Field Control Layer Device
Inividaul LCD Touch Control Panel
【
Description
】
DST28U individual LCD touch control panel attached with temperature or
humidity sensor is designed to work with any type of AIRTEK
DAC/DSC series controller which has MSnet port. It is a two-wire RS485
communication transmission interconnection with the controller. It may
facilitate the user by graphically to access, examine, setting, change and
confirm each kind of control parameter value from DAC/DSC controller,
for example temperature value, humidity value, devices operation
status, and alarm messages, enable output points start/stop, changing
the temperature and humidity setting values,etc. DST28U has a 2.8
inches TFT LCD touch screen
and Simplified / Traditional Chinese /
English display subtitles function, four function keys, build in with a 32-bit
high performance microprocessor. User can use BACsoft software or
HMIkit to edit screen pages, even corporate image or promotion leaflet
can be loaded to the screen when in non operation mode, This not only
enhance the added value of products but also enhance the effectiveness
of corporate image advertising.
【
