Keithley 7036 40 Channel Role Relay Switch Card

The Keithley 7036 is a 40-channel relay switch card engineered for integration into Keithley switching systems, delivering high-density signal routing for automated test and data acquisition applications. Built on Form A relay architecture, the 7036 provides independent 1-pole switching across 40 channels with extremely low contact resistance and minimal crosstalk, making it ideal for precision signal control in electronic and electrical testing environments. The card includes 10 digital inputs and 10 digital outputs with configurable logic levels, supporting complex switching and control logic within portable device test systems.
