Features:
- Provides 4 MB of user memory and 478 KB of I/O memory to accommodate extensive ControlLogix programs.
- Supports optional 1784-CF128 nonvolatile memory, enabling battery-free operation and preservation of saved tag data.
- Works with several ControlLogix chassis sizes and supports both standard and redundant power supply arrangements.
Allen-Bradley 1756-L62 is widely used in manufacturing, process control, and large automation systems where a high number of I/O points must be managed reliably. The controller can support up to 128,000 total I/O points, making it suitable for applications that require significant expansion capability. Its open-style construction allows installation inside industrial control cabinets. Compatibility with redundant power supplies also helps improve system availability.
The architecture of Allen-Bradley 1756-L62 combines memory capacity with communication flexibility. The controller contains 4 MB of user memory and 478 KB dedicated to I/O functions. RS-232 connectivity is available through 1756-CP3 or 1747-CP3 cables, while electrical isolation of the serial interface reaches 30 V continuous. Optional CompactFlash storage can provide nonvolatile memory functionality and reduce dependence on batteries.
Allen-Bradley 1756-L62 is intended for demanding environments where temperature, humidity, and vibration resistance are important considerations. The unit operates between 0 and 60 °C and tolerates noncondensing humidity levels up to 95%. Storage capability extends down to -40 °C and up to 85 °C. Documentation also describes SFC reset behavior in Programmatic Reset and Automatic Reset modes, allowing final scan execution and shutdown processing when configured accordingly.
The 1756-L62 Allen-Bradley ControlLogix 4 MB Memory Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
