Additional Accessories


  • Connects to RS-485 (distance up to 4,000 feet)
  • 12 channels of 8 bit Analog to Digital (256 increments) for single-ended inputs
    or 6 channels of 8 bit fully differential inputs (256 increments) with ADC12-8RS485
  • 12 channels of 10 bit Analog to Digital (1,024 increments) for single-ended inputs
    or 6 channels of 10 bit fully differential inputs (1,024 increments) with ADC12-10RS485
  • 12 channels of 12 bit Analog to Digital (4,096 increments) for single-ended inputs
    or 6 channels of 12 bit fully differential inputs (4,096 increments) with ADC12-12RS485
  • Selectable reference voltage - allows for (0 to 3.3v), (0 to 4.096v), (0 to 5v) or user supplied voltage input ranges
  • Includes built-in Data Logger which may be used to log pressure, weight, fluid flow, energy usage/demand, temperature, voltage, current, solar array data or data from any of thousands of devices with analog outputs.
  • 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 using the
    EX-8M expansion card or...
  • Expandable to control up to 136 relays, monitor 136 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 11, Windows 10, Windows Server, Windows 8.1, Windows 7, Windows Vista and Windows XP
  • 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-485 connection and all initialization is completely automated.
  • Use your own program to read, display and process the 12 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, Microsoft ASP.Net and others
  • LabVIEW compatible, includes LabVIEW VI, graphic software example and DLL library
  • Includes CD (or optional USB Flash Drive) with Windows device driver and user interface. Requires power adapter (PS-5VDC-1000)
    *Smartphone applications can vary, please contact EECI support to check compatibility for your device
