A relay assembly comprises a vital relay used in a vital circuit and configured to be rack-installed in an equipment room in a railroad case or a railroad housing for providing a modular solid-state current-limiting. The relay assembly further comprises a plurality of vital relay contacts to which a current flow is restricted by a single supply solid-state current limiter. The relay assembly further comprises a relay socket base assembly coupled to the vital relay. The relay socket base assembly includes a relay socket base including a plurality of vital relay contact prongs, a plug assembly including a plurality of printed circuit board (PCB) mounted contact terminals, and a plurality of contact terminals that provide a connection between the plurality of vital relay contact prongs and the plurality of printed circuit board (PCB) mounted contact terminals. The relay assembly further comprises an ancillary electrical control module.
