Crydom – New solid-state AC / DC output pluggable relays replace 12mm x 29mm EMRs (DP4R60D20)

Crydom’s new LifePlus ED Series of AC and DC output pluggable solid-state relays offer electromechanical relay (EMR) users the opportunity to directly replace traditional 12mm x 29mm EMRs with proven solid-state relay technology.

Solid-state relays (SSRs) 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 many others.

Available in a SPST N.O. configuration, the LifePlus ED Series offers output ratings of either 3A or 5A rms at 24 to 280VAC, or 5ADC at 1 to 48VDC or 1 to 80VDC, all at 40C ambient temperature. AC outputs incorporate Crydom’s proven Back-to-Back SCR technology while DC outputs utilize high-efficiency FETs, both technologies result in the lowest possible on-state power dissipation and high surge current ratings which make the SSRs an attractive choice for applications such as small motors, solenoids, heaters and lamps. Optically-isolated control inputs available include 3 to 15VDC, 18 to 32VDC, 48 to 72VDC, 18 to 36VAC and 90 to 140VAC, says the company.
