ABB DSDO 115 is a digital output module (Digital Output Module) produced by ABB. It is part of ABB's Advant OCS (Operator Control System) series control system and is used to control and operate external devices.

The DSDO 115 module can receive digital signals sent by the control system and convert them into corresponding output signals for driving external devices such as actuators, relays, motors, etc. This module is commonly used in industrial automation and process control systems to achieve remote control and operation of equipment.

The DSDO 115 module has multiple output channels, each of which can provide a digital output signal. The module is usually installed in a rack-mounted control system and communicates and connects with other modules through a digital bus.

The DSDO 115 has 32 channels, which means it can provide 32 independent digital output signals at the same time.
