ABB 57160001-NF DSDO 115 Digital Output Unit DSDO115

Description

The ABB 57160001-NF DSDO 115 (DSDO115) Digital Output Unit is a dedicated module for distributed control systems (DCS), designed to convert digital signals into output signals to control external industrial devices such as relays, valves, and motors. Built on ABB’s proprietary FBP bus technology, it features a simple, flexible bus system that supports easy protocol switching: users can replace the bus adapter on the same FBP bus base to switch between protocols like Profibus DP or DeviceNet, with automatic recognition of changes and no special user configuration required. The AC500 controller can also operate as a fieldbus slave via an FBP bus adapter.

Key physical specifications include dimensions of 2x25x24.5 cm and a weight of 0.32 kg. For system expansion, up to 10 I/O modules can be connected locally to the CPU (with firmware version V1.2 or higher), while distributed sub-stations support up to 7 I/O modules. The module is part of a family that includes both analog and discrete I/O options, with user-configurable I/O types for flexible deployment. It delivers reliable performance for industrial automation applications in manufacturing, process industries, and power sectors, with core functions focused on stable, efficient digital signal output for external actuator control.
