Product Overview

1756-L85EP is an Allen-Bradley ControlLogix 5580E process controller for chassis-based process and automation applications.

Rockwell Automation specifies 40 MB of user memory, a preinstalled 4 GB 1784-SD4 Secure Digital card, an embedded 1 Gb EtherNet/IP port, a USB local programming port and support for up to 300 EtherNet/IP devices.

The controller occupies one slot in a compatible 1756 chassis, is conformal coated and uses an embedded non-removable energy storage module. Rockwell Automation lists it as End of Life with planned discontinuation on December 31, 2026 and 1756-L85EPXT as the direct replacement.

Applications & Features

Process-optimized controller

The 1756-L85EP is optimized for process applications and is conformal coated for protection in corrosive industrial atmospheres.

40 MB application memory

The controller provides 40 MB of user memory for large process logic, data and control strategies.

Embedded high-speed networking

The integrated 1 Gb EtherNet/IP port supports up to 300 devices without a separate Ethernet module.

Preinstalled storage

A 4 GB 1784-SD4 Secure Digital card ships installed for nonvolatile project and tag-data storage.

Communications

EtherNet/IP	One embedded 1 Gb Ethernet port supporting up to 300 EtherNet/IP devices.
USB	USB local programming port for temporary programming and configuration only.
ControlLogix backplane	The controller receives chassis power and exchanges data through the 1756 backplane.
Secure Digital card	Front-accessible card slot with a preinstalled 4 GB 1784-SD4 card.
Industrial cabling	Use Ethernet cabling and installation practices compliant with IEC 61918 and IEC 61784-5-2.

Installation

01 - Verify the complete catalog number

Match 1756-L85EP on the quotation, controller label, packaging and Rockwell Automation product record.

02 - Confirm controller capacity

Verify 40 MB user memory and the 300-device EtherNet/IP limit against the validated process project.

03 - Select the chassis

Use a compatible standard Series B or C, XT Series C or ZXT chassis and apply its corresponding temperature limit.

04 - Install the controller

De-energize the chassis, align the circuit board with the guides and seat the controller fully in one compatible slot.

05 - Protect unused ports

Keep the specified protection plugs or covers installed in unused ports to maintain the published corrosive-atmosphere rating.

Environment

Operating temperature

-25 to +70 degrees C with a compatible XT Series C or ZXT chassis; -25 to +60 degrees C with a standard Series C chassis; -25 to +50 degrees C with a standard Series B chassis.

Storage temperature

-40 to +85 degrees C.

Relative humidity

5 to 95 percent, noncondensing.

Corrosive atmosphere

Conformal coated; G3 and CX severity under the stated port-protection conditions.

Hazardous locations

Class I, Division 2 and Zone 2 approvals apply when marked and installed according to official instructions.

Protection

Open-style equipment; install in an enclosure appropriate for the application.

FAQ

Q1. How can the exact quoted 1756-L85EP be verified?

Match the full 1756-L85EP catalog number on the quotation, controller label and packaging. Confirm 40 MB user memory, process-controller designation, embedded Ethernet port, USB port and four-character display.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the complete label, serial and series markings, Ethernet and USB ports, SD-card area, display, mode switch, backplane connector and housing. Check for connector wear, repaired plastic or changed labels.

Q3. How should supplier legality and reliability be checked?

Verify the supplier legal entity, registered address, payment beneficiary, invoice details and traceable sales contact. The written offer must identify Allen-Bradley, 1756-L85EP, condition and quantity.

Q4. Which specifications must engineering confirm before purchase?

Confirm 40 MB user memory, 300-device EtherNet/IP capacity, embedded 1 Gb Ethernet, USB commissioning, 4 GB SD storage, chassis series, temperature range, firmware and process redundancy requirements.

Q5. What physical evidence should be requested before payment?

Ask for one date-marked photo set showing the complete 1756-L85EP label, serial and series markings, Ethernet and USB ports, SD-card slot, four-character display, backplane connector, port-protection plugs, seals and packaging.

Q6. Can 1756-L85E or 1756-L85EPXT replace 1756-L85EP?

Not automatically. 1756-L85E is a standard controller, while 1756-L85EPXT is the listed process-controller replacement with different environmental positioning. Confirm process features, chassis, firmware, coating and approvals before substitution.
