ABB DDO01 Key features
High Channel Density: 32 outputs in one module reduce rack space and wiring complexity.
Dual Voltage Flexibility: Supports both 24 VDC and 230 VAC, accommodating diverse actuator types.
Watchdog Protection: Built-in timer resets outputs on communication loss, ensuring failsafe operation.
Wide Temperature Range: –25 °C to +70 °C, suitable for extreme industrial conditions.
Seamless Freelance Integration: Plug-and-play into Freelance backplane for minimal configuration.
Performance comparison
Model | Type | Channels | Suitable Application |
DDO01 | Digital Output | 8 | Basic discrete output control |
DDO02 | Digital Output | 16 | Larger systems requiring more outputs |
DDI01 | Digital Input | 8 | Reading machine signals and device status |
Summary：
DDO01 fits well for standard output control tasks. DDO02 is more suitable for output-heavy systems, while DDI01 is essential for monitoring external input signals in the same automation setup.
