ISOLATION
The FD-11601 provides channel-to-channel isolation. Input signals on each channel are
conditioned, buffered, and then sampled by an ADC. Each AI channel provides an
independent signal path and ADC, enabling you to sample all channels simultaneously. The
FieldDAQ device provides overvoltage protection for each channel; refer to the
FD-11601
Specifications
for more information about overvoltage protection.
Voltage Input Connectors
The FD-11601 features eight 5-pin A-coded M12 connectors: Bank 1 connectors 0 through 3
and Bank 2 connectors 0 through 3. The following figure shows the pinout of a voltage input
connector.
