**SPI control signals: Data, Clock, Blank, Latch
The MM1200 is a 6-channel SPST high-performance signal relay that can be used for high-density signal switching applications in both AC and DC circuits and is meant to replace electromechanical signal relays or reed relays. Typical applications range from medical equipment, DC switch matrices/multiplexers, to test & measurement equipment.
The MM1200 is capable of 1.0 A per channel steady state, and delivers low on-state contact resistance and high off-state isolation with >3 billion switching cycles and <10µs switching times.
Each switch is Normally Open (NO) and individually controlled by a digital serial-to-parallel Interface. An external +5 VDC logic supply and high voltage +79 VDC bias source are required for the operation of the internal switch driver.
