This unit
The Keithley KPCI-PDISO8A is a PCI bus isolated digital I/O board engineered for industrial data acquisition and control applications. It delivers eight optically isolated digital inputs and eight relay outputs - five Form C relays and three Form A relays - with galvanic isolation up to 60V channel-to-channel and channel-to-chassis. The board protects against voltage spikes and ground loops through optical isolation and on-board transient protection, making it suitable for harsh industrial environments with sensors, actuators, and external devices.
