Featuring state-of-the-art Surface
Mount Technology, these SPST-NO
relays deliver proven reliability in the
most demanding applications.
Output consists of an SCR AC switch
and is available in zero-cross, random
turn-on (phase controllable) and ver-
sions with either AC or DC input (coil)
control.
Manufactured in Crydom’s ISO 9001
Certified facility for optimum product
performance and reliability.
