Product Description

The Allen-Bradley Central Control Module, a key component in Rockwell Automation’s industrial control systems, serves as the primary processing unit within Programmable Logic Controller (PLC) or Programmable Automation Controller (PAC) architectures. It manages critical tasks such as logic execution, data processing, communication, and system coordination, acting as the central hub in complex automation setups. Commonly integrated into platforms like ControlLogix, CompactLogix, and SLC 500 series, it ensures seamless interaction with I/O modules, HMIs, SCADA systems, and other networked devices.

Product Specifications

The specifications vary depending on the specific module (e.g., ControlLogix 1756 series, CompactLogix 1769 series, or SLC 500 1747 series). Below are general specifications for a typical Allen-Bradley Central Control Module (e.g., 1756-L8x ControlLogix series):

• Processor: High-performance 32-bit or 64-bit processor for fast logic execution.

• Memory:

  • User Memory: Up to 32 MB (non-volatile).

  • I/O Memory: Configurable, typically 1 MB or more.

• Communication Ports:

  • Ethernet/IP, ControlNet, DeviceNet, or serial communication options.

  • Supports multiple protocols (e.g., Modbus, OPC UA).

• Power Supply: 5V DC or 24V DC, depending on the module.

• Operating Temperature: 0°C to 60°C (32°F to 140°F).

• Environmental Rating: IP20, suitable for industrial environments.

• Control Modes: Supports V/f control, sensorless vector control, and closed-loop vector control for motor applications.

• Certifications: UL, CE, and NEMA standards compliance.

For precise specifications, refer to the specific model’s technical documentation (e.g., CENTERLINE 2100 or 2500 MCC documentation).
