conversion bridges legacy field devices to SCADA without middleware—cuts site visits via secure remote upgrade.
