As part of the MicroLogix 1100 series, this controller bridges the gap between micro-PLCs and full-scale industrial processors. It features integrated Ethernet/IP for seamless networking and an onboard LCD for real-time diagnostics. We supply this unit as 100% brand new and original, ensuring the highest level of execution for your machine-level control applications.

Part Number Breakdown

The 1763-L16BBB follows the Allen-Bradley hardware identification logic for the MicroLogix family:

Technical Specifications

The 1763-L16BBB delivers precise control through the following technical parameters:

• Input Power: 24V DC (Operational range 20.4V to 26.4V DC)

• Digital Inputs: 10 total (including 4 High-Speed 40kHz inputs)

• Digital Outputs: 6 FET (Source) 24V DC outputs

• Analog Inputs: 2 channels (0–10V DC, 10-bit resolution)

• Communication: 1x Ethernet/IP Port, 1x RS-232/RS-485 Combo Port

• Memory: 8 KB (4 KB User Program / 4 KB User Data)

• Off-State Voltage Range: 0 to 5V DC

• Off-State Leakage Current: 1.5 mA maximum

• Nominal Impedance: 3.1 kΩ

• Weight: 0.9 kg

• Dimensions: 11 cm x 9 cm x 8.7 cm

Engineering Advantages

• Built-in Visual Diagnostics: The integrated LCD screen allows operators to monitor I/O status, modify bit values, and check system errors directly at the machine. This eliminates the need to connect a laptop for simple troubleshooting in tight field conditions.

• High-Speed Counting Capability: The unit features four high-speed inputs (up to 40kHz). This functionality supports direct connection to incremental encoders, enabling precise positioning and high-speed counting without requiring expensive specialized expansion modules.

• Integrated Ethernet Networking: The native Ethernet/IP port facilitates easy integration into modern industrial networks. It supports peer-to-peer messaging and SCADA connectivity, allowing remote monitoring and program modifications over standard office networks.

• Compact Footprint: With dimensions of only 11 cm x 9 cm x 8.7 cm, the 1763-L16BBB fits into extremely shallow enclosures. This solves the challenge of adding advanced control logic to pre-existing machine panels with limited rail space.

FAQs

• Can the 1763-L16BBB expand its I/O capacity?

  Yes. You can expand the controller using up to four 1762 MicroLogix Expansion I/O modules. This allows you to increase digital or analog channel counts as your system requirements grow.

• How do I configure the Ethernet port?

  You can set the IP address directly through the onboard LCD keypad and menu or via the BOOTP/DHCP utility in your programming software (RSLogix 500).

• What is the difference between the 1763-L16BBB and the 1763-L16BWA?

  The L16BBB model utilizes 24V DC power and DC FET outputs, whereas the L16BWA model requires 120/240V AC power and utilizes Relay outputs. Ensure your power rail and load types match the "BBB" DC-source specification.

• Does this PLC support online editing?

  Yes. The MicroLogix 1100 series supports online editing, allowing you to modify your logic while the machine is running. This feature significantly reduces downtime during process tuning and commissioning.
