Quick verdict
If your industrial PCS, SCADA, or edge-control system needs a spare control board and you want the lower listed price, the Apex Industrial Tech 31-04115-08 Edge Variants PCB Control Board at USD 199.99 gives you a clearly identified PCB with the model and MPN in the title. If the job calls for a legacy ISA graphic controller for a CNC or automation display, the Egan 470590 Graphic Controller Board at USD 254.15 is the one to consider. The $54.16 difference between them reflects condition and intended role.

Product notes
Apex Industrial Tech 31-04115-08 Edge Variants PCB Control Board
The Apex board carries the condition label New - Open box, with the model 31-04115-08 and MPN 30-04376-02 in the title. It is a PCB, not a graphic controller, so it fits buyers looking for a replacement control board for an edge-variant application. The open-box condition means the original packaging has been opened, which is the tradeoff you accept for the lower listed price. If you already have a system that uses this exact model, the board gives you the identity information you need. The main limitation is that the condition is open-box rather than sealed retail, and its listed role is limited to a control PCB rather than a display-oriented ISA card.
Egan 470590 Graphic Controller Board ISA Video Card Industrial CNC PCB
The Egan board is described as used, tested, and clean with no visible physical damage after being removed from industrial equipment. Its model and MPN are both 470590, and its type is Graphic Controller Board with an ISA edge connection. That makes it the board for legacy video display or CNC machine interface duties in this pair. The controller platform is listed as Proprietary Industrial Video System, so it is best matched to a compatible legacy setup. The higher listed price goes with the graphic-controller role and the tested label in the title. The limitation is that it is a used board, and the proprietary video system narrows the field of compatible systems.
Final choice by use case
If you need a lower-priced PCB for an edge-variant control application, start with the Apex Industrial Tech 31-04115-08 Edge Variants PCB Control Board. If you need an ISA video/graphic card for a CNC or industrial display, the Egan 470590 Graphic Controller Board is the one to choose. Your system's interface determines the answer: a control PCB for edge variants, or a video/graphic controller for legacy industrial displays.
