1763-L16BWA | Allen Bradley | MicroLogix 1100 Programmable Logic Controller

Product Overview

The Allen Bradley 1763-L16BWA functions as a compact yet powerful controller within the MicroLogix 1100 family. This PLC bridges the gap between basic micro-controllers and high-end modular systems by offering integrated 10/100 Mbps EtherNet/IP™ connectivity for peer-to-peer messaging. It features a versatile I/O count, including 10 digital inputs, 2 embedded non-isolated analog inputs, and 6 relay outputs. Designed for applications requiring high-speed counting and flexible communication, the 1763-L16BWA serves as a cornerstone for small-scale industrial machinery, building automation, and remote monitoring stations.

Technical Specifications

Engineering Advantages

• Integrated High-Speed Capability: The 1763-L16BWA supports operating frequencies up to 20 kHz. This allows the controller to interface directly with high-speed encoders and flow meters, executing precise pulse-counting tasks without requiring expensive dedicated counter modules.

• Embedded Analog Functionality: Two integrated 0-10V DC analog inputs enable the direct monitoring of temperature sensors, pressure transmitters, or potentiometers. This onboard capability saves significant DIN rail space and reduces total hardware expenditure by eliminating the need for separate analog expansion cards.

• Versatile Relay Outputs: The six relay outputs handle diverse load types, allowing the controller to switch both AC and DC field devices simultaneously. This flexibility simplifies circuit design when controlling a mix of solenoids, contactors, and pilot lights.

• Robust Signal Integrity: A 3.1 kΩ nominal input impedance combined with a strict 1.5 mA off-state leakage threshold ensures the controller rejects electrical noise and phantom signals. This high-threshold design prevents false triggering in environments with significant electromagnetic interference (EMI).

• Direct EtherNet/IP Messaging: The built-in Ethernet port facilitates seamless integration into plant-wide networks. It supports online editing, which allows engineers to modify code and tune parameters without stopping the machine, drastically reducing commissioning time and production downtime.

FAQs

• Is the 1763-L16BWA supplied as 100% Brand New?

  Yes. We provide this controller as 100% Brand New in original factory-sealed packaging. This guarantees the latest manufacturing standards and ensures the internal real-time clock and memory backup remain at full capacity.

• Does this model require a separate power supply for the processor?

  The "BWA" suffix indicates that this model utilizes 120/240V AC line power for the controller itself, while providing a 24V DC sensor power source. This eliminates the need for an external bulk DC power supply for the base unit.

• Can I expand the I/O capacity beyond the built-in 18 points?

  Yes. The 1763-L16BWA supports up to four 1762 MicroLogix Expansion I/O modules. This allows you to scale the system as your automation requirements grow, supporting additional digital, analog, or specialty temperature inputs.

• How do I configure the 2 embedded analog inputs?

  You access the analog data through the controller's input image table. These 0-10V DC inputs provide 10-bit resolution, ideal for general-purpose monitoring. Note that these inputs are non-isolated, so ensure proper grounding of your field transmitters to avoid ground loops.
