This unit
The Keithley 7020 and 7020-D Digital I/O Interface Cards deliver high-density digital signal management for automated test systems. Each card provides 40 independent digital inputs and 40 independent digital outputs - 80 bits total - in a compact, cost-effective form factor. The 7020 uses a 96-pin DIN connector, while the 7020-D features dual 50-pin D-sub connectors optimized for frequent industrial connections. Both variants support monitoring and control applications requiring extensive digital signal routing without additional interface logic.

Key Features
Selectable internal or external pull-up voltage via jumper configuration
Per-channel current limiting and overvoltage protection
Low saturation voltage enables efficient driving of inductive loads
DIN and D-sub connector options for different mechanical integration needs
Typical Applications
Equipment control and device activation in production test environments
Digital signal monitoring in multi-unit automated test systems
Relay and solenoid switching without external driver circuits
Compatibility & Integration The 7020 integrates into test systems requiring modular digital I/O expansion. Connector type selection (DIN vs. D-sub) determines mechanical fit and cable management strategy.
