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 situa-
tions where budget-conscious users require flexibility, stability and a high
level of isolation protection for their data acquisition system.
