Entry Level
Where teaching labs, student projects and first bench setups start. Analog and digital modules side by side — eight to twenty-four lines, powered entirely from the USB port, at the lowest cost per station in the range.
- 8 analog or 24 digital lines
- 12/14-bit · up to 48 kS/s
- No external supply needed

Front and top views of the module. Enclosure, terminal style and silkscreen vary by model — confirm the exact part number before ordering.
Why this tier
-
Analog and digital in one tier
The USB-6008 and USB-6009 measure; the USB-6501 switches and counts; the USB-6525 drives real loads through solid-state relays. Same driver, same software, same page in the manual.
-
Two analog modules, one wiring diagram
The USB-6008 and USB-6009 share the same pinout, terminal block and driver calls. Start on the 12-bit part and move to the 14-bit part later without touching your harness.
-
Genuinely bus powered
Draws under 80 mA from the port. On a laptop in the field there is nothing else to carry.
-
OEM board versions
The analog modules are available without the enclosure, for embedding in your own instrument or test fixture.
Models in this tier
