SRC DEVICES DIP 14 SERIES REED RELAYS MSS2 s MSS7 s PRMA s DSS7 s PRME s MVS2 s MVS7 DESCRIPTION SRC Device’s epoxy molded DIP 14 Series offers a variety of contacts and schematics to meet the needs of a wide range of applications. It features the MVS2/MVS7 models designed for high reliability. The MSS2/7 DIPs are 1-Form-A relays equipped with the MYAD® all-position mounting switch. With switching up to 50 Watts and a 4000V isolation option, the DIP 14 Series is a relay package that allows for automatic insertion directly on PCBs as well as insertion into standard 14 Pin DIP sockets.
