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 normally
closed (Form B) versions with either
AC or DC input (coil) control.
Manufactured in Crydom’s ISO 9002
Certified facility for optimum product
performance and reliability.
