CWT5011 SMS alert Gateway is designed as a cost effective remote control system alert device. 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-defined alarm condition happens.

The output can be connected with alarm indication device, such as alarm, and others.
