Our company is a professional manufacturer of remote controller, industry GSM alarm system, GSM RTU and so on. We can provide many kinds of GSM products for our customers with high quality and competitive price.
We hope to get a lot of chances to build up long time business relationship with all kinds of buyers.

CWT5011 GSM RTU is an effective remote control device with high quality. User-defined SMS can be sent to pre-configure mobile phone numbers when a preset alarm condition happens. These pre-configured mobile phone numbers can belong to technicians or engineers who are responsible in handling corresponding alarms. With the aid of this RTU, the alarm condition brings attention to the person on duty immediately.
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.
