SPECIFICATIONS

Power Supply....................... 5 volts DC - powered from USB port (USB version only)
Operating Temp. Range......
-40° C to +85° C
Serial Data Protocol............. 75 to 6,000,000 baud - auto detect (defaults to 115,200 baud)
Full duplex operation (data bits, parity, stop bits will auto detect)
Maximum Sampling Rate...... 100 samples per second or better
Analog Inputs....................... 4 single-ended inputs (15 bit resolution) - no missing codes
or 2 fully differential inputs (16 bit resolution) - no missing codes
(15 bit resolution will divide your measurement range into 32,768 different increments)
(16 bit resolution will divide your measurement range into 65,536 different increments)
Input Impedance.................
Common mode better than 6 mega ohm (see page 11 and 12)
Voltage Input Range............
Selectable at: 0 to 256 millivolt, 0 to 512 millivolt, 0 to 1.024 volt, 0 to 2.048 volts,
0 to 4.096 volts and 0 to 6.144 volts (with 5 V max)*
*the voltage resolution per increment can be determined by dividing one of the
above reference voltages by 32,768.
Expansion Capability............ expandable to control up to 144 relays/inputs (or combinations) using
EX-8M, EXM-8, EXM-16 or EXM-32 Relay I/O Expansion Modules

  • Page 2 Please set-up and test the ADC-4U15 as follows (Windows XP*, Vista, Windows Server, Windows 7, 8.1, browse to the Windows Driver folder and double click on setup.exe). A desktop icon for the ADC-4U15 will be created. Windows 10 or Windows 11) *service pack 3 When installing the ADC-4U15 device driver on a Windows XP or Vista computer, double click on setup.exe in the XP-...
  • Page 3 4.096 volts DC). You may use the analog test circuit shown below to provide the test voltage. When using a 9 volt (2) Verify that the Prolific USB to Serial Comm Port entry is the com port used by your ADC-4U15. You may do this by smoke detector battery, use a multimeter to check for the correct voltage since the voltage can go well over the watching the entry in Device Manager and unplugging your ADC-4U15 from your computer USB port.
  • Page 4 'To use these example, copy the code module (supplied on your CD) to a sub called readInputs(). From the toolbox, and then clicking Apply. Available com ports are drag (4) labels and a timer control to your form. Insert the following code into the timer sub. The (4) ADC-4U15 updated by clicking the "Com Port" button under analog inputs are displayed in labels 1 through 4.
  • Page 5 SINGLE ENDED ANALOG VOLTAGE INPUTS The ADC-4U15 may be set to accept (2) fully differential inputs in place of the (4) single ended inputs. The differential voltage input range is determined by the reference setting as shown on the previous page. The differential input signal Voltages up to hundreds of volts may be divided down to the 5 volt range by using a simple resistance divider as connects to terminals 1 and 2 for differential channel 1 and terminals 3 and 4 for differential channel 2.
  • Page 6 FOR ON/OFF STATUS The ADC-4U15 defaults to a 0 to 4 volt input range (setup allows input ranges as low as 0 to .25 volts). When the input voltage range is required to be lower, (such as with a watt transducer or load cell) an external instrumentation Fuse or Limiting Resistor (330 ohm 1 watt) amplifier must be used to amplify the input signal to the 0 to 4 volt input range of the ADC.
