Technical Specifications

Memory and Processing

The 1756-L82E provides 5 MB of user memory for programs and data. The included 1784-SD2 card adds 2 GB of non-volatile memory for permanent program storage. This controller supports 32 tasks maximum. Each task can contain up to 1000 programs . Event tasks support all triggers for flexible execution. Consequently, this processor handles complex, multi-tasking applications efficiently.

Built-in Communication Ports

The controller features one 1GB Ethernet/IP port supporting 10/100 Mbps and 1 Gbps transmission rates. This port connects to linear plant Ethernet networks and supports up to 80 EtherNet/IP devices . It handles programming, SCADA/HMI communication, and remote I/O. The one USB port serves standard communication purposes (but not industrial communication). The USB port is USB 2.0 compatible.

Optional Communication Adapters

The 1756-L82E supports various optional communication adapters. These include EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink , and third-party process and device networks. This flexibility allows integration with virtually any industrial network.

Redundancy and Motion Control

The controller provides full redundancy support for high-availability applications. Integrated motion control options include SERCOS interface , analog options (encoder input, LDT input, SSI input), and Integrated Motion on the EtherNet/IP network . Therefore, this processor suits advanced motion control and mission-critical systems.

I/O Capacity

The maximum discrete I/O reaches 128,000 points . The maximum analog I/O reaches 4,000 points . These generous capacities eliminate the need for multiple controllers in large installations.

Current Draw and Power

The current draw at 1.2 VDC is 5.0 mA . The current draw at 5.1 VDC is 1.2 mA . Power dissipation measures 6.2 Watts . Thermal dissipation reaches 21.2 BTU per hour . These low power requirements result from the controller's energy-efficient design.

Energy Storage (No Battery Required)

The 1756-L82E does not require batteries to retain RAM data. Instead, it uses an environmentally friendly energy storage module composed of capacitors . Please note that this energy storage module cannot be replaced or removed from the controller . This eliminates battery maintenance and disposal concerns.

Isolation Voltage

The isolation voltage rating is 50 Volts continuous . Basic insulation testing includes 1000V AC for 60 seconds between USB-to-Ethernet, USB-to-backplane, and Ethernet-to-backplane. This robust isolation protects the controller from field wiring faults.

Temperature and Environmental Ratings

The operating temperature range spans 0 to 60°C (32 to 140°F) . Non-operating temperature ranges from -40 to 85°C (-40 to 185°F) . Relative humidity tolerance reaches 5 to 95% non-condensing .

Shock and Vibration Tolerance

Operating shock tolerance reaches 30G . Operating vibration tolerance is 2G at 10-500 Hz . This rugged construction suits demanding industrial environments.

Chassis Compatibility

The 1756-L82E is compatible with standard ControlLogix chassis. These include 1756-A4, 1756-A4K, 1756-A7, 1756-A7K, 1756-A10, 1756-A10K, 1756-A13, 1756-A13K, 1756-A17, and 1756-A17K Series B and Series C .

Display

The controller features a 4-character alpha/numeric display for local status indication. Use this display for quick diagnostics without programming software.

Installation Guide

Follow these steps to install your 1756-L82E correctly.

1. Power Down the Chassis: Disconnect power from the ControlLogix chassis completely. This prevents electrical damage during installation.

2. Select a Slot: Choose an available slot in the ControlLogix chassis. The 1756-L82E occupies one slot.

3. Insert the Module: Align the 1756-L82E with the slot guides. Push firmly until the module seats into the backplane connector.

4. Secure the Module: Tighten the retaining screws at the top and bottom. This secures the processor module in place.

5. Insert the Memory Card: Install the included 1784-SD2 2GB non-volatile memory card into the controller's card slot.

6. Connect Ethernet: Attach your Ethernet network cable to the 1GB Ethernet/IP port . Use standard CAT5e or CAT6 cabling.

7. Connect USB (Optional): Attach a USB cable to the USB port for programming or data transfer (non-industrial use only).

8. Apply Power: Restore power to the ControlLogix chassis. Verify that the processor powers up and the display shows normal status.

9. Download User Program: Transfer your control program to the 5 MB user memory. Use Studio 5000 programming software.

10. Verify Operation: Check the alpha/numeric display for diagnostic codes. Confirm communication with I/O and other network devices.
