Offering broader support for switching configurations, the Model 3724 Dual 1X30 Solid State FET Relay Multiplexer Card and the Model 3750 Multifunction I/O card from Keithley Instruments, are plug-in cards added to the Series 3700 System Switch/Multimeter and Plug-in Card Family. The Model 3724 features scanning speeds of greater than 1,000 channels/second, including measurement, and switch-only scan rates greater than 1,200 channels/second. The card also offers 200 V, 0.1 A of switch/carry capacity with offset current of less than 10 nA. The solid state relays can be configured into either a dual 1 x 30 or 1 x 60 multiplexer. The card also features temperature measurement capability with automatic CJC sensors when used with the optional screw terminal accessory. This model can be used in a variety of applications where speed and lifetime are important considerations. The Model 3750 channels with high-current driver outputs that can sink up to 300 mA, allowing them to drive relays directly without any interface circuitry. This model also features two programmable analog outputs offering both voltage and current programmable isolated analog outputs including 0-20 mA, 4-20 mA, or +/-12 VDC. It also comes with four totalizers/counters with 32 bit resolution and is gated with a 1 MHz input rate. The device is suitable for production test applications where interaction with sensors and other mechanical and electrical translation devices are used.
