Special Shielded Cable for Noise Reduction

The PCL-10168 shielded cable is specially designed for the PCI-1780

for reducing noise. Its wires are all twisted pairs, with input signals and

output signals separately shielded, providing minimal cross talk between

signals and offering the best protection against EMI/EMC problems.
