Allen Bradley 1763-L16AWA MicroLogix 1100 Programmable Logic Controller

Product Overview

The Allen Bradley 1763-L16AWA serves as a versatile, compact controller within the MicroLogix 1100 family. This PLC excels in small-scale industrial applications requiring robust AC input processing and localized control. We supply this unit as 100% Brand New and Original, featuring an integrated LCD screen for real-time diagnostics and a built-in Ethernet/IP port for seamless network integration. It provides a cost-effective solution for monitoring 120V AC signals directly without interposing relays.

Technical Specifications

The 1763-L16AWA handles high-voltage AC signals with precision using the following electrical parameters:

Engineering Advantages

• Direct 120V AC Interfacing: The controller accepts standard 120V AC inputs directly. This eliminates the need for 24V DC power supplies and interposing relays when interfacing with standard industrial pushbuttons and limit switches, significantly reducing panel complexity and wiring costs.

• Robust Signal Filtering: Built-in impedance matching (10 kΩ at 60 Hz) filters out electrical noise common in high-voltage AC circuits. This ensures the PLC distinguishes between true logic signals and induced "ghost" voltages from parallel power lines.

• Integrated Visual Diagnostics: The onboard LCD allows maintenance personnel to monitor I/O status and modify controller bits without connecting a PC. This feature accelerates onsite troubleshooting and reduces downtime during machine commissioning.

• High Inrush Tolerance: The input circuitry manages inrush currents up to 250 mA. This protection prevents hardware damage when triggering inputs from capacitive sources or long cable runs that exhibit high initial surge characteristics.

• Deterministic Input Detection: A narrow off-state window (below 20V AC) ensures the PLC maintains a deterministic state. This prevent accidental triggering due to leakage current from solid-state sensors or proximity switches.

FAQs

• What is the significance of the "AWA" suffix in 1763-L16AWA?

  The "AWA" designation indicates that the unit utilizes an AC power supply, 120V AC inputs, and Relay outputs. This configuration suits traditional industrial environments where AC control power is the primary standard.

• Can the 1763-L16AWA operate on both 50 Hz and 60 Hz grids?

  Yes. The controller supports an operating frequency range of 47 to 63 Hz. It automatically adjusts its nominal impedance to provide stable signal detection regardless of the local power grid standard.

• How do I protect the inputs from excessive leakage current?

  Ensure that any connected solid-state sensors do not exceed a 2.5 mA off-state leakage current. If a sensor exceeds this limit, we recommend installing a bleeder resistor to shunt the excess current and maintain reliable "Off" states.

• Is this a genuine, factory-sealed unit?

  Absolutely. We guarantee this 1763-L16AWA is 100% Brand New original hardware. It arrives in the original Allen Bradley factory packaging with all security seals and technical documentation intact.
