1. Product Attributes
| Attribute | Details |
|---|
| Product Model | DA701F (Order No.: 3BDH000371R0001) |
| Product Type | Industrial-grade digital-analog hybrid I/O module, compatible with the ABB Freelance S700 I/O system. It provides hybrid signal processing capability of 16DI+16DO+4AI, supports multiple types of industrial signals, and acts as a core signal acquisition and execution component for process control |
| Core Purpose | Serving as a hybrid signal I/O node of the Freelance system, it collects on-site switch status (e.g., valve position, motor start/stop) and analog parameters (4-20mA/0-10V signals such as temperature, pressure, flow rate, etc.), and uploads them to the main control system; meanwhile, it receives control commands and drives actuators such as contactors and solenoid valves via DO channels. It supports channel-level status indication and fault diagnosis, adapting to the discrete-continuous hybrid control requirements of small and medium-sized installations |
| Typical Positioning | Different from pure digital/analog modules, it focuses on centralized hybrid signal processing, suitable for industrial scenarios that require simultaneous monitoring of switch status and analog parameters. It reduces the number of modules and cabinet space, balancing system cost and integration efficiency |

5.2 Safe Operation and Maintenance Specifications
- Installation and wiring must be performed by professional personnel. Before operation, disconnect the system power supply and load circuit, and confirm no voltage exists before disassembly and assembly to avoid electric shock or module damage.
- DI/DO wiring must match terminal specifications; shielded cables should be used for AI signals with the shielding layer grounded at a single point to prevent signal distortion caused by interference.
- Regularly check the module temperature, terminal tightness and channel status. In case of channel faults or signal drift, replace the module in a timely manner and troubleshoot load faults.
