ABB DSDO 131 is a 16-channel Digital Output Board for 800xA/Advant systems, with 24VDC output, 0.5A per channel. It drives actuators/relays, has isolation & diagnostics, ensuring reliable industrial control.
Technical Description of DSDO 131 (Part Number: 57160001-KX)
1. Product Overview and Core Identity
The DSDO 131 (part number: 57160001-KX) is a 16-Channel Digital Output Unit designed by ABB, belonging to the S100 I/O module family. It serves as a versatile interface component in industrial control systems, translating digital control signals from upper-level controllers (e.g., ABB 800xA DCS, Advant MasterPiece 200) into relay-driven outputs to control a wide range of AC/DC field devices. With support for both 0–240 V AC and DC loads, and high load capacity (48 W DC / 720 VA AC), this unit is ideal for applications such as industrial lighting control, motor starter activation, valve actuation, and other medium-to-high power switching tasks in manufacturing, energy, and process automation sectors.
Notably, the DSDO 131 is exempt from the RoHS Directive (2011/65/EU) under Article 2(4)(c), (e), (f), and (j), as validated in ABB’s EU Declaration of Conformity (document: 3BSE088609). This exemption applies to equipment used in critical industrial process control systems, aligning with its role in supporting robust, long-service-life automation infrastructure. Classified as a "Digital Output Unit," it leverages relay-based switching to ensure reliable isolation between control signals and high-voltage/current field loads.
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, wiring, and grounding—critical for safety when switching high AC/DC voltages. Ensure the enclosure provides adequate ventilation to dissipate heat from relays during prolonged operation.
Load Compatibility: Verify that connected loads do not exceed the unit’s maximum capacity (48 W DC / 720 VA AC). Overloading may cause relay damage, overheating, or electrical hazards. For inductive loads (e.g., motors, solenoids), use external surge suppression (e.g., MOVs, flyback diodes) to protect relay contacts.
Regulatory Documentation: Retain ABB’s EU Declaration of Conformity (3BSE088609) for regulatory audits, as the product is RoHS-exempt.
End-of-Life Disposal: Dispose of the unit in compliance with local WEEE regulations (Category 5) to minimize environmental impact. Relay components may require separate handling per local electronic waste guidelines.
