The 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 (analogue/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.

Given the set of hardware features, software ability and GSM connectivity TWCT22 is an ideal product for use in wide variety of application areas. With minimal to no effort, TWCT22 can be easily integrated in an operational system with ease. Some of the application areas could be (the list is however not limited to these application areas)

Security systems
Irrigation & fire alarm systems
Building surveillance and control
Home & garden automation projects
Heating, lighting & climate control
Remote monitoring and device/equipment control

Wide coverage of GSM networks and the provision of GPRS connectivity have made it possible to interconnect systems wirelessly. TWCT22 exploits the benefits of this wireless technology and gives you control of your remote units from any part of this World. All-in-all TWCT22 is an advanced, effective and an economical solution for fulfilling your needs of remote monitoring and control applications.

Functions

Remote commands are described by three definitions:

event - an occurrence detected by the device, either a state change on one of the four digital inputs, an analogue input exceeding an alarm limit or two types of receiving messages (SMS, call)
logic - the relationship between elements
action - a state or process that is controlled by the device - a change of relay state (on, off, toggle) or sending a message (SMS, email, call).

With the use of Logics, you can constuct simple sequences, so that more than one action can be taken for an input state.

Events

Digital High to Low (you can set the de-bounce time 0-1000ms)
Digital low to high (you can set the de-bounce time 0-1000ms)
analogue input exceeds a limit
analogue input falls below a limit
user defined SMS message received
Call from recognided phone received

Logics

AND any event inputs - all events must be true
OR any event inputs - any event input must be true

Actions

Set output relay high
Set output relay low
Toggle relay output
Send user defined SMS message
Call defined phone number
Send email (only if service is provided by GSM network provider)
