Keithley 3740 - General Purpose Card with 32 Independent Channels

The Keithley 3740 offers 28 general-purpose form C channels that are ideal for routing power or other control devices. For higher power applications of up to 7A, four additional high current forms A channels are provided.

If any general-purpose signal requires routing to the Series 3700A mainframe backplane, terminal blocks are located on the card, which is enabled with jumpers. Custom configurations can be created with the user-accessible terminal blocks. For additional protection, an onboard temperature sensor will notify the mainframe when the card’s operating temperature exceeds 70°C, compromising system specifications.

The Keithley 3740 uses two 50-pin male D-sub connectors for signal connections. For screw terminal connections, use the detachable Model 3740-ST accessory.
