Technical Specifications Suitable for serial communication bus, built-in switchable terminal resistance. Operating temperature: -40℃ ~ +70℃.
Functional Features Communication signal splitting, terminal resistance switching, shielding grounding point, bus surge protection.
Application Scenarios Controller to DCS communication wiring, multi-controller load sharing bus terminal junction.
Performance Parameters Low signal attenuation, stable bus impedance, good surge protection.
Structural Characteristics Compact terminal PCB board, communication status indicator lights, terminal resistance dip switch.
Working Principle The board serves as a junction for communication bus cables. Users can switch on or off the built-in terminal resistor according to bus layout to match communication impedance.
Installation Requirements Install at one end of the communication bus for terminal matching, ground shielding layer at this board.
Usage Notes Only enable terminal resistor at the two physical ends of the bus, do not enable it on intermediate nodes.
