1. WITH INDICATOR: With TVS transient suppression function to prevent the internal chip from being damaged due to level incompatibility, with receiving and sending lights, to high pulse voltage function, and super convenient wiring method
2. OVERVOLTAGE TRANSIENT : , electrostatic discharge , , overvoltage and other transient disturbances caused by power system switches, etc. For these transient disturbances, using protective circuits to protect, bypassing the harmful transient energy to ground
3. 115200BIT ERROR TRANSFER: Completely designed in accordance with industrial grade standards, which has and static shock , limited slope drive, effectively suppresses electromagnetic interference and solves the superposition of valid and invalid on the circuit. Error data transfer rate up to 115200bit
4. EFFECTIVE SUPPRESSING EFFECT: On board TVS(transient voltage ), effectively suppressing voltage and transient spike voltage in the circuit
5. SUPPORT UP TO 32 TRANSCEIVERS: The has 1/8 unit load input impedance, and up to 32 transceivers can be attached to the bus
