Its 16 configurable inputs and 8 redundant outputs provide flexibility for various sensor and actuator configurations.

Secure communication capabilities: ABB LD800HSE 3BDH000320R02 features dual Ethernet ports supporting PROFINET and PROFIsafe protocols for secure communication with distributed safety devices and higher-level control systems. The integrated RS485 port with Modbus RTU enables connectivity with measurement devices like weight transmitters and process sensors, allowing safety logic to incorporate process variables. This communication flexibility ensures the controller can operate as part of a comprehensive safety system while providing visibility to operators and management systems.

Typical application scenarios

In oil and gas production facilities, ABB LD800HSE 3BDH000320R02 monitors and controls safety functions in hazardous areas such as wellheads, separation units, and storage tank farms. The controller processes inputs from gas detectors, emergency stop buttons, and pressure sensors, executing safety logic to isolate equipment, activate ventilation, or shutdown processes when hazardous conditions are detected. Integrated with ABB PFEA113-20 weight transmitters, it monitors tank levels and prevents overfilling of hazardous liquids, with its explosion-proof certification ensuring safe operation in these Zone 1 environments.

Chemical processing plants utilize ABB LD800HSE 3BDH000320R02 to manage safety interlocks on reaction vessels, mixing equipment, and material transfer systems. The controller monitors safety gate interlocks, temperature sensors, and toxic gas detectors, preventing equipment operation when unsafe conditions exist. Its Modbus RTU interface connects to weight transmitters and flow meters, enabling safety logic that incorporates process variables—for example, stopping a batch process if material dosing exceeds safe limits detected by ABB PFEA113-20 load cells. The controller’s rapid response time ensures timely activation of isolation valves and emergency shutdown systems.

Pharmaceutical manufacturing facilities deploy ABB LD800HSE 3BDH000320R02 in hazardous areas where flammable solvents are used in production processes. The controller monitors ventilation systems, access interlocks, and solvent vapor detectors, ensuring safe operating conditions. It integrates with weighing systems using ABB PFEA113-20 transmitters to ensure accurate dosing of hazardous ingredients while preventing overfill conditions. The controller’s communication capabilities allow it to share safety status with the plant’s DCS, providing operators with comprehensive visibility of both process and safety conditions.

Integration with PFEA113-20

ABB LD800HSE 3BDH000320R02 and ABB PFEA113-20 3BSE050092R20 form a powerful combination for safety-critical weighing applications in hazardous areas:

Measurement integration: The controller’s Modbus RTU interface connects directly to the PFEA113-20 weight transmitter, enabling safety logic to utilize real-time weight data for overload protection, overfill prevention, and material dosing safety functions.

Safety interlock implementation: Weight thresholds from PFEA113-20 can trigger safety outputs on LD800HSE, such as stopping conveyors when overload conditions are detected or closing valves when tank filling reaches safe limits.

Diagnostic integration: The controller monitors both safety device status and weight transmitter diagnostics, providing comprehensive fault detection and reporting for the entire measurement and safety chain.

Hazardous area compatibility: Both devices carry appropriate hazardous area certifications, ensuring safe operation in Zone 1 environments without additional protection measures.

Response coordination: LD800HSE’s rapid <5 ms response time complements PFEA113-20’s high sampling rate, ensuring timely safety actions based on dynamic weight measurements.
