ZHT0020 – Analog Acquisition Module

ZHT0020 is an industrial-grade standard analog acquisition product that can collect up to two analog signals (0-10V or 0-5V) on site and convert them to the 485 interface standard Modbus-RTU communication protocol for uploading. The 485 interface has a maximum communication distance of 1,000 meters and can be directly connected to on-site PLC, industrial control instruments, configuration screens or configuration software. The collection accuracy is 10-bit (1024) resolution or 12-bit (4096) resolution. It can be widely used in industrial sites, distribution cabinets and other places where analog signal collection is required.
