• 3.5mm Terminal: The hub adopts 3.5mm terminal block, can be matched with OK wires, jump wires, etc., sturdy and reliable. Onboard power isolation, can achieve electrical isolation of input and output terminals, enhancing the system anti interference ability.
• Optical Isolation: Onboard opto isolation, can effectively isolate 485 master and slave devices from each other, avoiding damage to master and slave devices caused by ground potential difference, static electricity, and surges between them.
• Prevent Damage: The opto isolation also effectively avoids damage to 485 devices caused by ground current generated between devices due to ground potential differences between the master and slave devices.
• Multiple Protection: The 485 terminal is equipped with overcurrent protection, surge protection, and gas discharge protection circuits.
• Terminal Resistor Switch: Onboard 120R terminal resistor selection toggle switch, allows for the selection of whether to connect the circuit according to actual needs. The terminal resistor can increase the stability of signal transmission and reduce interference.
