6-channel analog acquisition module

Introduction: ZHC4661 is an industrial-grade 4G DTU that provides 4-channel AI, 2-channel AO and 1-channel RS485 interfaces. It supports Modbus RTU/TCP adaptation, automatic collection and active reporting, 4~20mA analog control collection, and automatic calibration threshold reporting. Other special functions include one-to-one and many-to-one networks, and visualization of the configuration software interface window, allowing users to connect, debug, and configure equipment on-site or remotely.Can be widely used in power systems

Introduction: ZHC1661 is an industrial-grade RJ45 RTU that provides 4-channel AI, 2-channel AO and 1-channel RS485 interfaces, supports 4-channel Socket, Modbus RTU/TCP adaptive, 4-20mA analog automatic reporting, 12-bit sampling accuracy, AO remotely follows AI, configures cloud to monitor PLC in real time, automatically obtains IP address, DNS domain name resolution and other special functions

Introduction: ZHC0661 is a low-frequency half-duplex LoRa data transmission terminal that supports point-to-point communication protocol. It has 4 channels of AI detection and 2 channels of AO output. It has local logic and inter-device logic settings, AI range conversion, and supports AES communication encryption. Using the serial port for sending and receiving lowers the threshold for wireless applications and enables data transmission from the serial port to LoRa.
