Keithley KPCI-3160 Parallel Digital I/O Boards

  • Compatible with Industry Standard Solid-State Relays
  • Bi-Directional I/O
  • High-Current Driver Capability


The Keithley KPCI-3160 Parallel Digital I/O Boards offer a wide range of functionality for applications as diverse as digital I/O and process control to prototyping and parallel communications. They provide 96 TTL-level digital I/O lines that can be used for digital control of processes and monitoring of the status of switches, contacts, or other control points. All digital I/O lines can be accessed simultaneously by the hardware and software. These lines also provide high-current driver outputs for sinking (64mA) and sourcing (15mA). This allows them to drive relays directly without any interface circuitry.

The digital I/O lines of the KPCI-3160 are divided into four 24-bit groups, each of which is further divided into 3 separate 8-bit ports (PA, PB, and PC). These ports can be set independently under software control as inputs or outputs. In addition to operating as a standard 8-bit data port, the third port (PC) can be subdivided into 2 half ports of 4 bits each. The PA, PB, and PC ports can always be read/write accessed, regardless of their initial configuration, without affecting external signal levels. All ports default as inputs upon initial power-up or reset conditions. The KPCI-3160 has a high-output current of 15mA (source) and 64mA (sink), enabling direct control of LEDs, solid-state I/O modules, and relays. The KPCI-3160 also supports external interrupts on pins 24 and 25. This interrupt capability allows external clocking and latching of digital I/O data.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
