Functions

Safety processing

The controller provides dedicated standard and safety memory while supporting the configured EtherNet/IP device and OPC UA node limits for this exact catalog number.

Programming capacity

Rockwell Automation specifies 32 tasks and up to 1000 programs per task, with RLL, structured text, function block and sequential function chart languages.

I/O scale

The platform supports up to 128,000 digital I/O, 4,000 analog I/O and 128,000 total I/O.

Integrated motion

The ControlLogix 5590 platform supports integrated motion and high-performance Logix control applications.

Interfaces

Embedded Ethernet

Two 10/100/1000 Mbps Ethernet ports support controller networking and EtherNet/IP communications.

USB Type-C

USB 2.0 full-speed communication at 12 Mbps is provided for local programming, configuration, firmware updates and online edits.

Removable storage

An 8 GB 1784-MSD8 microSD card is preinstalled for nonvolatile storage.

Network capacity

The exact 1756-L902TS limit is 30 EtherNet/IP devices and 300 OPC UA nodes.

Installation

Chassis placement

Install the one-slot controller in any compatible Series B or Series C ControlLogix chassis slot and follow official grounding and installation instructions.

Electrical loading

Allow for 5.0 mA at 1.2 V DC and 1.20 A at 5.1 V DC, with 6.2 W power dissipation and 21.2 BTU/hr thermal dissipation.

Enclosure

Use a suitable windowless NEMA 1 or equivalent metal enclosure because the controller is open-style equipment.

Mechanical reference

Use the official Rockwell Automation 2D drawing for 1756-L902TS when confirming dimensions, spacing and enclosure clearances.

Safety Features

Safety integrity

The primary controller can support up to SIL 2/PLd; SIL 3/PLe requires the specified safety partner and approved architecture.

Safety memory

The exact 1756-L902TS catalog number provides 2 MB safety memory in addition to 2 MB standard memory.

Environmental limits

Observe 0 to 60 deg C in Series C chassis and 0 to 50 deg C in Series B chassis for SIL 2 and SIL 3 applications.

Certification scope

Verify required functional-safety certificates, firmware revisions and project standards against the current Rockwell Automation certificate set before commissioning.

FAQ

Frequently Asked Questions

Q1. How can I verify that a quotation is for the exact 1756-L902TS catalog number?

Match 1756-L902TS on the quotation, factory carton and controller nameplate. The correct model has 2 MB standard memory, 2 MB safety memory, 30 EtherNet/IP device capacity and 300 OPC UA nodes.

Q2. How can I distinguish a new 1756-L902TS from used or refurbished equipment?

Request current photos of sealed packaging, catalog and serial labels, chassis connector condition, both Ethernet ports, USB Type-C port, display and the installed 1784-MSD8 card. Opened seals, mounting marks or worn connectors can indicate prior use.

Q3. How should a buyer check whether a 1756-L902TS supplier is legitimate?

Verify the legal company name, business registration, bank beneficiary and traceable contact details. Require the supplier to cite the official 1756-L902TS cut sheet and publication 1756-TD001W-EN-P pages 4-7.

Q4. Which specifications should an engineer confirm before ordering 1756-L902TS?

Confirm 2 MB standard memory, 2 MB safety memory, 30 EtherNet/IP devices, 300 OPC UA nodes, firmware and Studio 5000 compatibility, chassis series, current draw, operating temperature and required safety integrity level.

Q5. What physical evidence should be requested before payment for 1756-L902TS?

Request dated photos or video showing the exact nameplate, serial number, factory carton, status display, both Ethernet ports, USB Type-C port, backplane connector and preinstalled 8 GB microSD card. Evidence must correspond to the quoted unit.

Q6. Can another ControlLogix 5590 suffix replace 1756-L902TS?

Not automatically. Suffixes can change memory, device and OPC UA node capacity, coating, environmental rating and safety architecture. Any alternative requires a full engineering comparison and written approval.
