Hardware
The hardware of the evaluation units is
available in a number of different
variations, adapted to suit all types of
user requirements. Each variation is
distinguished by a specific combination
of hardware elements. Below are the
hardware elements for the
µP-ASD in LDG housing. Other hardware elements are also available: see
data sheet Hardware.
