Brief Introduction

Wireless Data Acquisition Module WT-06 is an industrial class, high-performance, low-power, long-range micro-power radio frequency wireless transmission module. It provides 4 digital inputs, and 4 analog inputs. It converts the wired signal to wireless data transmission. It is special design for distributed multi-point monitoring applications, to solve the industrial field wiring problems of difficult, high cost.


WT-06 Wireless Data Acquisition Module using half-duplex module, provides wireless transmission to instead of cable. Built-in industrial-grade module RF chip based on spread spectrum frequency hopping technology, in the stability, anti-jamming capability and receiver sensitivity are beyond the existing GFSK module. Built-in high-performance low-power high-speed microprocessors, data processing capabilities, computing speed, data integrity are higher than the market similar products.

WT-06 Wireless Data Acquisition Module built-in single-chip processing procedures, customers do not need to configure it, put on the onsite can be applied, simple, easy to use, for remote monitoring and control of the onsite to provide a simple and convenient solution.


Integrated the Wireless GSM 3G RTU S280, it can create a front-end I/O monitoring, wireless data transceiver, Wireless GSM 3G RTU S280 for data processing, send SMS Alert users and forwarding to SCADA, OPC Server, cloud platform and other monitoring center system.
