I/O Interface
Section 10A
10A-61
Features
High resolution -- 16 bit input and 14 bit output converters provide
accurate control capabilities.
Backplane powered -- No external power supply required, reducing
system cost.
User selectable inputs -- Configurable per channel for current or voltage
inputs.
Input channel filtering -- Rejects high frequency noise that couples into
an analog input signal.
Image maps directly into the 1746I adapter.
Isolation -- All analog modules are isolated from each other and from
the backplane.
