Features:
- Optimized Mid‑Range Memory Architecture
- Multi‑Protocol Industrial Network Support
- Robust Environmental and Electrical Performance
The Allen‑Bradley 1756‑L55M12/A ControlLogix Controller and Memory Board provides a balanced memory configuration of 750 kbytes for logic and data plus 208 kbytes of dedicated I/O memory. This targeted capacity is ideal for mid‑sized automation tasks such as machine control, batch processing, and material handling, allowing engineers to avoid over‑specifying while still meeting performance requirements.
The Allen‑Bradley 1756‑L55M12/A ControlLogix Controller and Memory Board supports ControlNet, EtherNet/IP, DH+, DeviceNet, and universal remote I/O networks. This flexibility enables seamless integration into both new and existing Rockwell Automation architectures, reducing the need for additional communication adapters and simplifying system design for engineering teams.
The Allen‑Bradley 1756‑L55M12/A ControlLogix Controller and Memory Board operates reliably across a wide temperature range (0…60 °C) and humidity range (5…95% noncondensing), with 30 g operating shock and 2 g vibration tolerance. It draws only 1.23 A at 5.1V DC and dissipates 5.6 W, making it an energy‑efficient choice for industrial control panels without active cooling.
The 1756-L55M12/A Allen-Bradley ControlLogix Processor Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
