Sensata Technologies CKRD4810 Contactor

CKRD4810-10 is a Sensata Technologies (Crydom) CKR Series solid-state relay (SSR) designed to switch AC loads with a 10 A continuous rating, housed in the CKR family’s slim 22.5 mm DIN-rail mount package. The device accepts a 4–32 VDC control input, enabling direct interface with PLCs and other logic-level controllers, and it uses back-to-back SCR output to control AC loads without mechanical contacts. CKR Series devices feature a LED input status indicator, AC or DC control input, and switching behavior that can be zero-voltage turn-on for resistive loads or instantaneous turn-on for inductive loads, depending on model and load conditions. Note that CKRD4810-10 is listed as obsolete by Sensata, with a discontinued-product cross-reference guiding replacements within the CKR family; for exact load voltage range, pinout, and compatible replacements, consult Sensata's CKR datasheet and the discontinued products cross-reference.
