Additional Accessories


  • Connects to RS-232 (distance up to 50 feet)
  • 4 or 8 channels of 15 bit Analog to Digital (32,768 increments) for single-ended inputs
    or 2/4 channels of 16 bit differential inputs (65,536 increments)
  • Built-in Instrument Amplifier with selectable high precision reference voltage - allows for...
    Standard Mode (8 (15 bit) or 4 (16 bit) channels):  (0 to 512mv), (0 to 1.024v), (0 to 2.048v),
       (0 to 2.5v), (0 to 5v) or user supplied reference (up to 0 to 5v) single ended voltage input ranges or
       differential ranges (+/-512mv), (+/-1.024v), (+/-2.048v), (+/-5v), (+/- user supplied)
    Mixed Mode (3 or 6 channel):  2 single ended 15 bit inputs and 1 16 bit differential input per bank
    High Gain (4 channel) Mode:  (0 to 256mv), (0 to 128mv), (0 to 64mv), (0 to 32mv) or (0 to 16mv)
       in (15 bit) single ended or
       (+/-256mv), (+/-128mv), (+/-64mv), (+/-32mv) or (+/-16mv) in (16 bit) differential
  • High Precision Programmable Instrument Amp modes are scaled to provide a precise and uniform measured voltage per increment
  • 8 Channel (Dual Bank) version allows two separate voltage reference selections (of the 10 voltage ranges) and permits simultaneous use of single ended inputs with differential inputs (or four fully differential HG inputs)
  • High Gain inputs allow direct connection of sensors, transducers or devices with low level outputs
  • Selectable high precision mode provides greatly improved noise rejection with greater precision when high sample rates are not required
  • May be special ordered in 12 or 16 channel converters - contact EECI support for more info
  • Full technical support provided by on staff advisors
  • Commercial Grade reliability - engineered for continuous 24 hour industrial operation utilizing Texas Instrument's world renown advanced analog technology
  • 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 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 4 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 Data Logging Software, driver and user interface. Requires cable and power adapter (PS-5VDC-1000)
    *Smartphone applications can vary, please contact EECI support to check compatibility for your device
