Information About 1769-L33ER

The 1769-L33ER CompactLogix 5370 controller by Allen-Bradley is a compact Logix controller. The 1769-L33ER can communicate with the controller or other devices through the Ethernet port. This controller has built-in user memory of 2 MB. It is packaged with an optional non-volatile memory card which amounts to 1GB, thay may be expanded up to 2GB. The 1769-L33ER can support Sixteen (16) I/O modules with a maximum of Three (3) I/O banks connected by appropriate expansion cables.

The 1769-L33ER has a draw current of 5 Volts DC at 560 mA across 4 power supply modules and has a maximum power dissipation of 4.5 Watts. It has a 500 mA @ 5VDC backplane current draw and a maximum bus insulation 30 Volts. The 1769-L33ER can be mounted using either a DIN rail or panel mounting.

The 1769-L3ER CompactLogix controller has an average weight of 0.31 kilograms (0.68 pounds) and comes with an open-style enclosure. It is an Electronic device with an operating temperature range of a 0 to 60 degree Celsius (32 to 140 degree Fahrenheit) and a -40 to 85 degree Celsius (-40 to 185 degree Celsius) storage temperature, with a maximum relative noncondensing humidity range between 0 to 95%. This unit can be used with several different power supplies, such as the 1769-PA4, the 1769-PA2, and the 1769-PB4.

The Allen-Bradley 1769-L33ER belongs to the CompactLogix 5370 L3 controllers. This product series are 1769 CompactLogix controllers that is Allen-Bradley’s modular and cost-effective solution for medium sized applications. This controller features Logix platform capabilities and supports a degree of expansion far greater than the micro automation controller’s capabilities. The 1769-L33ER supports up to Sixteen (16) Local I/O module installation with the ability to use up to Three (3) I/O expansion banks. It is also provided with an embedded dual ethernet that act as an embedded switch and supports 10/100 mbps data rate with auto-negotiation capabilities.

The Ethernet communication port serves as the controller’s interface to the communication highway. It uses Ethernet I/P protocol to send and receive data to and from partner devices. Up to 32 Ethernet nodes may be connected at a time. Typical devices that may be communicated with this port are Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA), Distributed Control Systsems (DCS), gateways, converters, databases, enterprise tools and other products.

A single USB interface is also provided which may serve as the fallback communication protocol. This USB interface is typically used for primary configurations and troubleshooting.

This controller supports DIN rail or panel mounting which is similar to MicroLogix systems. It does not require an electronic rack or chassis which advanced control systems for large application such as ControlLogix require. The 1769-L33ER support installation of 1769-SDN or DeviceNet scanner module. With the use of DeviceNet interface, Compact I/O modules that resides in the DeviceNet link may be communicated with.

Frequently Asked Questions about 1769-L33ER
Question: How much power does the 1769-L33ER dissipate during operation?
Date Update:29/05/2025
Answer:

The 1769-L33ER controller has a maximum power dissipation of 4.5 Watts. It draws a current of 560 mA at 5 Volts DC and is designed to work with several power supply modules like the 1769-PA2, 1769-PA4, or 1769-PB4. This low power dissipation contributes to reduced heat generation and efficient operation in compact control enclosures. Proper ventilation or spacing is still recommended for reliable long-term performance.

Question: What is the maximum number of programs and tasks supported by this controller?
Date Update:29/05/2025
Answer:

The 1769-L33ER can manage up to 32 tasks, either periodic or continuous, with each task supporting up to 100 programs. This provides advanced scheduling and multitasking capabilities. It is well-suited for systems that require modular code organization or parallel process control. Such flexibility enhances programming efficiency and performance.

Question: What is the size and weight of the controller?
Date Update:29/05/2025
Answer:

The 1769-L33ER measures approximately 8 x 8 x 5 inches and weighs 0.68 pounds (0.31 kg). This compact size makes it suitable for use in tight control cabinet spaces. Despite its small footprint, it delivers significant processing power. The lightweight design also simplifies handling during installation.

Question: How many I/O modules can be connected to the 1769-L33ER controller?
Date Update:29/05/2025
Answer:

The 1769-L33ER supports up to 16 local expansion I/O modules directly connected to the controller. These can be arranged into a maximum of 3 separate I/O banks using expansion cables. Additionally, the system allows for a total of 32 modules if remote options are included via Ethernet/IP or DeviceNet networks. This flexibility makes the controller suitable for medium-scale industrial applications requiring modular I/O architecture.

Question: Is the 1769-L33ER still in production?
Date Update:29/05/2025
Answer:

Yes, the 1769-L33ER is still in active production as part of the CompactLogix 5370 series. It remains a supported and widely used controller in many industrial automation systems. Rockwell Automation continues to provide firmware updates and technical support. Users can safely integrate this device into new systems.
