Bailey PHBDIO4000S200 Termination Base

The Bailey PHBDIO4000S200 Termination Base is the dedicated wiring termination platform for the DIO 4000 digital input I/O family, providing a stable foundation for field connections and proper alignment of the DIO 4000 modules inside automation cabinets. This part is cataloged as PHBDIO4000S200, with references to DIO 400 and DIO 4000SPS00HF and an associated catalog identifier of 6642920A1, enabling precise ordering and cross-reference in ABB/Bailey and legacy ASEA BOVERI documentation. As a digital input termination base, its function is to terminate and organize incoming signal wiring from field devices for the DIO 4000 series, contributing to signal integrity, reliable performance, and easier maintenance in industrial control panels. Historically documented in ABB/ASEA Boveri catalogs and now referenced within Bailey product lines, PHBDIO4000S200 forms part of a modular I/O approach that supports straightforward expansion and consistent mechanical interfaces across compatible input modules.
