Wuhan Zhongdi Hengda -- Data Collector
(1) Product Purpose
The digital signal collector can meet the data collection requirements of various sensors with RS485 signal types. The collector integrates sampling, data management, measurement, transmission, and power supply functions into one device. It features high integration, compact appearance, convenient installation, flexible application, and high cost performance, making it suitable for working conditions where sensors are distributed dispersedly and require wireless communication, wireless networking, remote online monitoring, etc. The device adopts 4G communication, supports full-network communication standards, can simultaneously support communication with 8 client links, and supports communication protocols such as MQTT.
