Emerson KJ2221X1-BA1 is a SISNet repeater module specially designed for the DeltaV system, dedicated to boosting reliable Foundation Fieldbus communication in industrial safety instrumented systems (SIS). It works with a 24VDC power supply (20 – 30VDC range) and can connect up to 96 field devices via four independent H1 channels (24 devices per channel). Featuring a 2000V AC field – to – system isolation barrier, it effectively avoids signal interference and ensures stable data transmission. It operates stably in the temperature range of -25°C to +80°C and is certified with ATEX II 3 G and SIL 3, being suitable for Class I, Division 2 hazardous areas. As a key component for extending SIS network coverage, it is widely used in petrochemical, chemical and power industries to support secure communication for critical process monitoring and control systems.
Emerson’s Ovation system is a distributed control system (DCS) specifically designed for the power generation and water/wastewater treatment industries. As a reliable innovation platform, it provides comprehensive control capabilities and powerful system integration. The main components of Ovation system include:
1. Host: It is the core of the entire system, responsible for data processing, storage, and forwarding, as well as controlling the execution of logic.
2. Screen: It is an interface for users to interact with the system, used to display real-time data, alarm information, trend charts, etc., and allows users to set parameters and control operations.
3. Sound system: Provides sound alarm function. When the system detects abnormal situations or faults, it will emit sound prompts through the sound system, so that operators can respond in a timely manner.
4. Projector: In some applications, it may be used for large screen display, allowing multiple people to simultaneously view system status and operation information.
5. Touch devices: such as touch screens, provide an intuitive operating interface, allowing users to easily perform various controls and settings.
6. Control system: including control logic, algorithms, and strategies, used to achieve precise control of industrial processes.
7. I/O modules and interfaces: used for connecting and exchanging data with external devices such as sensors, actuators, etc. These modules can convert signals from external devices into digital signals that the system can recognize, or convert control signals from the system into instructions that external devices can execute.
8. Communication and network equipment: Ensure data communication and information sharing between internal components of the system and between the system and other external systems.
9. Software and firmware: including operating systems, control software, databases, etc., to provide necessary support and guarantees for the normal operation of the system.
