ABB SB510 3BSE000860R1

Product Overview

SB510 is a key backup power component in the ABB Advant Master distributed process control system. 3BSE000860R1 is defined as Backup Power Supply. The core function is to provide a brief but crucial DC power supply to the critical memory in the Advant Master system when the main AC power supply fails or is interrupted, in order to prevent program loss and critical data caused by sudden power outages.

In the field of industrial automation, unplanned downtime of DCS systems may lead to disastrous consequences. Although the main power supply of the system is usually guaranteed by a UPS, the SB510 provides the last line of defense. It integrates a 12V, 4Ah nickel-cadmium battery inside. When the main power supply fails, it can immediately and seamlessly switch to battery power to maintain the operation of key circuits such as CMOS RAM inside the controller, ensuring that the system can quickly and safely restart from the breakpoint after the main power supply is restored without having to re-download the entire control program. Thereby minimizing downtime and protecting the integrity of production data.

Product Functional Features

Dual-mode input, strong adaptability

The AC/DC compatible SB510 can accept 110-230V AC or 110-230V DC as the main power input. This enables it to be flexibly deployed in various factory environments, whether they are mainly powered by AC or have DC power supply systems.

Specialized battery management

The NiCd battery has optimized its internal circuit and is specifically designed for 12V, 4Ah nickel-cadmium. NiCd batteries are renowned for their high reliability, wide temperature range performance and long cycle life, making them highly suitable for industrial backup power applications. The SB510 not only charges the battery but also features overcharge protection and discharge management circuits to maximize battery life and performance.

When the main power supply voltage drops below the preset threshold, the switching circuit inside the SB510 can switch the load from the main power supply to battery power within microseconds, ensuring that the protected circuit does not experience any voltage interruption.

Ensure system integrity

In the Advant Master system, control logic programs are usually stored in RAM that requires continuous power supply. The backup power supply of SB510 ensures that these programs will not be lost even in the event of a complete power outage.

The alarm records, event sequences, accumulator data and other crucial information for accident analysis and production traceability generated during system operation also rely on SB510 for preservation.

Comparison of Advantages and Disadvantages

Advantages

Precise data protection effectively safeguards the most critical assets in the system - control programs and operational data - at the lowest cost and with the lowest complexity.

High reliability is achieved through industrial-grade components and proven NiCd battery technology, ensuring reliable operation at critical moments.

As a standard accessory of the Advant Master system, its installation and wiring are very simple and perfectly match the controller rack.

Disadvantage

NiCd batteries have a service life and will age over time and through charging and discharging cycles, with their capacity gradually decreasing. Regular inspection and replacement are required; otherwise, sufficient backup time may not be provided at critical moments.

NiCd batteries contain heavy metal cadmium and are classified as hazardous waste. Their disposal must comply with strict environmental protection regulations, which increases the cost and complexity of treatment at the end of their life cycle.

Compared with modern super capacitors or lithium battery solutions, NiCd batteries have a lower energy density and problems such as memory effect.
