Frequently Asked Questions about 1769-L38ERM
Question: What is the 1769-L38ERM controller?
Date Update:20/06/2025
Answer:

The 1769-L38ERM is a CompactLogix 5370 L3 series programmable automation controller (PAC) from Rockwell Automation. It supports integrated motion control, multiple communication protocols, and is widely used in mid-range automation applications.

Question: How many remote 1769 I/O banks does it support?
Date Update:20/06/2025
Answer:

The 1769-L38ERM supports up to three I/O banks using 1769-AENTR Ethernet adapters. These allow expansion of I/O over EtherNet/IP, enabling flexibility in distributed control systems.

Question: What modules is the 1769-L38ERM compatible with?
Date Update:20/06/2025
Answer:

The 1769-L38ERM is compatible with:

  • 1769 Compact I/O modules
  • POINT I/O and FLEX I/O (via EtherNet/IP adapters)
  • Kinetix 350/5500/5700 (for motion over EtherNet/IP)
  • PanelView Plus HMIs, and third-party Ethernet devices

It supports up to:

  • 32 1769 I/O modules in a local chassis
  • 31 EtherNet/IP nodes
  • 16 motion axes over EtherNet/IP
Question: What is the temperature rating of the 1769-L38ERM?
Date Update:20/06/2025
Answer:
  • Operating temperature: 0 to 60°C (32 to 140°F)
  • Storage temperature: -40 to 85°C (-40 to 185°F)
  • Relative humidity: 5% to 95% non-condensing

These ratings meet standard industrial control cabinet environments.

Question: What is the power consumption of the controller?
Date Update:20/06/2025
Answer:
  • Base power consumption: approximately 3.5 W to 4.5 W (varies with configuration)
  • Backplane current draw:
    5V DC: 1.2 A
    24V DC: Not applicable (uses external supply)

Always check the cumulative power usage when designing systems with multiple modules to avoid overloading the power supply.
