  • Connects to RS-232 (distance up to 50 feet)
  • 8 channels of 8 bit Analog to Digital (256 increments) for single-ended inputs
      or 4 channels of 8 bit fully differential inputs (256 increments) with ADC8-8RS232
  • 8 channels of 10 bit Analog to Digital (1,024 increments) for single-ended inputs
      or 4 channels of 10 bit fully differential inputs (1,024 increments) with ADC8-10RS232
  • 8 channels of 12 bit Analog to Digital (4,096 increments) for single-ended inputs
      or 4 channels of 12 bit fully differential inputs (4,096 increments) with ADC8-12RS232
  • Selectable reference voltage - allows for (0 to 3.3v), (0 to 4.096v), (0 to 5v) or user supplied voltage input ranges
  • Full technical support provided by on staff advisors
  • Commercial Grade reliability - engineered for continuous 24 hour industrial operation
  • Expandable to monitor up to 8 digital inputs or control up to 8 relays (or combinations) using the
    EX-8M expansion card or...
  • Expandable to control up to 128 relays, monitor 128 inputs (or combinations of relays and inputs) using EXM-16 or EXM-32 Relay I/O Expansion Modules
  • Expandable to also control Digital to Analog levels or monitor additional Analog to Digital channels - contact EECI support for more info
  • Compatible with Windows XP, Vista, Windows Server, Windows 7, Windows 8.1, Windows 10 and Windows 11
  • No complicated communication protocol - just one line of code is required to read all inputs (or control all relays) to greatly simplify software development. The RS-232 connection and all initialization is completely automated.
  • Use your own program to read, display and process the 8 analog inputs for any application or use the included software*
  • Source code examples included on CD in Microsoft Visual Basic.Net, Visual C#, C++, Python and others
  • LabVIEW compatible, includes LabVIEW VI, graphic software example and DLL library
  • Includes CD (or optional USB Flash Drive) with Data Logging Software, driver and user interface. Requires RS-232 cable (CC-DE9SP) and PS-5VDC-1000 wall adapter
    *Smartphone applications can vary, please contact EECI support to check compatibility for your device
