Product Overview
The DSAI130 (part number 57120001‑P) is a high‑performance analog input board used in industrial automation and process control systems. It is designed to capture multiple analog signals from field sensors (voltage, current, differential inputs) and convert them into digital values for use by a control system.
This board is particularly suited for high‑precision measurement applications: it supports differential‑input analog signals, offers a high level of accuracy, and is built to perform reliably in challenging industrial environments. It is used in control racks or I/O modules in advanced process or safety systems.

Product Description
The DSAI130 analog input board allows a control system to interface with a variety of analog field sensors—such as voltage outputs, current loops, and differential inputs—by providing 16 channels of analog signal acquisition. Each channel operates in differential mode, reducing the impact of common‑mode voltages and external noise. With a high accuracy rating (±0.025%), the board is suitable for precise measurement tasks in critical process control or safety applications.
Its large form‑factor, rack‑mount format is typical for process automation I/O systems. The board is designed as a spare part for advanced controller platforms, ensuring seamless replacement or upgrade in existing systems. The differential architecture and high precision make it ideal in applications where sensor accuracy, reliability and noise immunity are essential.
Product Applications
-
Process automation plants (chemical, petrochemical, oil & gas) requiring precise analog measurement.
-
Safety systems and advanced controllers (MasterPiece, Safeguard) where accurate analog inputs are essential.
-
Utility and power generation plants monitoring sensors such as temperature, pressure, flow via analog signals.
-
Large control‑rack I/O systems where analog input density and performance matter.
-
Retrofit or upgrade of older systems where a high‑accuracy analog input board is required.
