  • Connects to RS-232 (distance up to 50 feet)
  • 4 channels of 11 bit Analog to Digital (2,048 increments) for single-ended inputs
      or 2 channels of 12 bit differential inputs (4,096 increments) with ADC4-11RS232
  • 4 channels of 15 bit Analog to Digital (32,768 increments) for single-ended inputs
      or 2 channels of 16 bit differential inputs (65,536 increments) with ADC4-15RS232
  • Built-in Instrument Amplifier with selectable high precision reference voltage - allows for
    (0 to 256mv), (0 to 512mv), (0 to 1.024v), (0 to 2.048v), (0 to 4.096v) or (0 to 6.144v*) voltage input ranges which are scaled to provide uniform voltage per increment        *caps at 5v
  • Both 11/12 bit and 15/16 bit versions may be special ordered in 8, 12 or 16 channel converters - contact EECI support for more info
  • 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 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 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-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*
