DTI 1320 Series

The DTI 1320 is one of a family of low-cost solutions to the implementation of field devices that require NTCIP conformant communication. The small size and powerful performance of the DTI 1320 controller make it the perfect engine to control signs, traffic count systems, weather stations, cameras or any custom application where NTCIP communication is required.

Four serial ports are provided (2 ports are jumper- selectable to be RS232 or RS485), as well as digital inputs and outputs and analog inputs. The module is provided with NTCIP communications built in, so the only custom development required is the interfacing of the module to the applicable field sensor or output device. An Ethernet port provides a powerful optional connection for high speed communication, and an on board temperature sensor is provided as standard.

The DTI 1320 incorporates a “flash disk” (8 MB standard) for storage of any logging data or other information. This makes it a perfect choice for applications where on board data storage is required.
