YUAA Specifications (continued)
Specification
Exists internally between the processor and the IONet ports to break ground loops, using high
resistance barriers
Operation is guaranteed only when channel terminals are connected to signal voltages between 20 to
-11 volts with respect to COM. For voltages outside this range, an external resistor may be required for
correct operation. Refer to the section
Signals above 24.5 or below -13 V with respect to COM will affect performance across other channels
and could cause long term degradation of the performance. Voltages beyond ± 28 V are clamped by
transorbs for protection.
