The Keithley 7013-S is a 20-channel 2-pole independent switch card engineered for signal routing in automated test systems. Each channel provides Form A (Hi, Lo) switching with sub-ohm contact resistance and exceptional isolation, making it suitable for low-level signal switching and general-purpose routing applications. The card integrates directly into Keithley Model 7001 and 7002 mainframes via screw terminal connectivity.
