Q26 GSM RTU is designed as a cost effective remote control system alertdevice. It monitors up to 8 dry contacts and 8 drivable relay outputs and 4 AD input.User-defined SMS is sent to pre-configure mobile phone numbers when a pre-definedalarm condition happens. These pre-configured mobile phone numbers can belong totechnicians or engineers who are responsible in handling corresponding alarms. With theaid of this GSM RTU, the alarm condition brings attention to in-charge personnelimmediately. Besides it allows those mobile phone users to trigger any relay output byusing SMS. The output can be connected with alarm indication device, such as alarm, andothers.There is a built-in microprocessor chip running on a real-time operating system. Itgives immediate response to any change in both inputs and outputs condition. A GSMmodem is embedded in the GSM RTU, user has to subscribe a SIM card for the GSMRTU. The GSM RTU can be installed in any location under GSM coverage.
