Satisfies the Need for Isolation Protection

The PCI-1713 provides optical isolation protection of 2500 VDC

between the inputs and the PC bus to protect the PC and peripherals

from damage due to high voltages on the input lines. It is ideal for the

situations where budget-conscious users require flexibility, stability

and a high level of isolation protection for their data acquisition

system.
