ABB XVC768115 3BHB7211R115 Digital Input/Output (I/O) Module
16xDI/16xDO 24VDC Module for ABB Symphony Plus DCS - Hot - Swappable with Short - Circuit Protection
1. Core Overview
The ABB XVC768115 3BHB7211R115 is a high - performance digital I/O module designed for the ABB Symphony Plus distributed control system (DCS), dedicated to reliable digital signal acquisition and control command execution in harsh industrial settings. It features 16 isolated digital input (DI) channels and 16 isolated digital output (DO) channels, all 24VDC - compatible, to connect with sensors, switches, actuators, and other field devices. The module supports hot - swapping for online maintenance without system shutdown, and is equipped with short - circuit and overload protection to safeguard itself and connected equipment, ensuring uninterrupted operation in power, petrochemical, and manufacturing applications.
• Core Role: Digital signal acquisition, control command output, field - system signal exchange for Symphony Plus DCS
• Key Specs: 24VDC DI/DO; 16 DI (sink/source), 16 DO (sink, 2A per channel); 24VDC power; -20°C to +60°C operation
• Model Info: XVC768115; Ordering Code: 3BHB7211R115; Symphony Plus DCS Digital I/O Module
• Reliability: Hot - swappable; short - circuit/overload protection; IP20; CE/UL certified
2. I/O & Protection Features
This module offers 16 isolated DI channels for on/off signal detection and 16 isolated DO channels for driving actuators, each DO channel rated at 2A for direct load control. Inputs and outputs are fully isolated to prevent cross - talk and ground loops, and outputs include short - circuit and overload protection to cut off current during faults, protecting the module and field devices. It supports fast input response (≤1ms) and output switching (≤2ms) for time - critical control loops, and diagnostic LEDs for quick status checks (channel on/off, module power, fault alarms).
• Digital Inputs: 16 channels, 24VDC, sink/source; isolated; response time ≤1ms
• Digital Outputs: 16 channels, 24VDC, sink; 2A per channel; short - circuit/overload protection
• Isolation: Channel - to - channel, channel - to - backplane isolation (500V AC)
• Diagnostics: LED indicators for channel status, power, and fault; event logging for remote troubleshooting
3. Integration & Installation
The 3BHB7211R115 seamlessly integrates with ABB Symphony Plus DCS via the system backplane, supporting IEC 61850, Modbus RTU/TCP, and PROFIBUS for data exchange with SCADA/DCS. Its hot - swap capability enables module replacement without system shutdown, minimizing downtime. The compact DIN - rail/panel - mount design fits standard control cabinets, and the plug - in terminal blocks simplify wiring and maintenance, reducing installation time by up to 30%.
• Communication: Symphony Plus backplane; IEC 61850, Modbus RTU/TCP, PROFIBUS compatible
