Our UMDDA series of USB analog-output modules combine the best features of an
I/O card and terminal panel in a compact package -- D/A without opening opening
your PC! The modules provide 16-bit resolution differential channels with 0-10V
and ±10V output ranges. UMDDA 04H, 08H, and 16H models source or sink 3.5mA in
either output range. They are compatible with both USB 2.0 and 1.1 ports, and
include a 32-bit TTL-level counter/timer. Ranges of all analog-output channels
can be individually programmed. In addition, all 8 digital I/O channels can be
individually programmed as input or output. Power is via the USB cable.
xxHA models add a 0-20mA output current range. Our UMDDA xxHC models have the same two voltage ranges (no current range), but their voltage ranges have a current capacity of 40mA.
