Keithley 7020D

This Digital I/O Interface Cards feature 40 independent digital inputs and 40 independent outputs to provide high density, cost effective digital monitoring and control.

Versatile design and configuration I/O options provide compatibility with a wide range of signals and loads.

Internal pull up resistors on the inputs provide level shifting so microswitches can be monitored directly.

Each input is protected against overvoltage, so logic levels up to 42V peak can be monitored.

Digital outputs can drive relatively high current devices, including solenoids, relays, and small motors, without the need for additional control circuitry.
