Product Details

The DSAI130 57120001‑P is a compact Multi‑channel Analog Input Module for ABB Advant Master DCS platform, it acts as core Field Signal Acquisition Board for collecting process analog signals from industrial site.

It provides 16 analog input channels, mainly compatible with 4‑20mA and 0‑20mA standard current signals from transmitters. 12‑bit high‑precision A/D converter completes analog‑to‑digital conversion. Group‑based galvanic isolation effectively suppresses interference brought by field grounding loop and improves signal stability in harsh industrial environment. Collected digital signals are transmitted to main CPU through rack backplane bus for control algorithm calculation.

LED indicators on front panel show module operating status and channel fault information. Built‑in diagnosis function can detect open‑circuit, over‑range and hardware abnormal conditions of each channel, and upload alarm information to DCS host system. It supports channel parameter configuration through Advant engineering tool.

Adopting standard rack‑slot mechanical structure, it can be installed together with CPU, communication boards and other I/O modules in one control rack. Widely deployed in thermal power, petrochemical, pulp‑paper and chemical process industries. It is essential signal acquisition hardware for analog point expansion, field signal reconstruction and defective analog input module replacement for legacy Advant Master automation projects.
