HF6404
- Product Code: HF6404
Product Overview
The HF6404 remote IO controller provides remote IO control and monitoring via 4G and RS485 interfaces, suitable for industrial applications where devices are controlled and monitored through serial ports or networks. This product integrates rich hardware interfaces including 4G, RS485, 4-channel digital input, 4-channel analog input, and 4-channel digital output. It supports the Hanfeng IOTService local and remote configuration tool, and incorporates TCP/IP protocol stack, Modbus TCP, Modbus RTU, HTTP, and MQTT protocols, enabling convenient remote data acquisition and monitoring.The hardware interfaces comply with national standards, and the ESD performance supports ±15KV air discharge and ±8KV contact discharge.
Built on a highly integrated hardware and software platform, the HF6404 remote IO controller is optimized for industrial applications, smart power grids, and personal healthcare applications. Adding only one HF6404 unit can meet the needs of equipment data monitoring and transmission.
