Exact Catalog Configuration

1756-L61 is the Series B ControlLogix 5560 2 MB memory controller identified on the official Rockwell Automation product page.

Lifecycle Status

Rockwell Automation lists this catalog number as discontinued as of June 1, 2017 and identifies a functional replacement category. Procurement must therefore verify exact catalog identity and condition.

Chassis-Based Architecture

The controller is used in the ControlLogix 1756 chassis platform. Network and field interfaces depend on the communication and I/O modules installed in the chassis.

Procurement Evidence

Request clear nameplate, Series B, serial-number, connector and packaging photographs for 1756-L61. Require the supplier to state New, Used or Refurbished condition in writing.

Controller Scope

Controller Memory

1756-L61 provides 2 MB controller memory in the Series B ControlLogix 5560 platform. Memory capacity is the key differentiator that must match the original project.

Lifecycle Planning

The official product page lists the controller as discontinued from June 1, 2017. Confirm the exact legacy requirement before evaluating a functional replacement.

System Architecture

The controller occupies the processor role in a ControlLogix 1756 chassis. Communication, I/O and motion functions depend on separately selected chassis modules.

Interfaces

Chassis Backplane

The controller communicates with installed 1756 modules through the ControlLogix chassis backplane. Verify chassis slot allocation and module compatibility for the existing project.

Network Interfaces

EtherNet/IP, ControlNet, DeviceNet and other communications are provided through separately selected compatible 1756 interface modules, not by changing the processor catalog number.

Programming Connection

Confirm the controller revision, project software compatibility and the approved programming cable or communication path before commissioning.

Installation

Catalog and Series Check

Match the full catalog number 1756-L61 and Series B before installation. Memory size and controller revision must match the intended ControlLogix project.

Chassis and Power

Confirm the target 1756 chassis, power supply capacity, slot assignment and surrounding module compatibility before inserting the controller.

Legacy Project Validation

Back up the project and verify firmware, programming software, network modules and replacement strategy before removing an installed legacy controller.

Environment

Published Physical Data

Rockwell Automation publishes dimensions of 222 × 179.07 × 54.1 mm and a weight of 0.494 kg for 1756-L61. Use these values when checking enclosure and shipping documentation.

Lifecycle

The official product page lists this catalog number as Discontinued from June 1, 2017. Condition and exact legacy compatibility require special procurement review.

Certification and Destination

Use only the current certification records shown on the official product page and technical data publication. Confirm the approvals required for the destination project before purchase.

FAQ

Q1. How can a buyer verify that the quotation is for the exact 1756-L61 catalog number?

Require the full catalog number and compare the nameplate with the official Series B ControlLogix 5560 record, 2 MB memory specification and lifecycle information.

Q2. How can New, Used and Refurbished condition be distinguished for 1756-L61?

Request dated photographs of packaging, the catalog/series/serial label, chassis connector, keyswitch and housing. The supplier must disclose mounting wear, repair labels or replacement components.

Q3. How should a supplier be checked before ordering 1756-L61?

Verify the legal company name, registration, address, bank beneficiary and written condition/warranty statement. For a discontinued controller, request catalog-specific stock evidence before payment.

Q4. Which specifications must engineering confirm before purchase?

Confirm 2 MB memory, Series B, firmware revision, project software, chassis slot, power supply, communication modules and legacy replacement plan.

Q5. What physical evidence should be requested before payment?

Request clear photographs of all sides, the catalog/series/serial label, connector area, keyswitch and packaging. Ask for a dated power-up or test record only when the supplier claims the unit was tested.

Q6. Can a similar controller or different suffix replace 1756-L61?

Not automatically. Memory capacity, firmware, chassis compatibility and project conversion requirements can differ. Use the exact catalog unless the responsible engineer approves a documented functional replacement.
