Product Description

Allen-Bradley 1756-L62 is a ControlLogix 5560 controller that provides 4 MB of user memory for industrial control and automation applications. The unit processes control tasks, manages system I/O, and supports multi-controller configurations within a standard 1756 chassis. It features an integrated RS-232 serial communication port and utilizes a removable lithium battery module for memory retention and clock support during power-down conditions. Nonvolatile memory storage is expanded via an optional CompactFlash card.

Features

  • Built-in RS-232 serial port for programming and serial communication protocols
  • 4 MB user memory capacity for program logic and data storage
  • Supports up to 250 controller connections
  • Nonvolatile memory backup via optional CompactFlash card
  • Removable lithium battery options (1756-BA1 or 1756-BA2) for memory retention during power interruptions
  • Front panel status indicators for diagnostic and operational monitoring
  • Three-position mode switch (RUN, REM, PROG) for system operational control

Applications

  • Industrial process automation and batch control systems
  • Machine control and discrete manufacturing lines
  • Distributed I/O and multi-chassis control configurations
  • Motion control and axis integration
