ABB Bailey P-HB-AOT-1500C100 Analog Output Module

ABB Bailey P-HB-AOT-1500C100 Harmony Analog Output Module is a Harmony-series I/O block that provides sixteen independent 4–20 mA DC outputs for precise analog control in Bailey/ABB Harmony INFI 90 systems. The sixteen channels are non-isolated, and each channel accepts an engineering demand value from the controller, which the module scales to the 4–20 mA range and converts to current; per-channel readback and software compensation help ensure signal accuracy and channel integrity. In operation, the AOT-1500 family is designed for robust industrial use, automatically compensating for supply variations so that the output current remains within specification and enabling reliable long-term control of actuators, valves, and other analog devices; field calibration is not required. This variant, P-HB-AOT-1500C100, fits Harmony I/O backplanes and supports multi-channel applications such as valve positioning, pump control, and other analog setpoints in process and manufacturing environments, delivering consistent signal behavior across a broad range of operating conditions.
