• Connects to USB - Powered from USB port
• 4 or 8 channels of 11 bit Analog to Digital (2,048 increments) for single-ended inputs
  or 2/4 channels of 12 bit differential inputs (4,096 increments) with ADC-4U11/ADC-8U11
• 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) with ADC-4U15/ADC-8U15
• 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
• Reliable and stable data guaranteed or your purchase refunded
• Commercial Grade Reliability - engineered for continuous 24 hour industrial operation utilizing Texas Instrument's world renown advanced analog technology combined with advanced USB connectivity by Prolific Technology Inc, a world leader in USB interfacing
• 8 Channel version allows two separate voltage reference selections (of the 6 voltage ranges) and permits simultaneous use of single ended inputs with differential inputs
• High Gain version available with (10) selectable voltage ranges of 0 to 5V down to 0 to 16mv allowing direct connect of sensors and devices with low level outputs. See this link for more info: ADC-4U15HG
• Both 11/12 bit and 15/16 bit versions may be special ordered in 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
• Expandable to monitor up to 16 digital inputs or control up to 16 relays using EX-8M Expansion Modules or...
• Expandable to control up to 144 relays, monitor 144 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 USB connection and all initialization is completely automated.
• Use your own program to read, display and process the 4 analog inputs (and control relays) for any application or use the included software
• Source code examples included 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 Windows device driver and Android Apps* on CD (click Delivery Options above for USB Flash Drive). Requires USB type B cable (CC-USBB1 or CC-USBB6)
*Smartphone applications can vary, please contact EECI support to check compatibility for your device
