Information About 1769-L24ER-QBFC1B

The 1769-L24ER-QBFC1B is part of the CompactLogix 5370 family, designed as a cost-effective controller for small to medium applications requiring high performance in a compact design. It supports up to 32 tasks and 100 programs per task, with 1 MB of memory expandable using the included 1 GB SD card or an optional 2 GB card. The controller features 16 sinking/sourcing 24 VDC digital inputs, 16 sinking digital outputs, 4 high-speed counter inputs, 4 high-speed outputs, 4 universal analog inputs, and 2 analog outputs, providing flexible integration with industrial devices. Communication is supported through two EtherNet/IP ports with Device Level Ring (DLR) topology, one RS-232 port, and one USB port, offering compatibility with DF1, ASCII, DH485, and Ethernet protocols. The unit operates on a 24 VDC power supply, supports expansion with up to 4 Compact I/O modules, and includes protective features such as off-state leakage limits and current handling up to 5 A per channel. With its small form factor and robust capabilities, it is suited for applications like hoisting, cranes, indexing, and packaging systems.

Key Features:

  • Memory: 1 MB embedded memory with expansion support via 1 GB or 2 GB SD cards.
  • Communication: Dual EtherNet/IP ports (DLR supported), one RS-232, and one USB port for programming and networking.
  • Digital I/O: 16 sinking/sourcing 24 VDC digital inputs and 16 sinking 24 VDC digital outputs.
  • High-Speed Functions: Four high-speed counters and four high-speed outputs for motion and precision tasks.
  • Analog Capability: Four universal analog inputs and two analog outputs for process control.
  • Task Handling: Supports 32 tasks and up to 100 programs per task for complex automation.
  • Expansion: Compatible with up to four additional 1769 Compact I/O modules.
  • Power: Operates on 24 VDC with current draw of 1 A at 5 VDC and 0.8 A at 24 VDC.
  • Protocol Support: ASCII, DF1, DH485, and Ethernet/IP for wide communication compatibility.
  • Design: Compact packaged form with LED status indicators and open-type enclosure for easy integration.

The 1769-L24ER-QBFC1B delivers the reliability and precision required for integrated control in space-constrained industrial automation systems.

Question: How do I wire the 1769-L24ER-QBFC1B?
Date Update:29/05/2025
Answer:

Wiring the 1769-L24ER-QBFC1B involves connecting the following:

  • Power Supply: The controller has an integrated 24V DC power supply, so you will need to connect the +24V (positive) and 0V (ground) terminals to your 24V DC power source.
  • I/O Connections: The digital inputs and digital outputs are wired to your field devices (such as sensors, switches, or actuators). Ensure that the input devices are connected to the appropriate input terminals and output devices to the output terminals.
  • Ethernet Communication: The Ethernet port should be connected to your Ethernet network to facilitate communication with other devices (e.g., HMIs, remote I/O, other PLCs).
  • Serial Communication: If using the RS-232/RS-485 serial port, wire it to the appropriate serial devices for communication.

Wiring diagrams and detailed instructions can be found in the product manual, which should be referred to for exact terminal assignments and wiring methods.

Question: What is the maximum number of I/O modules that the 1769-L24ER-QBFC1B can support?
Date Update:29/05/2025
Answer:

The 1769-L24ER-QBFC1B can support up to 8 expansion modules in a system, depending on the I/O requirements of the application. This allows the controller to be customized to meet the needs of the specific control system.
