Import Allen Bradley Controllogix 1756 Controller — Buy in Bulk from Supplier in China

The Allen Bradley ControlLogix 1756 Controller is a modular programmable logic controller from Rockwell Automation, distributed by Autowell International Limited from Shenzhen, China. The series spans standard ControlLogix units (1756-L61 through 1756-L75), GuardLogix safety controllers (1756-L61S through 1756-L73SXT), Armor variants for harsh environments (1756-L72EROM, 1756-L73EROM), and redundancy modules (1756-RM2, 1756-RM2XT). Processor options range from legacy L6x controllers with integrated serial ports to L7x and L8x generations with embedded EtherNet/IP and expanded motion control capabilities. Memory configurations vary by catalog number, with L7xK and L8xEK variants offering expanded on-board memory for complex process applications.

ControlLogix controllers use the 1756 chassis backplane architecture and communicate via ControlNet, DeviceNet, or EtherNet/IP networks depending on the installed communication module. The L7x and L8x series processors support integrated motion on EtherNet/IP using C_REM instruction sets, while GuardLogix variants incorporate dual-processor architecture for SIL 3 / PLe safety applications. Armor controllers carry IP67-rated enclosures for cabinet-free installation in washdown or vibration-prone environments. Redundancy modules (1756-RM2) enable bumpless switchover between paired chassis for critical process continuity. Typical industrial operating temperature for standard units ranges from 0 to 60 degrees Celsius, with XT (extended temperature) variants rated for harsher thermal profiles.

These controllers serve discrete manufacturing, continuous process, and hybrid applications across automotive assembly, food and beverage packaging, oil and gas processing, and water treatment sectors. Autowell International Limited positions itself as a Rockwell Automation agent covering Hong Kong and mainland China, offering the full PLC portfolio including SLC 500, CompactLogix, and associated HMI, inverter, and CNC lines. Buyers should verify firmware revision compatibility with existing 1756 I/O modules, confirm whether GuardLogix safety task licensing is included, and establish warranty coverage terms for units shipped from Shenzhen. Project-based volume pricing and local technical support availability should be discussed directly with the supplier.

Autowell International Limited operates from Xixiang Street in Baoan District, Shenzhen, Guangdong Province, China, with additional presence referenced in Hong Kong. The supplier holds harbor-tier platform status and maintains a zero percent response rate with zero average response hours recorded, indicating minimal buyer engagement through the platform messaging system. The company explicitly identifies as a Rockwell Automation agent for Hong Kong and China, specialising in the full Allen Bradley PLC portfolio rather than manufacturing its own hardware.

The supplier's listed scope covers ControlLogix, CompactLogix, SLC 500, and legacy PLC-5 systems, plus associated HMI panels, variable frequency drives, and CNC interfaces. The source description emphasises project-based cost savings for bulk purchasing, though no verified client references, annual turnover, warehouse capacity, or after-sales service infrastructure details are provided. Buyers should independently verify Autowell's current Rockwell Automation distribution authorisation status, as agent relationships can change, and confirm whether technical support extends beyond supply to include commissioning assistance or spare parts holding.
