Product Overview

The ABB 216DB61 is an advanced binary input/output and tripping unit, designed for critical control applications such as ABB’s Procontrol P13 excitation platform. It combines digital signal acquisition with high-speed tripping logic, enabling real-time fault detection and protective action. With its six tripping relays and dual contact configuration, the module is designed for fast, redundant fault isolation, making it essential for mission-critical automation systems.

Built for harsh industrial environments, the 216DB61 offers short-circuit protection, redundant power support, and compatibility with standard industrial communication protocols like Modbus TCP/IP and PROFINET. It is widely used in power generation, substation automation, and high-speed process control systems, where uptime and system protection are paramount.

Key Specifications

Typical Applications

The 216DB61 module is widely used in turbine protection systems, substation fault isolation, and emergency shutdown circuits. Some typical applications include:

• Turbine Protection: Monitors binary signals from sensors and switches to trigger protective relays during overcurrent, overspeed, or thermal faults.

• Substation Automation: Provides fault isolation and tripping to ensure that faults are quickly detected and cleared in electrical substations.

• Chemical Facilities: It supports redundant control architectures in power plants and chemical facilities, ensuring continuous operation even during partial system failures.

With its high-speed response and robust relay design, the 216DB61 is ideal for environments where real-time fault protection is essential, such as power generation, high-speed process control, and substation automation.
