Keithley 7013-C Isolated Relay Switch, 20-Channel

The Keithley 7013-C is a 20-channel isolated relay switch card designed for integration into Keithley switching system mainframes. Each channel employs high-quality electromechanical relays configured as Form A (Normally Open) switches, delivering independent galvanic isolation and superior signal integrity across demanding automated test environments. The module supports switching voltages to 300 VDC / 250 VAC with make and carry currents of 2 A and break current of 1 A at resistive loads.
