Satisfies the Need for Isolation Protection
The PCI-1713U provides 2500VDC optical isolation protection 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.
