ABB DAO01 P3717-4-0369629 Analog Output Module

Number of channels: 8 independent analog outputs.

Output accuracy: ±0.1% (typical), resolution 16 bits.

Voltage output: ≥10kΩ (0-10V);

Current output: ≤500Ω (4-20mA).

Response time: <10ms.

Isolation characteristics: Channel-to-channel isolation voltage 2500V AC (1 minute), channel-to-system isolation voltage 1500V DC.

Module power supply: 24V DC ±10%;

Output loop power supply: supports external 24V DC power supply.

Protection level: IP20

Bus interface: PROFIBUS DP V1 (9.6kbps to 12Mbps), supports integration with ABB AC800M or third-party DCS systems.

Protocol compatibility: Configuration and diagnosis through FDT/DTM tools, support MODBUS RTU.

Output frequency: 50kHz.

Operating temperature: -20°C to +70°C (fanless design, natural convection cooling).

Anti-interference ability: Complies with IEC 61000-6-2 industrial electromagnetic compatibility standards, and can resist high-frequency harmonics and radio frequency interference.

Hardware redundancy: ABB DAO01 supports dual power input (24V DC redundancy) to ensure continuous operation of the system in the event of a single point failure.

Fault isolation: Each channel is electrically isolated independently to avoid short circuit propagation, and optional fuses are supported (2.0A).

Mechanical life: Contact mechanical life ≥10^7 times, electrical life ≥10^5 times (under full load conditions).

2. Intelligent diagnosis and remote monitoring

Real-time status monitoring: 4-color LED indicators display power, communication, overload, and short circuit status to quickly locate faults.

Self-diagnosis function: ABB DAO01 has built-in overcurrent/overvoltage protection, which automatically cuts off the output and sends an alarm signal through the bus when abnormal.

Remote configuration: ABB DAO01 remotely adjusts the output type and contact mode through ABB Ability™ or third-party configuration software.

PROFIBUS PA address setting: Supports local DIP switch or system tool configuration, and the factory default address is 126 (reset at startup).

3. Hazardous area adaptability

Explosion-proof design: ATEX certified models support Ex nA II T3 Gc (gas) or Ex tb IIIC T135°C Db (dust), suitable for non-continuous hazardous environments such as petrochemical, oil and gas.

Intrinsically safe interface: Can connect intrinsically safe actuators to ensure safe signal transmission in hazardous areas.

Zone 1/Div.1 restrictions: Current output mode must be specified in advance when ordering and cannot be changed later.

4. Flexible scalability

Modular architecture: Can be mixed with other modules of the ABB S900 series to meet complex I/O requirements.

Multi-protocol support: Can be expanded to PROFINET, Modbus TCP and other protocols through gateway modules, compatible with heterogeneous systems.

Petrochemical and chemical industry: In the temperature control of reactors and the pressure regulation of distillation towers, the high-precision analog output (±0.1%) of DAO01 can directly drive the regulating valve, reducing the intermediate signal conversion level.

Papermaking and metallurgy: Used for coating machine tension control and continuous casting machine crystallizer cooling water valve control, supporting redundant configuration to ensure continuous production.

2. Energy and electricity

Wind power and photovoltaic: In the grid-connected switch control of converters and the switching of reactive power compensation devices, the fast response characteristics (<10ms) improve the stability of the power grid.

Substation automation: Cooperate with ABB RELION protection relay to realize remote switch control and fault isolation of smart grids.

3. Infrastructure

Water treatment system: Control aeration fan inverter and regulating valve opening, optimize sewage treatment efficiency, and support MODBUS protocol and SCADA system integration.

Smart building: Link with ABB i-bus system to adjust central air-conditioning chillers and lighting systems to achieve energy management.
