Configuring for Isolated Digital I/O
An industry-standard isolated digital I/O peripheral, like the Opto 22 16-Position
Single-Channel Mounting Rack, is a 50-pin connection. The connector is either a
card edge or a header connector. Do not connect pins 1 and 49 on the Opto 22
rack connector.
For example, the Opto 22 rack, PB16C, uses a card edge connector; PB16H uses
a header connector. They both have the same pinout for a ribbon cable. Both can
accommodate up to 16 single-channel I/O lines.
A cable designed to connect up to six ports to three Opto 22? racks is available
from Keysight Technologies, either as Option 022 when ordering the Keysight
E1458A, or as Keysight part number E1458-61604. Figure 2-7 shows the
connections from six ports to three racks.
