1756-L83E Allen-Bradley ControlLogix 5580 Processor 10MB

Product Overview

The Allen-Bradley 1756-L83E is a powerful processor module from the ControlLogix 5580 family. It offers 10MB of user memory for logic and data. This controller supports up to 128,000 discrete I/O points. It also handles 4,000 analog I/O channels. The built-in USB port enables easy programming and configuration. An embedded Gigabit Ethernet port supports 10/100/1000 Mbps speeds. This module ships with a 2GB 1784-SD2 secure digital card for nonvolatile storage. It supports full redundancy for critical system availability. The processor can manage up to 32 tasks and 100 programs per task. It uses the Studio 5000 Automation Engineering environment.

Application Scenarios

The 1756-L83E suits complex industrial automation systems. It works well in manufacturing plants and process control environments. Use it for high-speed assembly lines and material handling. It is ideal for oil and gas, water treatment, and power generation. The controller supports remote I/O with Flex I/O and POINT I/O. It communicates with other Allen-Bradley PLCs like PLC-5 and SLC 500. The module fits in ControlLogix chassis for modular expansion. It can implement linear topology through the embedded port. Add communication modules for ControlNet, DeviceNet, or SynchLink. This processor is perfect for applications needing high availability.

Technical Specifications

The 1756-L83E draws 5 milliamps at 1.2 Volts DC. It consumes 1.2 amps at 5.1 Volts DC. Power dissipation is 6.2 Watts. Thermal dissipation equals 21.2 BTU per hour. The module has an isolation voltage of 50 Volts continuous. It weighs 0.25 kg or 0.55 lb. Operating relative humidity ranges from 5 to 95 percent. The USB communication speed is 12 Mbps. The Ethernet port supports 10/100/1000 Mbps auto-negotiation. It supports 100 or 250 Ethernet nodes. Programming languages include relay ladder, structured text, function block, and SFC. The controller supports BOOTP-DHCP for IP configuration.

Installation & Maintenance Guide

Install the 1756-L83E into a ControlLogix chassis slot. Ensure the backplane current is 5 mA at 1.2V and 1.2 mA at 5.1V. Use the USB port for initial programming and configuration. Configure the IP address using BOOTP-DHCP or static settings. For redundancy, install a second processor in the same chassis. Use the 1784-SD2 card for storing programs and firmware. The energy storage module is non-removable and embedded. Perform online edits using the Studio 5000 software. Replace the SD card only when the controller is powered down. Check the display for status and diagnostic messages.
