- Functional Features:
- 3.6 V/1800 mAh high-capacity lithium manganese dioxide battery provides a long backup time (≥1500 hours at 25°C) for the PLC’s RAM memory and real-time clock, ensuring that the control program, important process data and time information are not lost during long-term power failure of the industrial site.
- Maintenance-free non-rechargeable battery design eliminates the need for regular charging and daily maintenance, reducing the maintenance work of the PLC system, and the long service life (≥4 years at 25°C) reduces the frequency of battery replacement and maintenance cost.
- AEG Modicon 800/850 series PLC dedicated plug-in connector with gold-plated contact pins ensures low contact resistance and stable power supply, the gold-plated pins prevent oxidation and poor contact, and the plug-and-play design simplifies battery installation and replacement.
- Built-in reverse polarity protection and over-discharge protection circuits effectively protect the battery and PLC CPU module from damage caused by incorrect battery installation and excessive discharge, ensuring the electrical safety of the PLC system during battery backup.
- Compact and lightweight structural design (55×25×12mm, 25g) does not occupy additional installation space inside the industrial control cabinet, and the ABS flame-retardant enclosure meets the fire safety requirements of the control cabinet, with high safety performance.
- Wide working temperature range (-25°C to +70°C) ensures stable battery discharge performance in various industrial environments such as low-temperature northern workshops and high-temperature southern production lines, without significant capacity attenuation, with strong environmental adaptability.
- The battery is fully calibrated and matched with AEG Modicon 800/850 series PLC CPU modules, the output voltage and current are perfectly matched with the PLC’s backup power supply requirements, no additional adjustment is needed, and the compatibility and stability are high.
- High energy density lithium manganese dioxide battery has stable discharge voltage, no voltage drop during the backup period, ensuring the normal operation of the PLC’s RAM and RTC, and avoiding data corruption caused by unstable voltage.
- RoHS and CE certification meet the European industrial environmental and electrical safety standards, suitable for industrial control systems with environmental protection requirements, and the battery does not contain harmful substances, which is environmentally friendly and safe.
- The battery is designed with a voltage detection pin, which can send a low-voltage signal to the PLC CPU module when the battery capacity is low, and the PLC can give a fault alarm through the indicator light or HMI, reminding maintenance personnel to replace the battery in time.
- Application Scenarios: Widely used as the dedicated battery backup accessory for AEG Modicon 800/850 series PLC systems in industrial fields such as factory automation, small and medium-sized production line control, building automation, and water treatment on-site control. It is an essential accessory to ensure data retention for the PLC system in occasions such as standalone equipment control, small packaging line control, and municipal small facility control, and is suitable for all industrial occasions that use AEG Modicon 800/850 series PLC and require power failure data and clock retention.
