  • Connects to RS-232 (distance up to 50 feet)
  • 4 channels of 10 bit Digital to Analog (1,024 increments in output level) with DAC4-10RS232
  • 4 channels of 12 bit Digital to Analog (4,096 increments in output level) with DAC4-12RS232
  • 4 channels of 16 bit Digital to Analog (65,536 increments in output level) with DAC4-16RS232
  • Selectable reference voltage - allows for 0 to 3.3v, 0 to 5v or user supplied voltage output ranges
  • Available with high precision voltage reference pre-installed. Allows for (0 to 1.2v), (0 to 2.048v - .5mV per increment), (0 to 2.5v), (0 to 3v) or (0 to 4.096v - 1mV per increment) output ranges
    Contact EECI support for more info
  • Add the CO-420T 4-20mA Transmitter for RS-232 controlled 4-20mA current loop transmitter
  • Full technical support provided by on staff advisors
  • Expandable to monitor up to 8 digital inputs or control up to 8 relays using the EX-8M expansion cards 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 monitor Analog to Digital channels or control additional Digital to Analog levels - contact EECI support for more info
  • Compatible with Windows XP, Vista, Windows 7, Windows 8.1, Windows 10 and Windows 11
  • Android Compatible - Use with your Android tablet or phone - connects directly to USB port or monitor over network or Wi-Fi
  • No complicated communication protocol - just one line of code is required to control all analog levels (or control all relays) to greatly simplify software development. The RS-232 connection and all initialization is completely automated.
  • Use your own program to control the 4 analog output levels 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 Data Logging Software, driver and user interface on CD (or optional USB Flash Drive). Requires RS-232 cable (CC-DE9SP) and PS-5VDC-1000 wall adapter.
