With high-precision A/D and D/A channels, the DS1004 is a great fit for measurement and control applications in the fields of building automation (e.g. HVAC), process automation, lab work, etc.

Unlike many "remote I/O" products, the DS1004's capabilities are not limited to just relaying I/O data to a central server. Programmability in Tibbo BASIC and/or Tibbo C means that you can create systems where intelligent decisions are made in real time by the DS1004 itself.

The capabilities of the DS1004 are further expanded by two low-power relays and one simple RS232/485 port. This port can be used for connecting an auxiliary serial device, a card or barcode reader, or even additional DS10xx devices.

The DS1004 comes pre-loaded with an open-source Remote I/O Application for remote control/monitoring of the device's A/Ds, D/As and relays through a web browser or through Tibbo's AggreGate device management system. This application can be customized easily for any functionality desired.
