ABB TB807 module bus terminal resistance
ABB TB807 is a module bus terminal resistor with part number 3BSE008538R1.
Function: Mainly used to absorb the signal reflection at the end of the module bus, prevent signal distortion, ensure clear and accurate data signals, and maintain the reliability of communication in ABB control system. For example, in a complex industrial automation control system, if there is no TB807 terminal resistance, the signal may be reflected back after transmission to the end of the module bus, and the subsequent signal interference, resulting in data errors or communication interruption, and TB807 can effectively avoid this situation.
Electrical characteristics: Usually has a specific resistance value to match the characteristic impedance of the module bus to achieve the best signal transmission. Although the specific resistance value is not explicitly given, it is generally designed according to the standards of ABB module buses to ensure compatibility and match with the bus system.
Physical characteristics: The size is 17mm wide, 13mm deep, 19mm high, weight is about 10g, small size, easy to install on the bus cable, does not take up too much space, and no external power supply, plug and play, convenient and fast.
Environmental adaptability: Operating temperature is 0 ° C to + 55 ° C, storage temperature is -25 ° C to + 70 ° C, relative humidity is 5% to 95% non-condensing, in line with CE certification, with good electrical safety performance, can be adapted to a variety of industrial environments
