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.
