RM481-E Product Information

RM481-E and RM481B Identification

The photographed board carries RM481- with an E label at one edge, while RM481B and BC886A001G51A appear in another identification area. Record all markings when comparing replacements. Retain the final A in the printed board number and record the separate A label independently. These markings do not establish interchangeability with every RM481 variant.

Resistors, Connectors and Connection Positions

Compare the two upright white resistors, the long black connector, the cream multipin connector and the smaller white connector. Check the large plated holes, including the positions marked P, N, L1, L2 and L3, against the original board. The yellow transformer and blue rectangular component provide additional visual references for layout matching.

Fitment Confirmation and Supply Scope

Provide front, rear and side photographs, the complete host model and fault information. Confirm connector keying, connection positions, component clearance and revision requirements with your technician. Component markings should not be used as the rating of the complete PCB. Supply covers the quoted board assembly; cables and accessories are included only when specified.

Testing and Dispatch

REACO CNC provides a testing video before shipment. Confirm actual-unit condition, availability and test scope with your quotation. Send the required quantity and delivery country for shipping options.
