Transistor outputs: 16 transistor output channels, divided into 2 groups of 8 each, also electrically isolated.

Digital input/output combinations: 1 group of 8 electrically isolated digital input/output channels.

Analogue input: 1 group of 8 analogue input channels can be individually configured as 0...10V, 0...5V, +10V, +5V, 0...20mA, 4...20mA, Pt100 (2-wire or 3-wire), differential inputs and other types of signals, which can be flexibly connected to various analogue sensor signals. Flexible access to a variety of analogue sensor signals.

Communication interface: support CS31 system bus, can achieve seamless integration with other equipment, easy to build distributed control system, data interaction and cooperative work.

Protection Functions: Built-in comprehensive protection functions, including over-current, over-voltage, under-voltage, temperature protection, as well as fault diagnosis and recovery mechanism, which can effectively prevent the equipment from being damaged due to abnormal conditions and improve the reliability and stability of the system.

Application Fields

Industrial automation: In various industrial production processes, such as chemical, pharmaceutical, food and beverage industries, it can be used as the core control unit to achieve precise control and monitoring of production equipment to ensure the efficient and stable operation of the production process.

Energy management: applicable to the control and management of energy systems, such as boiler heating, water treatment and other fields, through the monitoring and control of the relevant parameters, to achieve the rational use of energy, improve energy efficiency and reduce energy consumption.

Municipal engineering: It can be applied to the control of relevant equipment in municipal engineering, such as water supply, drainage, sewage treatment and other systems, to ensure the normal operation of municipal facilities.

FEATURE

• Low-impedance busbar protection 

• Stub and T-zone protection 

• High functional reliability due to two independent measurement criteria: 

- stabilized differential current algorithm 

- directional current comparison algorithm 

• Phase-by-phase measurement 

• Reduced CT performance requirements 

• High through-fault stability even in case of  CT saturation 

• Full solid-state busbar replica 

• No switching of CT circuits 

• Only one hardware version for  

- 1 and 5 A rated currents 

- all auxiliary supply voltages between  48 V DC and 250 V DC 

- nominal frequencies of 50, 60 and  16.7 Hz 

• Short tripping times independent of the  plant’s size or configuration 

• Centralized layout: Installation of hardware  in one or several cubicles 

• Distributed layout: Bay units distributed  and, in the case of location close to the  feeders, with short connections to CTs, isolators, circuit breakers, etc. 

• Connections between bay units and central  unit by fiber-optic cables 

- maximum permissible length 1200 m  

- for distributed and centralized layout 

• fiber-optic connections mean interference proof data transfer even close to HV power  cables 

• Replacement of existing busbar protection  schemes can be accomplished without restrictions (centralized layout) in the case of  substation extensions e.g. by a mixture of  centralized and distributed layout 

• Easily extensible
