Introduction
CtrlTechDaily reports that the ABB DO571 digital output module is now available for industrial automation systems. This module belongs to the S500-eCo series and provides eight relay outputs for reliable switching in control applications. The DO571 offers flexible voltage support and a compact footprint, making it a strong choice for modern factory floors.
Key Features
The ABB DO571 delivers eight digital outputs via relay contacts, supporting both 24VDC/24VAC and 100-240VAC at 2A per channel. This dual-voltage capability allows the module to work with a wide range of actuators and loads without additional signal conditioning. The module carries an IP20 protection rating, suitable for installation in clean, enclosed control cabinets.
Its compact dimensions — 34 mm width, 135 mm height, and 75 mm depth — save valuable panel space. The net weight of only 0.12 kg simplifies mounting and reduces mechanical stress on DIN rails. These features help engineers design more efficient and space-optimized automation systems.
Technical Specifications
The DO571 operates with a product ID of 3ABD10094783 and the type designation DO571. It supports relay outputs rated for 24VDC/24VAC or 100-240VAC at 2A, providing flexibility for both low-voltage and line-voltage applications. The module measures 34 mm in width, 135 mm in height, and 75 mm in depth, with a net weight of 0.12 kg.
The IP20 protection level ensures safe operation in environments free from dust and moisture ingress. The module is part of the PLC-AC500-eCo product family, ensuring seamless integration with ABB's S500-eCo I/O system. These specifications make the DO571 suitable for a variety of discrete control tasks.
Applications
The DO571 excels in material handling systems where it controls conveyor motors, diverters, and solenoids. Its relay outputs handle both AC and DC loads, simplifying wiring and reducing component count. In packaging machinery, the module manages actuators for sealing, labeling, and sorting stations.
Assembly lines benefit from the DO571's ability to switch 100-240VAC loads directly, eliminating the need for interposing relays. The compact size allows dense I/O placement in control panels, which is critical for large-scale production lines. Process control applications also use the module for valve actuation and alarm signaling.
