Honeywell LG1093AC01

Product introduction

The Honeywell LG1093AC01 is an advanced industrial process controller designed to handle complex multi-variable processes in demanding manufacturing environments. As a premium model in Honeywell’s Experion series, it builds on the capabilities of controllers like the EG1033AC01 with expanded I/O capacity, advanced control algorithms, and enhanced connectivity—making it ideal for large-scale production lines and precision-critical applications.

Honeywell LG1093AC01 excels in regulating interrelated process variables such as temperature, pressure, flow, and level, where changes in one parameter affect others. Its 7-inch multi-touch screen provides comprehensive process visualization, while support for advanced communication protocols enables seamless integration with enterprise systems. Whether deployed in petrochemical refining, semiconductor manufacturing, or high-volume pharmaceutical production, Honeywell LG1093AC01 delivers superior control precision, helping to maximize yields, ensure regulatory compliance, and reduce operational costs.

Core advantages and technical highlights

Multi-loop control capability: LG1093AC01 features 9 universal inputs and 6 outputs, enabling simultaneous control of up to 6 independent loops or complex interlocked processes. Unlike single-loop controllers, it can manage interacting variables—for example, in a distillation column, it regulates reboiler temperature, column pressure, and overhead product flow, adjusting each parameter to maintain product purity. This integrated approach eliminates the inefficiencies of separate controllers and reduces system complexity.

Advanced control algorithms: Beyond standard PID, LG1093AC01 incorporates Model Predictive Control (MPC), which uses mathematical models to anticipate process behavior and adjust outputs proactively. This is particularly valuable for processes with dead times or nonlinear responses, such as batch reactors or extrusion lines. MPC reduces overshoot by up to 50% compared to conventional PID, ensuring tighter control of critical parameters like chemical reaction temperatures or polymer melt viscosity.

Regulatory compliance features: With FDA 21 CFR Part 11 certification, LG1093AC01 includes audit trails, electronic signatures, and secure data storage—essential for regulated industries like pharmaceuticals and biotechnology. It automatically logs process data with time stamps, generating reports that simplify compliance with FDA, EMA, and other regulatory bodies. The controller’s access control system restricts parameter changes to authorized personnel, preventing unauthorized modifications to critical process settings.

Enhanced connectivity and scalability: LG1093AC01 supports Modbus, BACnet/IP, and optional Wi-Fi, enabling integration with SCADA, MES, and ERP systems. It can communicate with up to 32 remote I/O modules, expanding its monitoring capacity to over 100 points for large facilities. In a chemical plant, this allows the controller to coordinate operations across multiple reactors, sharing data with the enterprise resource planning system to optimize raw material usage and production scheduling.

Typical application scenarios

Petrochemical refineries utilize LG1093AC01 to control distillation units, where it regulates column temperature, pressure, and reflux flow across multiple stages. The controller’s MPC algorithm adjusts these variables in real-time to maintain product specifications (e.g., octane levels in gasoline) despite fluctuations in feedstock composition. Its 7-inch screen displays trending data for each loop, while Ethernet connectivity sends key metrics to the plant’s DCS for centralized monitoring.

Semiconductor manufacturing facilities deploy LG1093AC01 in chemical vapor deposition (CVD) processes, where precise control of temperature (±0.1°C), pressure (±0.1 torr), and gas flow is critical for wafer quality. The controller’s 9 inputs monitor process variables and chamber conditions, while outputs adjust heaters, vacuum pumps, and mass flow controllers. Its FDA 21 CFR Part 11 compliance ensures detailed process records are maintained for quality control audits.

Food processing plants use LG1093AC01 in large-scale pasteurization systems, where it coordinates heating, cooling, and flow rates across multiple processing stages. The controller’s auto-tune function adapts to varying product volumes, while relay outputs manage pumps and valves to maintain consistent pasteurization times. Integration with plant-wide MES via Modbus TCP/IP allows for recipe management, enabling quick product changeovers with minimal downtime.
