Functional features
1. High-speed real-time signal acquisition
ABB DDI01 accurately captures the changes in switch signals (such as equipment start and stop, valve switch) with a response time of ≤1ms to ensure the immediate execution of production line control instructions
2.Industrial-grade environmental adaptability
With a metal housing and wide temperature range design (-25°C to +60°C), ABB DDI01 is resistant to vibration, dust and electromagnetic interference, and is suitable for harsh scenarios such as substations and oil platforms.
3.Flexible interface and multi-protocol compatibility
Supporting TTL/CMOS signal input and RS-485, DeviceNet communication, ABB DDI01 can be seamlessly connected to PLC and DCS systems (such as Siemens and Rockwell) to achieve cross-platform integration.
4. Modular safety design
500VAC electrical isolation and redundant power supply interface between channels, ABB DDI01 automatically protects against overvoltage/overcurrent to ensure continuous operation of the system
Application scenarios
Power equipment monitoring: Collect circuit breaker status, protection device signals, and provide real-time feedback to the DCS system
Production line automation: Detect robot arm position switch, conveyor belt start and stop, and link PLC control process
Building intelligent control: Connect fire alarm and lighting switch signals to achieve centralized management of building equipment
Water treatment system: Monitor pump and valve switch status, and link flowmeter to achieve closed-loop control
