Product Overview

HIT-RTU series products are the wireless remote control terminal developed by Shenzhen HiThings Technology Co., Ltd. The internal adopts the STM32 series high-performance ARM controller chip from the industry-leading STMicroelectronics company and combines the industrial wireless communication module from Quectel company, RTU has the characteristics of strong stability, high reliability, real-time, and wide application. It is a new generation of remote monitoring and control terminal combine the telemetry, telecontrol, telecommunication, remote-adjust function with RS232,RS485 communication function. HIT-RTU wireless remote control terminal series products are the high-performance monitoring and control device which integrates analog signal acquisition, digital signal acquisition, relay control output and wireless data communication function. Can be directly connected to the standard sensors output analog signals ,various level signals, dry contacts, pulse signals, etc. Can be used as the master station of industrial Modbus-RTU protocol to connect the various instrumentation of Modbus-RTU protocol(customized).It's the best way for the small-scale process signal to implement wireless monitoring and control.
