Description

GSM RTU CWT***5 is an effective remote control device with high quality.  It monitors 4 dry contacts and 4 drivable relay outputs. 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 running on a real-time operating system. It gives immediate response to any change in both inputs and outputs condition. A GSM modem is embedded in the RTU, user has to subscribe a SIM card for the RTU. The RTU can be installed in any location under GSM coverage.
