Technical Description of DSDO 115A (Part Number: 3BSE018298R1)
1. Product Overview and Core Identity
The DSDO 115A (part number: 3BSE018298R1) is a 32-Channel Digital Output Board designed by ABB, belonging to the S100 I/O module family. It serves as a critical component in industrial control systems, converting digital control signals from upper-level controllers (e.g., ABB Advant Controller 450, MasterPiece 200) into electrical outputs to drive field devices such as relays, contactors, solenoids, or indicator lamps. Operating at 24 VDC with a maximum current rating of 0.5 A per channel, this board is optimized for low-to-medium power industrial applications, ensuring reliable signal transmission and device control in sectors like manufacturing, energy, and process automation.
Notably, the DSDO 115A is exempt from the RoHS Directive (2011/65/EU) under Article 2(4)(c), (e), (f), and (j), as specified in ABB’s EU Declaration of Conformity (document: 3BSE088609). This exemption applies to equipment used in industrial process control systems, aligning with its role in critical automation infrastructure.
2. Key Notes for Installation and Use
Mounting: Designed for rack mounting within ABB S100 I/O enclosures; follow ABB’s S100 I/O Installation Manual for proper alignment and wiring to avoid electrical faults.
Load Compatibility: Ensure connected field devices do not exceed the 0.5 A per channel current rating to prevent damage to the board or loads.
Exemption Documentation: Retain ABB’s EU Declaration of Conformity (3BSE088609) for regulatory compliance audits, as the product is RoHS-exempt.
WEEE Compliance: When decommissioned, dispose of the board in accordance with local WEEE regulations for electronic waste, as it falls under Category 5 (Small Equipment).
