Nkọwa LS I/O Experion na Nka na ụzụ data, EP03-110-400, V2, January 2012 7 Relay and Expandable Interface Modules (XIM) na-enyekwu mgbanwe maka ụdị mmepụta pụrụ iche IOM (TC/TKODD321 na TC/TK- ODA161). Emepụtara ha iji bulie ịdị irè nke ngwa ndị ọrụ chọrọ ọkwa kọntaktị mmepụta karịa 2 A. Ịkwọ nnukwu ibu ruru 10 A maka ngwa dị ka ndị na-amalite moto ugbu a ga-ekwe omume site na iji ụdị ọsọ agbagharị RTP ndị a. Na mgbakwunye, modul relay na-enye ụzọ isi kewapụ isi ihe mmepụta.
