ABB CI840A 3BSE041882R1 COMMUNICATION MODULE

2.Interface type: Dual-port RS-485 (DB9 connector)

3.Redundancy: Supports dual-port line redundancy, master redundancy requires dual modules

4.Operating temperature: -25℃ to +50℃

5.Protection level: IP20 (indoor installation)

6.Power supply voltage: 24 VDC (±10%)

7.Power consumption: Typical 4.3 W (24 VDC, 190 mA)

2.Redundant design: The dual-port RS-485 interface supports line redundancy to ensure seamless switching when the communication link fails. With redundant power supply modules, system-level high availability can be achieved, which is suitable for key fields such as petrochemicals and electricity.

3.HART pass-through function: ABB CI840A 3BSE041882R1 supports parameter configuration and diagnostic data transmission of HART protocol devices and is compatible with HART 7 protocol. For example, in a water treatment system, the calibration information of the pH sensor can be read directly through CI840A.

4.Hot-swap and modular expansion: ABB CI840A 3BSE041882R1 supports module replacement during operation to reduce downtime. Through the TU847 module terminal unit, 32 I/O modules can be expanded.

5.Environmental adaptability: ABB CI840A 3BSE041882R1 has a wide temperature range of -25℃ to +50℃ and IP20 protection level, meeting the needs of extreme environments such as deserts and polar regions.

2.Energy system: wind turbine status monitoring and microgrid load balancing in wind farms.

3.Process control: closed-loop control of temperature and pressure of chemical reactors (requires FOUNDATION Fieldbus gateway).

4.Building automation: integrating HVAC systems and energy management platforms to optimize building energy efficiency.
