Intelligent Transformer Monitoring

The Intelligent Transformer Monitoring Model ATS272 is designed as a cost effective remote control system alert device. It monitors up to 8 digital inputs and 4 solid relay outputs and 6 AD inputs and power status, onsite temperature and humidity. All of the inputs and outputs are isolation. User-defined SMS is sent to pre-configure mobile phone numbers when a pre-defined 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 AT-S272, the alarm condition brings attention to in-charge personnel immediately. Besides it allows those mobile phone users to trigger any relay output by using SMS.
