Inductive load: 250V AC/5A (power factor 0.4) or 30V DC/5A (time constant 7ms).

Response time: <10ms (contact action time), <5ms (release time).

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

Module power supply: 24V DC ±10% (redundant power supply support);

Contact power supply: supports external 24-250V AC/DC power supply (need to match the load type).

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, supports MODBUS RTU.

Environmental adaptability

Operating temperature: -20°C to + 60°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.

1. High reliability industrial design

Hardware redundancy: ABB ARC093A V1 supports dual power input (24V DC redundancy) to ensure continuous operation of the system in the event of a single point failure.

Fault isolation: ABB ARC093A V1 has independent electrical isolation for each channel to prevent short circuit propagation and supports optional fuses (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 ARC093A V1 has built-in overcurrent/overvoltage protection, which automatically cuts off the output and sends an alarm signal through the bus when abnormal.

Remote configuration: Remotely adjust the output type and contact mode through ABB Ability™ or third-party configuration software.

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 be connected to intrinsically safe actuators to ensure safe signal transmission in hazardous areas.

4. Flexible scalability

Modular architecture: can be mixed with other modules of the ABB S900 series (such as AI, DI, DO) to meet complex I/O requirements.

Multi-protocol support: ABB ARC093A V1 can be expanded to PROFINET, Modbus TCP and other protocols through gateway modules, and is compatible with heterogeneous systems.

Petrochemical and chemical industry: In the control of reactor stirring motor and valve interlock protection, the high contact capacity (30A) of ARC093A V1 can directly drive the contactor and reduce the intermediate relay 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.

Wind power and photovoltaic: In the control of converter grid-connected switch and switching of reactive power compensation device, 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 grid.

3. Infrastructure

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

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