GE IC693ACC335 вспомогательный блок аккумуляторных батарей

1. Высокая эффективность резервного копирования данных

Возможность длительного стабильного электропитания

Он использует герметичную свинцово-кислотную батарею 12В/7,2Ач. В сценариях с низким энергопотреблением ЦП (например, IC693CPU374) он может обеспечить резервное копирование данных в течение 12 месяцев. В сценариях с высоким энергопотреблением он все еще может обеспечить длительную защиту в течение 5 лет с помощью энергосберегающего режима, что на 20% дольше, чем время резервного копирования базовых моделей одной серии (например, IC693ACC302).

Скорость переключения при отключении питания менее 1 мс, что лучше критического времени потери данных в ОЗУ (обычно 5 - 10 мс), обеспечивая бесшовную работу батареи на уровне миллисекунд.

Интеллектуальный механизм управления энергией

Поддерживает двухступенчатую зарядку с постоянным током и постоянным напряжением (постоянный ток 0,72А → постоянное напряжение 13,8В) и автоматически переключается в режим холостой зарядки на 13,2В после полной зарядки, чтобы избежать перезарядки и потери срока службы батареи.

Он оснащен интерфейсом I2C, который может в реальном времени передавать в контроллер напряжение батареи, остаток емкости (точность ±5%) и состояние зарядки, облегчая оповещение о недостатке заряда батареи с помощью програмного обеспечения (например, Proficy Machine Edition) (порог можно настроить, а по умолчанию срабатывание сигнала происходит, когда<20%).

Ii. Environmental adaptability and safety protection performance

Wide temperature and anti-interference design

The operating temperature range is 0℃ to 60℃, and the storage temperature is -40 ℃ to 85℃. It can still operate stably in extreme environments such as metallurgical workshops (high temperature) and cold storage (low temperature).

The anti-vibration performance reaches 5-500Hz (10G acceleration), complies with the mechanical shock standards in industrial sites (such as IEC 60068-2-6), and is suitable for scenarios where equipment starts and stops frequently.

Multiple safety protection systems

Circuit protection: Built-in 1.5A resettable fuse to prevent battery overheating in case of output short circuit; Power interface polarity reverse connection protection to prevent module damage caused by wiring errors;

Temperature compensation: The charging voltage is automatically adjusted according to the ambient temperature (within the range of -20℃ to 60℃). For instance, the charging voltage is 13.8V at 25℃ and increases to 14.2V at 0℃, optimizing battery activity at different temperatures and extending the battery life to 7 years (typical value).

Iii. Interface and Compatibility Advantages

Flexible interface design

It adopts a 4-pin connector (2 pins for power supply + 2 pins for communication), supporting hot-swapping with the controller mainboard (requiring compatibility of the controller hardware). When replacing the battery, there is no need to cut off the power, reducing downtime.

Compatible with the RS-485 communication protocol, it can be connected to the factory SCADA system to achieve remote battery status monitoring (such as voltage and charging cycle counting).

Cross-platform compatibility

It is downward compatible with the older models of the 90-30 series controllers (such as IC693CPU311), upward adapted to the low-power consumption requirements of the PACSystems RX3i series (such as IC695CPU), and supports unified spare parts management for controllers of different generations.

Compatible with the same series of expansion modules (such as IC693ACC350), it can be cascicated to double the backup duration (for example, up to 10 years of backup in high-power scenarios after pairing).

Iv. Performance in Typical Application Scenarios

PLC control of the automotive welding and assembly line

The power grid in the workshop fluctuates occasionally, and it is necessary to protect the welding parameters (such as current and time series) from being lost.

Performance value: RAM data is maintained for 72 hours during power failure (the actual backup time is much longer than the recovery time from sudden power failure), and there is no need to re-debug parameters after restart. A single failure can save 2 hours of production line recovery cost.

Semiconductor wafer processing equipment

The dust-free workshop has high requirements for equipment stability, and the battery needs to have a long service life and be maintenance-free.

Performance value: The sealed lead-acid battery design meets the requirements of a dust-free environment, reducing the replacement frequency by 50% within a 7-year life cycle. Combined with the I2C interface, it provides early warning of battery failure, avoiding wafer scrapping due to data loss (with a single-batch loss of up to 100,000 US dollars).

Wind power pitch control system

Scene requirements: The outdoor environment has a large temperature difference (-30℃ to 50℃), and it needs to be vibration-resistant and operate within a wide temperature range.

Performance value: The operating temperature range of -20℃ to 60℃ covers the temperature difference in wind power scenarios. The anti-vibration design of 5-500Hz ADAPTS to the shaking during wind turbine operation. Temperature compensation charging ensures battery activity in low-temperature environments, avoiding the loss of control of the pitch Angle due to data loss.

V. Suggestions for Maintenance and Performance Optimization

Preventive maintenance

Read the battery voltage through programming software every quarter (normal ≥12.6V). When it is lower than 12V, check the charging circuit.

It is recommended to replace the battery every five years (or when the cumulative charging cycle exceeds 3,000 times) to prevent the capacity from dropping below 70% and affecting the backup duration.

Performance optimization strategy

If it is necessary to extend the backup duration, the energy-saving mode of the controller can be enabled (such as turning off non-essential communication interfaceс). Когда энергопотребление снижается на 30%, продолжительность резервного копирования может быть увеличена с 12 месяцев до 18 месяцев.

Рекомендуется устанавливать вентилятор охлаждения в высокотемпературных средах (> 40°C). При каждом повышении температуры на 10°C срок службы батареи сокращается вдвое. С помощью охлаждения срок службы можно продлить с 5 лет до 7 лет.
