The 40-121-011 provides 16x 2:1 multiplexers in a single slot PXI module and designed to provide an isolation resistance in excess of 1013Ω. It has been designed to ensure high isolation resistance through the use of switched guards, making it ideal for low level measurements and semiconductor test.

The 40-121 series is fitted with ruthenium sputtered reed relays, these offer very long life with good low level switching performance and excellent contact resistance stability. Spare reed relays are built onto the circuit board to allow easy maintenance with minimum downtime.
