Introduction: ZHC4921 is an industrial-grade 4G RTU that provides 4 channels of DI, 4 channels of DO, 4 channels of AI and 1 channel of RS485 interfaces. It supports local logic processing operations, automatic collection and active reporting, Modbus RTU/TCP adaptation, and automatic calibration thresholds. Special functions such as reporting, configuration software docking, and wet and dry node IO detection support one-to-one and many-to-one networks. The configuration software interface window is visualized, allowing users to connect, debug, and configure equipment on-site or remotely.
