USB to RS485 Converter with TV Transient Suppression Protection Signal Indicator for Windows

Features: 1. WITH SIGNAL INDICATOR: With TVS transient protection to prevent damage to the internal chip due to level incompatibility, it supports receiving and sending signals, resists high impulse voltages, and offers a super convenient wiring method. 2. TRANSIENT SURGE PROTECTION: Protects against lightning, electrostatic discharge, power surges, and other transient disturbances caused by power system switches, etc. It uses protective circuits to prevent harmful transient energy from being transmitted to ground. 3. ERROR-FREE TRANSFER 115200BIT: Fully designed according to industrial quality standards, it is lightning and static shock resistant, with a limited slope drive. It effectively suppresses electromagnetic interference and resolves the overlap of valid and invalid signals on the transmission circuit. Error-free data transfer rate up to 115200bit4. EFFECTIVE SUPPRESSION EFFECT: Built-in TVS (transient voltage suppressor), effectively suppressing transient voltage surges and spikes in the circuit5. Supports up to 32 transceivers: The receiver has a load input impedance of 1/8 unit, and up to 32 transceivers can be attached to the bus.
