DASO110: Product OverviewThe DASO110 is a 16-channel digital output module within ABB’s S800 I/O family, designed for switching DC loads in process automation and control applications. This module serves as an interface between the control system and field actuators, converting logic-level signals from the controller into switched 24V DC outputs that operate devices such as solenoid valves, relays, contactors, motor starters, and indicator lights. Installed in an S800 I/O station, its primary function is to execute control commands from the processor by energizing or de-energizing field circuits based on the application program.The module provides sourcing outputs, meaning it supplies positive voltage to the load when activated. Each channel is individually protected with short-circuit and overload protection, preventing a fault on one output from affecting the others. The design includes electrical isolation between the field side and the system side, protecting the sensitive control system electronics from voltage spikes and electrical noise that can occur in industrial environments. Status LEDs for each channel provide immediate visual indication of output state, facilitating troubleshooting and maintenance.

Core Features & Customer ValueThe module’s 16 output channels provide high density in a compact form factor, reducing cabinet space requirements compared to using multiple modules with fewer channels. For system integrators, this means lower hardware costs and simplified system design. The individual channel protection ensures that a fault in one output (such as a short circuit) does not disrupt operation of the remaining channels, significantly improving system availability and simplifying troubleshooting.The sourcing output configuration (PNP) is compatible with most industrial sensors and actuators, simplifying integration with existing equipment. The status LEDs for each channel provide immediate visual feedback for troubleshooting, allowing maintenance personnel to quickly identify active outputs without requiring additional test equipment. The module’s robust design ensures reliable operation in industrial environments with electrical noise and vibration.Typical ApplicationsIn material handling systems, the DASO110 controls conveyor motor starters, sorting gates, and package diverters. The high channel count allows a single module to control multiple devices along a conveyor line, while the fast response time ensures precise timing for sorting operations.In water treatment plants, the module operates solenoid valves for chemical dosing, controls pump motors through motor starters, and activates alarm horns and indicator lights. The individual channel protection prevents a single valve or motor fault from disabling the entire output module.
