It is equipped with 6 status indicator lights to display the real-time operating status (operation, fault, communication, etc.).

Support programming, debugging and monitoring with Rockwell Automation Studio 5000 software.

Application scenarios

Manufacturing industry: It is used in automated production lines (such as automotive manufacturing and electronic assembly) to control robots, conveyor belts and sensors, while ensuring the safety of operators (emergency stop, protective door monitoring).

Oil and gas: Deployed in refineries or drilling platforms, manage process controls (such as valves and pumps) and achieve safety interlocks, meeting the requirements of hazardous environment certification.

Food and Beverage: Control packaging, filling and processing equipment to ensure food safety, while preventing equipment misoperation through safety functions.

Pharmaceutical industry: It is used for precise control of drug production lines (such as mixing and packaging), meeting strict compliance requirements and protecting operators and equipment through safety logic.

Water treatment and wastewater treatment: Manage pumping stations, filtration systems and chemical treatment processes to ensure process stability and operational safety.

Electricity and Energy: It is used in power plants or distribution systems to control equipment such as transformers and circuit breakers, and at the same time achieve the function of safe shutdown.

Typical applications:

Safety-critical systems: Scenarios such as emergency shutdowns, area isolation, or personnel protection (SIL 3/PLe).

Distributed control: Multi-device collaborative control is achieved through EtherNet/IP or ControlNet.
