Allen-Bradley 1756-L60M03SE ControlLogix Programable Controller Module

Description

The Allen-Bradley 1756-L60M03SE is a two-slot combination controller module belonging to the ControlLogix 5560 product family. The 1756-L60M03SE features 750 KB of integrated data and logic memory alongside an I/O memory capacity of 478 KB. Designed with an integrated three-axis SERCOS interface, the 1756-L60M03SE delivers performance similar to a ControlLogix 5563 controller while providing direct motion control for up to three SERCOS interface drives.

The 1756-L60M03SE includes one integrated RS-232 serial communication port and supports diverse industrial networks via optional ControlLogix communication modules, including EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, and SynchLink. Operating under IEC 61131-3 compliance, the 1756-L60M03SE supports standard programming languages including Relay Ladder, Structured Text, Function Block Diagram, and Sequential Function Chart (SFC).

Features

• Two-slot ControlLogix combination controller with integrated 3-axis SERCOS interface
• 750 KB integral data and logic memory with 478 KB I/O memory
• Nonvolatile memory storage via optional 1784-CF64 Industrial CompactFlash card
• Support for extended battery backup using the 1756-BATM battery module
• Multi-language programming support compliant with IEC 61131-3 (Relay Ladder, Structured Text, Function Block Diagram, SFC)
• Support for up to 250 controller connections
• Integrated motion support for Encoder, LDT, and SSI inputs
• Motion control expansion capability via optional chassis modules (e.g., 1756-M03SE, 1756-HYD02, 1756-M02AE, 1756-M02AS)

Applications

• Multi-axis SERCOS servo motion control systems
• Distributed process and discrete automation networks
• Complex packaging, material handling, and assembly machinery
• Stand-alone or multi-rack distributed PAC architecture

Technical Specifications

Installation Guidelines

• Module Placement: Ensure the two-slot controller is securely seated into adjacent backplane slots of a compatible 1756 ControlLogix chassis before applying power.
• SERCOS Ring Topology: When connecting SERCOS interface drives to the optical port, ensure each axis on a SERCOS ring uses a unique node number. Ensure each additional SERCOS module in the chassis maintains its own independent ring.
• DH-485 Network Precaution: Disconnect the controller from any DH-485 network prior to performing firmware updates to prevent network communication failure.
• Grounding & Shielding: Follow standard ControlLogix system guidelines for chassis grounding and fiber-optic media handling to mitigate EMI/RFI interference.
