Allen-Bradley 1769-L38ERMS Compact GuardLogix 5370 processor

Here is the parameter introduction of Allen-Bradley 1769-L38ERMS:

General Information

• Catalog Number: 1769-L38ERMS.

• Module Type: It belongs to the Compact GuardLogix 5370 series of processor modules.

Memory

• User Memory: It has 4 MB of user - accessible memory for storing programs, data, and configurations related to the control application.

• Non - Volatile Memory: Comes with a 2 - GB Secure Digital (SD) card. This card is used for data logging, program backup, and storing other essential information. The SD card can be replaced or upgraded for additional storage capacity if needed.

Communication Ports

• Ethernet Ports: There are two Ethernet ports. These ports support multiple network topologies like linear and Device - Level Ring (DLR). They enable the processor to communicate with other devices in the industrial network, such as other PLCs, HMIs, and various automation equipment, using protocols like Ethernet/IP for efficient data exchange and device interoperability.

• USB Port: One USB port is available. It is mainly used for initial program download, firmware updates, and for connecting to external devices like programming laptops or portable storage devices, providing a convenient local connection for data transfer and configuration.

I/O Modules Support

• The 1769-L38ERMS can support up to 32 I/O modules. It is compatible with a wide range of Compact I/O modules, allowing for highly flexible system expansion to meet diverse input and output requirements, such as connecting different types of sensors, actuators, and other peripheral devices.

Motion Control Capability

• It supports up to 16 - axis CIP motion control. This makes it suitable for complex motion control applications that require precise coordination and control of multiple axes, such as in advanced robotic systems, multi - axis machining centers, and other industrial equipment where accurate motion profiling and positioning are crucial.

Safety Features

• The processor is equipped with integrated safety functions and is certified for use in applications with Safety Integrity Level 3 (SIL 3) and Performance Level (PL) E. It can be used to implement safety - critical control systems that meet strict industrial safety standards and regulations.

Mechanical Specifications

• Mounting: It can be mounted on a DIN - rail or a panel. The DIN - rail mount is convenient for standard industrial enclosure installations, while the panel mount option offers more customization for specific installation requirements.

• Dimensions: The module measures approximately 118 mm in height, 55 mm in width, and 105 mm in depth, making it suitable for installation in relatively compact spaces within control panels or in applications where space is at a premium.

• Weight: The approximate weight of the module is 0.35 kg, which is lightweight and easy to handle during installation and maintenance procedures.

Environmental Conditions

• Operating Temperature: The operating temperature range is 0℃ to 60℃ (32℉ to 140℉). This allows the processor to operate reliably in a variety of industrial environments, provided that proper ventilation and cooling are maintained to prevent overheating.

• Storage Temperature: The storage temperature range is - 40℃ to 85℃ (- 40℉ to 185℉), enabling the module to be stored in different environmental conditions before installation or during periods of non - use.

• Relative Humidity: The relative humidity range is 0% to 95% non - condensing, ensuring that the processor can function in high - humidity environments without the risk of condensation - related damage to the electronic components.
