(ex: kr48s5-1000p) to order negative logic on-off c ontrol add the suffix ?r? (ex: kr48s5-1000r) 7. the industrial ?i? suffix for the 2:1 input version is more efficient; therefore, it can be operated in a more extensive tem perature range than ?standard? and ?i? suffix 4:1 input versions. to order industrial temperature range (-40c ~ +85 c) add the suffix ?i? to the par t number (ex: kr48s5-1000i) 8. heat sink is optional, consult factory. 9. an external filter capacitor is required if the module has to meet en61000-4-5. the filter capacitor wall industries suggest s: nippon chemi-con ky series 220 f/100v esr 48m ? .
