Monitoring/Control Unit can be programmed via text messaging.
April 15, 2009 -
LinkTx G3 enables text messages from GSM devices to turn equipment on or off, change system parameters, and request measurement/alarm information. Emergency conditions, temperature, voltage, current, and digital readings can be sent to up to 16 GSM mobile telephone numbers and 4 number groups. Compatible with GSM networks worldwide, unit allows creation of local control system and up to 4 modules can be connected/site. Internal battery backup and various I/O are included.
LinkTx G3 Comprehensive Remote Monitoring and Control via Text Messaging
Pittsford, NY: LinkTx G3 is a SMS based remote monitoring and control unit, allowing a GSM mobile phone or GSM enabled computer system to remotely monitor and control systems or equipment based at remote locations. Text messages can be sent to turn equipment on or off, change system parameters and request instant measurement and alarm information, sent directly to a mobile phone or PC.
With LinkTx G3, emergency conditions, temperature, voltage, current and digital readings can be sent to up to 16 GSM mobile telephone numbers and 4 number groups. The message format and the trigger conditions are fully user programmable. A powerful feature of the system is the ability to perform programmable local actions based on the value of any of the system parameters (measured values, or I/O states). Text message commands may be sent to the LinkTx G3 unit to perform functions such as setting mobile numbers to receive alert messages, setting alert threshold values for measured temperatures, voltages, currents and digital input states. Additionally, a number of digital outputs are available allowing remote control of external equipment.
The system is fully programmable remotely via SMS text messages, dialed connection, or locally using the serial RS232 interface. LinkTx G3 uses a built-in quad-band GSM cellular engine ensuring compatibility with any GSM network worldwide. For added reliability, the wall-mounted LinkTx G3 features internal battery backup.
Typical applications for LinkTx G3 include: plant and equipment monitoring, security systems, remote diagnostics, equipment alarm notification, temperature monitoring and control, asset protection, position monitoring, remote command and control, home automation, etc. You can even create your own local control system, e.g. temperature controller, with remote control capability and alarm and status reporting via SMS with just a few simple rule definitions. Or you could have a text message sent if a digital input changes state. A more complex scenario - but easy for LinkTx G3 - would be to send 3 different messages to 5 different numbers & turn on an output IF a measured temperature falls below a certain value AND digital line 2 is 5V AND the time is between 0300 and 0400.
LinkTx G3 weighs only 12 oz and features: 2 x 0-60VDC analog inputs, 2 x 0-300Amp DC current transducer inputs, 2 x temperature probe inputs, 4 x digital inputs, 1 x digital Output (change-over relay), 1 x LinkTx I/O module bus, 1 x RS232 local management port. LinkTx G3's I/O capabilities can be expanded with the addition of one or more LinkTx I/O Modules (up to four per site). Each LinkTx I/O Module provides additional I/O capabilities: a 0-20VDC analog input for supply monitoring, a 4-20mA input, 8 Digital inputs, 4 x 10A changeover relay outputs an RS485 serial port and an RS232 serial port.
LinkTx G3 is available from stock now at $459 each from Saelig Co. Inc. Pittsford NY. info@saelig.com. LinkTx I/O Modules are $149 each.
