• Integrated dual-processor architecture providing standard control alongside dedicated safety memory execution.
• Support for up to 100 motion axes for complex motion control applications.
• RS-232 serial port for local programming, diagnostic monitoring, and ASCII communication.
• Expandable non-volatile memory via removable CompactFlash card options.
• Direct integration into ControlLogix 1756 chassis backplanes.

Features

• Incorporates 8 MB standard application memory and 4 MB dedicated safety memory.
• Provides 1 RS-232 local programming port.
• Supports up to 100 coordinated motion axes.
• Utilizes CompactFlash cards for non-volatile program and data storage options.
• Uses a replaceable 1756-BA2 energy storage battery module.

Applications

• High-integrity safety shutdown systems (SIS)
• Factory automation and interlocking safety gates
• Multi-axis coordinated servo motion control
• Automotive assembly lines and robot cell safety monitoring

Installation Guidelines

• Ensure proper grounding of the 1756 ControlLogix chassis backplane prior to controller insertion.
• Handle the module using proper ESD protection to prevent damage to internal solid-state components.
• Insert the controller firmly into any open chassis slot until the module locking tabs engage securely.
• Install the 1756-BA2 lithium battery module before applying system power to ensure memory retention.
• Maintain adequate clearance above and below the chassis for natural convection cooling and airflow.
