Information About 1769-L18ERM-BB1B

The 1769-L18ERM-BB1B is part of the CompactLogix 5370 L1 family, designed as a compact yet powerful Programmable Automation Controller (PAC). It integrates 16 DC inputs and 16 DC outputs, while also supporting expansion with up to eight 1734 Point I/O modules for scalable applications. With 512 KB of embedded memory and 1 GB of non-volatile SD storage (1784-SD1 standard, 1784-SD2 optional), it ensures reliable program and data management. Its dual Ethernet ports allow 10/100 Mbps communication in Linear, Star, and Device Level Ring (DLR) topologies, providing robust connectivity to controllers, HMIs, and devices. The onboard USB port supports 12 Mbps transfer rates for programming and diagnostics. Supporting up to 32 tasks with 100 programs per task, the controller is suited for demanding applications, and its integrated motion control can handle up to two axes over Ethernet/IP without additional modules.

Key Features:

  • User Memory: 512 KB embedded memory with 1 GB non-volatile SD storage (replaceable).
  • Embedded I/O: 16 digital 24V DC inputs and 16 digital 24V DC outputs for local control.
  • Expansion Support: Compatible with up to 8 Point I/O modules from the 1734 series.
  • Ethernet Connectivity: Two Ethernet/IP ports supporting Linear, Star, and DLR topologies at 10/100 Mbps.
  • USB Port: One USB 2.0 interface at 12 Mbps for programming and diagnostics.
  • Motion Control: Integrated support for up to 1–2 motion axes over Ethernet/IP.
  • Programming Capacity: Supports up to 32 tasks and 100 programs per task with multiple languages (Ladder, Structured Text, Function Block, SFC).
  • Mounting and Power: DIN rail mounted, powered by 24V DC, with 1A draw at 5V DC.

The 1769-L18ERM-BB1B delivers compact size, integrated motion, and scalable I/O capabilities, making it ideal for mid-range automation systems.
