The DSAO120 (57120001-EY) is a multi-channel analog output module used to convert digital control signals from the automation system into analog electrical signals that can drive final control elements. Supporting both current (typically 4–20 mA) and voltage (e.g., 0–10 V) outputs, this module enables fine-tuned control over industrial processes. The unit features multiple output channels, robust diagnostics, and compact DIN-rail mount design, making it ideal for modern DCS architectures.
