Product Overview

DSDI120AV1 is universal 16‑channel digital input module for ABB AC800M control systems. It accepts wide‑range 15‑240 V AC or DC field inputs without hardware jumper modification. Galvanic group isolation protects rack electronics from field‑side surges. Supported by Profibus‑DP‑V1 fieldbus communication. Suitable for petrochemical, power and marine automation projects. Available as refurbished and surplus spare parts for legacy ABB‑system maintenance.

Application Notes

‑ Insert module into AC800M S100 I/O rack. ‑ Verify actual field signal voltage falls within module universal input range. ‑ ESD handling required during hot‑swap or replacement. ‑ Typical deployment: power‑plant, petrochemical DCS discrete‑input spare‑part stocking.
