Sony Corporation EPM7032-15EY Photomos I Board

Refurbished Sony SDC-1 Photomos I/O Board, model EPM7032-15EY (also listed as EBA0063 and EY), operates from a 24 VDC supply (DC24VIN) and provides PhotoMOS-based input/output switching for the SDC-1 system. This module serves as the controller’s external I/O interface, enabling isolated, solid-state switching for connections to external load circuits while protecting the main unit from voltage spikes. The board is identified by the EPM7032-15, EY, and EBA0063 part numbers within Sony’s SDC-1 spare-parts ecosystem. As a refurbished component, it offers a cost-effective option for maintaining existing SDC-1 configurations that require 24 V logic and Photomos I/O functionality. Common applications include integrating additional I/O points in Sony SDC-1 deployments where compact form factor and isolation are advantageous for reliable switching of external circuits.
