CWT5111 GPRS RTU GSM alarm and controller 8DI, 8DO, 4AI, GPRS, SMS control

CWT5111 GPRS RTU enables various devices with I/O interface and standard MODBUS protocols to communicate easily and freely over GSM/GPRS network and Internet. It can construct a smooth "GPRS Data Tunnel" between Host End and Remote End, makes an efficient communication for data transmission and remote device management. Besides, It is an ideal solution for M2M industry on factory automation, environmental monitoring and remote device management.

There is a built-in microprocessor chip that keeps running on a real-time operating system. It gives an immediate response to any change in both inputs and outputs condition. What's more, a GSM modem is embedded in the RTU, which can be installed in any location under GSM coverage. What users need to do is subscribe a SIM card for the RTU, and realize the remote control.


Function Descriptions:

1. It can be easily set up with any terminal devices.

2. It gets an emulational software.

3. It supports flexible messages, recipients and optional settings.

4. Users can set duly alarm messages.

5. There is no need to use a PC.

6. It is suitable for external application.

7. It is configurable for all input and output messages.

8. It is an industrial design with intelligent software capability, which makes it a reliable GPRS solution for data collection and transmission.

9. Multiple GPRS Transmission modes can be set, such as timer transmission, I/O trigger GPRS Transmission.

10. It can connect any serial device to GPRS and the Internet.

11. There is no need to build expensive fixed line network.

12. With the reliable GPRS network connection, it provides fast and cost-effective long-range wireless communication.
