Reliance Electric 847434-1R Industrial Relay Module

Reliance Electric 847434-1R is a printed circuit board (PCB) PLC module used in Reliance Electric control systems in the RE/UCC1 family. Also cataloged as 802286-62A, it appears in listings as the RE PCB PLC Module and is associated with NP1200-1, indicating its role within the broader RELIANCE ELECTRIC RE PLC module lineup. This compact board is described as a plug-in component that carries user logic and interfaces with other controller hardware in legacy automation cabinets, enabling control sequences, interlocks, and discrete I/O tasks typical of industrial machinery. In reseller listings, the 847434-1R is identified as a PCB PLC module from Reliance Electric's control ecosystem; one vendor notes refurbished condition, reflecting availability through repair and remanufactured channels. For buyers maintaining older Reliance Electric installations, this part serves as a replacement or upgrade within the NP1200-1 reference framework, supporting continued operation of legacy control networks without a full system redesign. Because the part is cross-listed under 802286-62A, distributors may list it under that alternate code, aiding searchability in spare-part inventories for legacy automation equipment.
