1769-L33ER Product Overview
The Allen Bradley 1769-L33ER is a high-performance programmable automation controller (PAC) from the CompactLogix 5370 L3 series, developed by Rockwell Automation for small to medium-sized industrial control applications. It combines compact design with advanced functionality, making it a reliable core component for automating complex machine operations and industrial processes while saving panel space in electrical enclosures.
Key Technical Specifications & Features
- Processing Power: Built with a 32-bit RISC processor (or 1GHz ARM Cortex-M7 kernel) and 100 MHz PowerPC 405, delivering fast boolean instruction execution speed of 0.22 µs/instructions, capable of handling complex logic, sequential control, and motion control tasks effortlessly.
- Memory Configuration: 2MB user memory for program, data, and tag storage, paired with 1GB non-volatile storage (expandable to 2GB via SD card) and 256KB RAM for runtime data caching. No battery required for memory retention, ensuring data safety during power outages with internal energy storage.
- Communication Capabilities: Integrated dual Ethernet/IP ports (10/100 Mbps) supporting linear, star, and Device Level Ring (DLR) topologies for enhanced network reliability. Also features 1 USB port for easy programming and configuration. Compatible with CIP Sync, CIP Motion, and Modbus TCP protocols, enabling seamless data exchange with HMIs, SCADA systems, and other PLCs.
- I/O Expansion: Supports up to 16 local 1769 series I/O modules and 3 expansion banks (total 30 modules including power and communication modules), scalable to thousands of digital and analog I/O points. Ideal for systems requiring flexible expansion for sensors, actuators, and other field devices.
- Motion Control: Enables 8-axis servo motion control (expandable to 16 axes) without additional controllers, supporting point-to-point positioning, electronic gearing, and cam functions. Perfect for robotics, CNC machines, and precision assembly lines.
- Safety & Certification: SIL 3 (IEC 61508) and PLe (ISO 13849) certified, with safe torque off (STO) and fail-to-safe (SFS) features, suitable for safety-critical applications. Complies with UL, CSA, GOST, and KC standards for global industrial use.
- Installation & Programming: DIN rail or panel mountable, with a compact form factor for easy integration into tight spaces. Programmable via Studio 5000 Logix Designer, supporting IEC 61131-3 languages (ladder logic, structured text, function block diagram) for flexible programming.
Application Scenarios
The 1769-L33ER is widely used in various industrial sectors, including: packaging machinery (high-speed packaging line coordination), material handling (multi-device synchronization via Ethernet), water treatment (water quality monitoring and equipment control), assembly lines (precision multi-axis motion control), and OEM equipment (standardized control solutions with expandable interfaces).
Quality & Warranty
Genuine Allen Bradley product, brand-new with original packaging. Backed by a 12-month manufacturer warranty, ensuring reliable performance and after-sales support. Each unit undergoes strict quality inspection to meet industrial automation standards, suitable for long-term continuous operation in harsh industrial environments (operating temperature: 0°C to 60°C, humidity: 5% to 95% non-condensing).
