1. Rendimiento eficiente de copia de seguridad de datos

Capacidad de suministro de energía estable a largo plazo

Adopta una batería de plomo-ácido sellada de 12V/7.2Ah. En escenarios de CPU de bajo consumo (como IC693CPU374), puede soportar la copia de seguridad de datos durante 12 meses. En escenarios de alto consumo, todavía puede lograr una protección a largo plazo de 5 a?os a través del modo de ahorro de energía, lo que es un 20% más largo que el tiempo de copia de seguridad de los modelos básicos de la misma serie (como IC693ACC302).

La velocidad de conmutación en caso de corte de energía es inferior a 1ms, lo que es superior al tiempo crítico de pérdida de datos de la RAM (generalmente 5 - 10ms), garantizando una vida útil de batería sin interrupciones a nivel de milisegundos.

Mecanismo de gestión de energía inteligente

Soporta la carga en dos etapas de corriente constante y voltaje constante (corriente constante de 0.72A → voltaje constante de 13.8V), y se cambia automáticamente al modo de carga flotante de 13.2V después de la carga completa para evitar la sobrecarga y la pérdida de la vida útil de la batería.

Está equipado con una interfaz I2C, que puede enviar de forma real-time la tensión de la batería, la capacidad restante (precisión ±5%) y el estado de carga al controlador, lo que facilita la alerta temprana de la batería con poca carga a través del software de programación (como Proficy Machine Edition) (el umbral se puede personalizar, y la alarma predeterminada es cuando<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 interfaces). Cuando el consumo de energía se reduce en un 30%, la duración de la copia de seguridad se puede aumentar de 12 meses a 18 meses.

Se recomienda instalar un ventilador de refrigeración en entornos de alta temperatura (> 40℃). Por cada aumento de 10℃, la vida útil de la batería se reduce a la mitad. A través de la refrigeración, la vida útil se puede extender de 5 a?os a 7 a?os.
