Overview

The A6120 operator workstation is part of Emerson's family of industrial visualization solutions, optimized for use with DeltaV and Ovation DCS platforms. Its 12.1-inch TFT LCD provides a clear, sunlight-readable display with wide viewing angles, ensuring operators can view process graphics and alarms from any position. The fanless design eliminates moving parts, reducing maintenance and increasing reliability in dusty or vibrating environments. The workstation supports a wide range of input voltages and includes isolated I/O for safe integration into control systems.
