June 20, 2011 - TPD-280U now has a real time clock to schedule events like heating, cooling or lighting a room based on time. TouchPad PLCs come with HMIWorks—a free programming development environment that allows a user to program in C Language or Ladder Logic. Many demo programs are available to aid development and help cut down on time to market. TouchPads come with RS-485 or Ethernet communication and support Modbus RTU or Modbus TCP respectively.
They are perfect for building automation and are available in 2.8” versions that fit in electrical outlets. They can be used as touch screen interfaces for lighting control, gas detection, HVAC systems, restaurant automation and more.
TPD-280 is communicable over RS-485 and Modbus RTU and has a 2’8” TFT full color display. . TPD-283 is communicable over Ethernet and Modbus TCP. TPD-283U features a real time clock for scheduling.
TPD-430 has a 4.3” display and RS-485 communication. They are designed to survive in harsh environments and can sustain -20ºC to 70ºC operating temperatures. TouchPad Touch Screen PLCs work with SCADA software since they communicate over common protocols like Modbus RTU and Modbus TCP which most software supports.
