Description
IMDSO14: Product Overview
The ABB IMDSO14 is a 16-channel digital slave output module designed specifically for ABB’s INFI 90 and Symphony distributed control systems (DCS). As a critical interface between the central controller and field devices, it enables precise control of industrial processes by converting digital signals from the DCS into electrical outputs that drive actuators, solenoids, relays, and other field equipment.
Role in Automation Systems:
Positioned as a “slave” module, the IMDSO14 receives commands from the INFI 90/Symphony main controller and transmits them to field devices. It acts as a bridge between the high-level control logic (e.g., PID loops, sequence control) and the physical layer, ensuring that control signals are executed accurately and reliably. This role is pivotal in industries where process stability and precision are paramount, such as power generation, chemical processing, and manufacturing.
Core Functionality:
-
16 Independent Output Channels: Each channel can be configured to switch 24VDC or 48VDC loads, providing flexibility for different field device requirements.
-
High Isolation: With 2500V AC isolation between channels and the logic circuit, the module protects the DCS from electrical noise and voltage spikes generated by field devices—critical for maintaining signal integrity in harsh industrial environments.
-
Short-Circuit Protection: Built-in protection prevents damage to the module or field devices in case of a short circuit, enhancing system reliability.
-
Compact Design: Measuring approximately 100mm (W) × 120mm (H) × 40mm (D), the module fits easily into control cabinets, minimizing space requirements.
Platform Benefits (INFI 90/Symphony):
The IMDSO14 leverages ABB’s legacy INFI 90 and Symphony platforms, which are renowned for their robustness and scalability in industrial automation. Key benefits include:
-
Seamless Integration: The module is fully compatible with INFI 90/Symphony systems, reducing integration complexity and ensuring plug-and-play functionality.
-
Scalability: Multiple IMDSO14 modules can be added to the system to expand output capacity, supporting growing industrial operations.

Core Features & Customer Value
1. High Isolation for Harsh Environments:
The IMDSO14’s 2500V AC isolation voltage ensures that electrical noise from field devices (e.g., motors, solenoids) does not interfere with the DCS logic. For customers, this means more reliable signal transmission and fewer false alarms—critical for maintaining process stability in industries like chemical processing or power generation.
2. Flexible Output Configuration:
With support for 24VDC and 48VDC loads, the module can be adapted to a wide range of field devices without requiring additional hardware. For example, a customer can use the same module to control 24VDC solenoid valves and 48VDC relays, simplifying inventory management and reducing costs.
3. Compact Design for Space Efficiency:
The module’s small footprint (100mm × 120mm × 40mm) allows it to fit into crowded control cabinets, saving valuable space. This is particularly valuable for customers upgrading existing systems where cabinet space is limited.
4. Robust Protection Mechanisms:
Short-circuit protection and overcurrent limiting prevent damage to the module or field devices, reducing maintenance costs and downtime. For customers, this means greater peace of mind and lower total cost of ownership.
