UL 508: Ratings and assumptions of certification File E189713 Volume: 2 Section: 5 Standards CSA C22.2 NO. 14-10 INDUSTRIAL CONTROL EQUIPMENT - Edition 11 - Revision Date 2011/08/01 UL 508 STANDARD FOR INDUSTRIAL CONTROL EQUIPMENT - Edition 17 - Revision Date 2010/04/15 Ratings Parameter Symbol Unit Value Primary involved potential V AC/DC 600 Max surrounding air temperature T C 105 A According to series primary Primary current I A P current Secondary supply voltage U V DC 5 C V Output voltage V 0 to 5 out Conditions of acceptability 1 - These devices have been evaluated for overvoltage category III and for use in pollution degree 2 environment. 2 - A suitable enclosure shall be provided in the end-use application. 3 - The terminals have not been evaluated for field wiring. 4 - These devices are intended to be mounted on a printed wiring board of end use equipment. The suitability of the connections (including spacings) shall be determined in the end-use application. 5 - Primary terminals shall not be straightened since assembly of housing case depends upon bending of the terminals. 6 - Any surface of polymeric housing have not been evaluated as insulating barrier. 7 - Low voltage control circuit shall be supplied by an isolating source (such as a transformer , optical isolator, limiting impedance or electro-mechanical relay). Marking Only those products bearing the UR Mark should be considered to be Listed or Recognized and covered under UL s Follow-Up Service. Always look for the Mark on the product.
