AC, DC output pluggable solid state relays

Crydom's LifePlus ED series is designed for electromechanical relay (EMR) users looking to replace traditional 12 mm x 29 mm EMRs.

Crydom's new LifePlus ED series of ac and dc output pluggable solid state relays reportedly offer electromechanical relay users the opportunity to directly replace traditional 12 x 29 mm EMRs. Solid state relays apparently offer substantial performance advantages over traditional EMR switching solutions in many applications including significantly greater life expectancy (>100 million operations), contactless high speed switching eliminating contact bounce and resulting electrical noise, precise logic compatible control inputs, acoustically silent operation and high vibration resistance, among others. 

Available in a SPST N.O. configuration, the LifePlus ED series reportedly offers output ratings of either 3 or 5 amps rms at 24 to 280 V ac, or 5 amps dc at 1 to 48 or 1 to 80 V dc, all at 40 C ambient temperature. AC outputs reportedly incorporate Crydom's back-to-back SCR technology while dc outputs use high efficiency FETs, both technologies resulting in the lowest possible on-state power dissipation and high surge current ratings, for applications such as small motors, solenoids, heaters, and lamps. Optically isolated control inputs available include 3 to 15 V dc, 18 to 32 V dc, 48 to 72 V dc, 18 to 36 V ac and 90 to 140 V ac.

Crydom's LifePlus ED series relays are reportedly UL508 recognized for both general purpose and motor control applications and compliant to IEC 62314 LC-A resistive and LC-B inductive application requirements. They are also CE certified to the IEC Low Voltage Directive and compliant to the IEC EMC Directive. The LifePlus ED series relays are available in the industry standard 12 x 29 mm plug-in relay package and fit standard DIN rail and PCB mountable sockets, apparently allowing direct replacement of SPST N.O. EMRs in most applications.
