Cleveland, Ohio Keithley Instruments, Inc. has expanded the Series 3700 system switch/multimeter and plug-in card family with the addition of two plug-in cards the Model 3724 dual 1X30 solid-state FET relay multiplexer card and the Model 3750 multifunction I/O card.
The Model 3724 dual 1X30 FET multiplexer card 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 long-life solid-state relays can be automatically configured into either a dual 1x30 or 1x60 multiplexer.
The card also features temperature measurement capability with automatic CJC sensors when used with the optional screw terminal accessory. The Model 3724 can be used in a variety of applications where speed and lifetime are important considerations such as for R&D and manufacturing in accelerated stress testing, production test, process monitor and control, data acquisition, and device characterization.
The Model 3750 multifunction I/O card features 40 digital I/O channels with high-current driver outputs that can sink up to 300 mA, allowing them to drive relays directly without any interface circuitry. The Model 3750 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 Model 3750 is suitable for production test applications where interaction with sensors and other mechanical/electrical translation devices are used.
Pricing: Model 3724 dual 1X30 FET multiplexer card is priced at $1,595 and the Model 3750 multifunction I/O card at $1,250.
Availability: Four to six weeks, after receipt of order.
