SCM TTL to RS485 Automatic Flow Control Module 485 Serial UART Level Mutual Electricity Converter

About this item

• Feature: 1. With positive and negative 15KV ESD protection, the chip has a limited slew rate driver to minimize EMI and reduce signal reflections caused by improper terminal matching cables, thereby enabling errorfree signal transmission rates up to 500Kbps. 2. The input impedance of the receiver with a 14 unit load supports multimachine communication, allowing connection to a bus of up to 128 devices. 3. Using 10 Ohm current protection resistors, patch design to improve 485 signal integrity. 4. With terminals and welding holes, convenient debugging and final fixed wiring, welding s can improve signal reliability. 5. Welding holes with 2.54 pitch holes for easy secondary development. With M3 screw holes that are quite commonly used at present, easy and reliable installation. 6. With 120 Ohm termination resistance, shortcircuit R16 to enable termination resistance.With power supply and RXD, TXD signal indicator, the receiving and sending status can be seen at a glance. 7. Angled pin s for easy testing, support 3.3V and 5V signal control, more compatible.
