Aesa FC-981N Mass Flow Controller 5 SLM

Aesa RXKO-2 Relay, identified by RXKO-2 with RK 318 and 424-AH codes, is a general‑purpose industrial relay from ASEA’s Combiflex line used to switch circuits in control panels and automation systems. The RXKO-2 designation appears in vintage ASEA catalogs and in online marketplaces under RK 318 with a 424-AH suffix (and, in some listings, 424-AN), reflecting its role as a legacy OEM component that still turns up in spare‑parts inventories. This model is associated with the broader RXKO family, which encompassed relays designed for dependable operation within typical control circuit applications of its era. Because it represents a historic relay series, units bearing the RXKO-2 suffix are commonly encountered in legacy installations and are sought after by engineers maintaining equipment that originally used ASEA RXKO relays.
