Description
Product Name: 1747-L20P Allen Braley Central control module
Product details:
Allen-Bradley is the flagship brand of programmable logic controllers (PLCs) and automation components from Rockwell Automation. Known for their reliability and deep integration within industrial ecosystems, they are a global standard in manufacturing.
1. Product Categories & Overview
Allen-Bradley offers a scalable portfolio categorized primarily by the complexity of the application:
-
ControlLogix® (Large Systems): Designed for high-performance, high-capacity, and multidisciplinary control (discrete, motion, process).
-
CompactLogix™ (Mid-range): Offers the same programming environment as ControlLogix but in a smaller, more cost-effective form factor.
-
Micro800® (Small/Micro): Modular, customizable controllers for standalone machines and small-scale automation.
-
SLC™ 500 & PLC-5®: Legacy systems, many of which are now phased out but still found in older installations.
2. Key Product Parameters (General)
While specific specs vary by model, common parameters for modern Logix-based controllers include:
| Parameter | ControlLogix (5580) | CompactLogix (5380) |
| User Memory | 3MB to 40MB | 0.6MB to 10MB |
| Communication | Integrated 1Gbps Ethernet port | Dual 1Gbps Ethernet ports |
| I/O Support | Up to 128,000 points | Up to 31 local modules |
| Motion Control | Up to 256 axes | Up to 32 axes |
| Safety | SIL 2/3, PLe Cat. 4 (GuardLogix) | SIL 2/3, PLe Cat. 4 (GuardLogix) |
3. Product Advantages
-
Integrated Architecture: Uses the Studio 5000 Logix Designer® environment. Once you learn one Logix controller, you can program almost any of them.
-
EtherNet/IP Prowess: Industry-leading implementation of EtherNet/IP, allowing seamless communication between controllers, HMI (Human Machine Interface), and drives.
-
Scalability: You can easily migrate code from a small CompactLogix system to a massive ControlLogix plant-wide system.
-
Security & Safety: Built-in “CIP Safety” and hardware-based digital signing of firmware provide high levels of industrial cybersecurity.
-
Global Support: Extensive documentation, training, and a massive network of distributors and system integrators.
4. Considerations & Precautions (Precautions)
-
Environment: Ensure the PLC is installed in a NEMA/IP-rated enclosure to protect against dust, moisture, and extreme temperatures.
-
Firmware Compatibility: Always verify that your Studio 5000 software version matches the hardware firmware version (Revision).
-
Licensing Costs: Software licenses (Studio 5000) are an additional cost and are often tiered based on features (Standard, Professional, etc.).
-
Power Supply: Use a clean, regulated 24V DC power source. Industrial environments are prone to electrical noise which can cause CPU faults.
-
Static Discharge: Always ground yourself before touching internal modules to prevent Electrostatic Discharge (ESD) damage.
5. Product Applications
Allen-Bradley PLCs are found in virtually every industrial sector:
-
Automotive: Robotic assembly lines, paint shops, and welding cells.
-
Food & Beverage: High-speed bottling, packaging, and batch mixing.
-
Oil & Gas: Pipeline monitoring, offshore rig safety systems, and refinery control.
-
Pharmaceutical: High-precision dosing and strictly regulated batch reporting (CFR 21 Part 11).
-
Water/Wastewater: Pump station management and treatment plant automation.
