Key Functional Features

• Extended Memory Backup Time: Provides substantially longer data retention compared to standard internal PLC batteries. For most Series 90-30 CPUs (models 311-364) and all existing IC697 CPUs, the backup time extends up to 75 months. For the IC693 CPU374, it extends up to 15 months.

• High Capacity and Reliability: The 15 Ah lithium battery offers a massive power reserve and a low self-discharge rate. Its shelf life of seven to ten years ensures the module is viable for long-term deployment even before installation.

• Integrated Safety Protections: A 1-Amp sealed fuse is integrated into the battery pack to protect against short circuits or severe overloads, safeguarding the auxiliary battery and the connected PLC’s memory circuit.

• Durable and Safe Enclosure: The entire unit is housed in a black, flame-retardant ABS plastic case designed to withstand mechanical vibrations and the electromagnetic interference common in industrial environments.

• User Alert via PLC: As the battery nears its depletion point, the BATT LED indicator on the host PLC’s CPU module illuminates, providing a clear signal that a replacement is required.

Application Scenarios

• Power Generation and Energy Sector: Protects PLC Memory in power generation facilities, substations, and renewable energy sites where control logic for generator sets and power distribution must be retained through grid faults and extended blackouts.

• Oil and Gas Industry: Preserves critical control programs and data in remote pipeline monitoring, wellhead control, and refinery process systems where power outages can be frequent or prolonged, and on-site maintenance is challenging.

• Water and Wastewater Treatment: Maintains PLC data integrity for chemical dosing schedules, pump control logic, and Supervisory Control and Data Acquisition (SCADA) configurations during power interruptions, preventing operational failures and regulatory non-compliance.

• Industrial and Discrete Manufacturing: Ensures the retention of user programs and configuration data for automated production lines, robotic work cells, and machine control systems, preventing costly downtime and reprogramming after power loss.

• Transportation and Other Critical Infrastructure: Provides essential backup power in applications such as transportation control systems and aerospace support equipment, where data loss due to power failure can have significant operational or safety implications.
