Keithley Instruments has added to its 3700 system range of switch/multimeter and plug-in cards with the Model 3724 Dual 1X30 Solid State FET Relay Multiplexer Card and the Model 3750 Multifunction I/O Card.

The new cards are designed to support a wider variety of switching configurations in order to keep up with the demands of increased testing complexity. 

The Model 3724 Dual 1X30 FET Multiplexer Card features scanning speeds of greater than 1,000channels/s, including measurement, and switch-only scan rates greater than 1,200 channels/second.

The card also offers 200V, 0.1A of switch/carry capacity with offset current of less than 10nA.

The Model 3750 Multifunction I/O Card features 40 digital I/O channels with high-current driver outputs that can sink up to 300mA, allowing them to drive relays directly without any interface circuitry.

The Model 3750 also features two programmable analogue outputs offering both voltage and current programmable isolated analogue outputs including 0-20mA, 4-20mA, or +/-12Vdc.

It also comes with four totalisers/counters with 32-bit resolution and is gated with a 1MHz input rate.
