Description

Product Overview

The DI01 is a 16‑channel low‑voltage digital input module for the ABB Symphony Plus SD DCS platform. It captures discrete status signals from field contact devices including valve feedbacks, limit switches, relay contacts and interlock sensors. Each channel provides independent galvanic isolation to suppress noise and ground loop interference. This card supports 1 ms resolution Sequence of Events (SOE) timestamping and configurable debounce, which delivers precise event logging for fault analysis and post‑trip review. It mounts on HBS01‑FPN or VBS01 base units and supports hot‑swap replacement without process shutdown, suited for power, chemical, pulp and petrochemical continuous control systems.
