TWCT22 is an advanced yet simplified Remote Terminal Unit. Taking advantage of the reliable, widespread GSM networks and the supported GPRS service, TWCT22 becomes a remotely accessible unit from any part of the world. Using an embedded feature rich web server interface, you can configure various parameters of TWCT22. The inputs present on TWCT22 can be used for monitoring of external devices or connecting sensors (analog/digital). Alarm conditions can be configured for monitoring of these inputs. Since TWCT22 supports SMS and SMTP protocols, the device can be configured to send SMS/Email whenever alarm conditions occur. TWCT22 also gives you the freedom to control the states of the connected outputs.
By sending a simple SMS you can change/get the status of the outputs.
