Intelligent wireless 4G data collector

1. Overview

The multi-channel intelligent wireless 4G data collector is a new series of ultra-low standby power data acquisition modules based on 2G/3G/4G networks from Shanghai LeZhen Detection Technology Co., Ltd. The data collection module integrates I/O and data collection in a single device, supports standard TCP protocol, and connects to the server through 2G/3G/4G network to achieve comprehensive functions such as data collection, storage, display, control, and alarm. The data acquisition module is an analog input module that can simultaneously sample 8 signals with a sampling accuracy of up to 16 bits.
Suitable for collecting various voltage and current signals, vibration signals, temperature signals, etc. from industrial sites.
