Description

UNITROL 1020 UNS0119A-Z,V1 3BHE030579R0003

UNITROL 1020 is a voltage regulator designed for small and medium-sized synchronous generators and industrial equipment in UNITROL1000 series. UNITROL 1020 combines performance control and simple design of power circuit.

UNITROL 1020 is a powerful small indirect excitation system with built-in support for dual channels, which is used for advanced load distribution, rotating diode monitoring, automatic synchronization and multiple integrated communication options in parallel operation units.

UNITROL 1020 is a voltage regulator designed for small and medium-sized synchronous generators and industrial machines in the UNITROL 1000 series. IGBT semiconductor device based on advanced microprocessor technology and current output up to 10 ADC for continuous operation. UNITROL 1020 can perform high performance work under harsh conditions and different temperature ranges, and fully complies with DNV and UL standards. The additional features of UNITROL 1020 compared with previous versions are Ethernet, USB connection, data and event recording and many new functions.

Fieldbus is a two-way serial, digital and multi-node communication network connecting field intelligent equipment and automatic control equipment. It is also known as the field bottom device control network (INFRANET). Since the 1980s, various fieldbus technologies have begun to appear, and people have increasingly demanded the reform of traditional analog instruments and control systems, which has made fieldbus become a worldwide wave of technological change. The American Instrument Association (ISA) began to formulate fieldbus standards in 1984. In Europe, there are PROFIBUS in Germany and FIP in France. Various fieldbus standards have been formed in succession. The main ones are Foundation Fieldbus FF (Foundation Fieldbus), Controller Area Network CAN (Controller Area Network), Local Operating Network LonWorks (Local Operating Network), Process Fieldbus PROFIBUS (Process Fieldbus) and HART protocol (Highway Addressable Remote Transmitter). However, the development of fieldbus standards is not smooth. Due to historical reasons such as industry and regional development, as well as the drive of companies and enterprise groups by their own interests, the progress of fieldbus internationalization standards is slow. However, it is inevitable to develop a single open international fieldbus standard.

PROFIBUS is a field bus in accordance with the German national standard DIN19245 and the European standard EN50179, including PROFIBUS-DP, PROFIBUS-FMS and PROFIBUS-PA. It also only uses the physical layer, data link layer and application layer of OSI model. PROFIBUS supports master-slave mode, pure master-slave mode and multiple master-slave communication mode. The master station has control over the bus, and the master stations transfer control over the bus by passing tokens. The master station that obtains control can send and obtain information from the slave station. PROFIBUS-DP is used for high-speed data transmission between distributed peripherals and is suitable for processing automation. FMS type is applicable to textile, building automation, programmable controller, low-voltage switch, etc. The PA type is the bus type used for process automation.
