Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic ^^ Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance. Onboard 15KV ESD isolation protection and 600W lightningproof & anti-surge protection ^^ Onboard 120R terminal resistor on the RS485/RS422 interface, disable by default, configurable by jumper. Onboard power supply screw terminal, allows 5V~36V DC wide range input. 3 LEDs for indicating the power and transceiver status. Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
