Emerson KJ2201X1-JA1 is a redundant SLS terminal block exclusively designed for the DeltaV system, serving as a key component in the system’s safety instrumented setup. It operates on 30VDC, with a current rating of 30mA per channel for A-B terminal circuits and 1A per channel for A-C terminal circuits. Its redundant configuration enables automatic switching to the backup connection if the primary one fails, ensuring uninterrupted transmission of safety-related field signals to the controller. It can work stably in harsh conditions, withstanding a temperature range of -40°C to +70°C and complying with ISA-S71.04-1985 airborne contaminants class G3 standards. With an IP20 rating and no need for calibration, it is maintenance-free and seamlessly integrable with DeltaV systems. Widely used in hazardous environments like petrochemical and pharmaceutical industries, it significantly boosts the reliability of critical industrial 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.
