Keithley 7164M
Scanner Card with Mercury Wetted Contacts 400mohm
Description
This unit is a 20 channel, 2 pole scanner card featuring relays with mercury wetted contacts for high reliability, current switching capacity, and bounceless operation.
Mercury wetted relays also ensure consistent contact resistance of less than 400mohms over rated life of more than 1 billion closures (cold switching), or 100 million closures at maximum signal levels. Contacts are rated for resistive loads of 30VA
This unit is designed for use as a one of twenty channel selector.
Standard 50 pin D connectors and terminations to twisted pair ribbon cable simplify assembly and interconnects, reducing system integration and maintenance costs.
Key Points
High reliability combined with and bounceless contact closure
High density, low cost scanning
Easier interconnect and cabling
