ABB DSDP170K02 3BSE019925R1

• Humidity Tolerance: 5% to 95% relative humidity (non-condensing)
• Mounting Compatibility: Designed for installation in ABB Advant OCS standard subracks (e.g., Advant Controller 450/460 subracks)
• Backplane Interface: Complies with ABB Advant OCS backplane communication protocols for seamless integration with system controllers

Functional Features

• High Signal Integrity: Equipped with built-in noise filtering circuits to suppress electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring accurate detection of weak digital signals.
• Diagnostic Capabilities: Provides real-time self-diagnosis and channel-level fault detection. Faults such as open circuits, short circuits, or overvoltage on input channels are transmitted to the central controller, enabling timely maintenance.
• Hot-Swappable Design: Supports hot swapping (when used with compatible ABB subracks and controllers), allowing module replacement without shutting down the entire control system, minimizing production downtime.
• LED Status Indicators: Each input channel is equipped with a dedicated LED indicator (green for normal signal, red for fault) and a module-level power LED, enabling on-site visual inspection of operational status.
• Wide Compatibility: Fully compatible with ABB Advant OCS controllers (e.g., AC 450, AC 460) and configuration software (e.g., Control Builder), supporting easy parameter setting and signal mapping.

Application Scenarios

• Process Industry: Used in oil and gas, petrochemical, chemical, and pharmaceutical plants to collect digital signals from field devices such as limit switches, pressure switches, level switches, and emergency stop buttons, supporting process monitoring (e.g., tank level status, valve open/close feedback).
• Power Generation: Integrated into thermal power plants, hydropower stations, and renewable energy (solar/wind) control systems to capture status signals from generator auxiliary equipment, circuit breakers, and protection relays, ensuring safe and stable operation of power units.
• Manufacturing Industry: Applied in automotive, electronics, and machinery manufacturing assembly lines to collect signals from photoelectric sensors, proximity switches, and conveyor belt status detectors, enabling automated production line control and fault alarming.
• Water and Wastewater Treatment: Used in water treatment plants and sewage treatment facilities to monitor the status of pumps, valves, and filter systems (e.g., pump start/stop feedback, filter clogging signals), supporting automated process control and water quality management.
• Marine and Offshore: Compatible with marine-grade environmental requirements (when paired with suitable enclosures), used in offshore platforms and shipboard control systems to collect digital signals from navigation equipment, safety systems, and auxiliary machinery, ensuring reliable operation in marine environments.
