ماژول مبدل TTL به RS485 با MAX13487E

مدل: (CONV-00049)
وضعیت: ناموجود

Features

  1. we all chip guaranteed new imported industrial chip, ultra-long-distance transmission of up to thousands of meters .
  2. with a plus or minus of 15KV ESD protection
  3. the chip has a slew rate of the driver , the maximum reduction in the EMI , and reduced by the improper termination of the cable caused by signal reflection , so that the signal error-free transmission rates up to 500Kbps .
  4. with a 1/4 unit load receiver input impedance, support for multi-machine communication , allowing connected up to 128 devices on the bus.
  5. industrial chip temperature can reach -40 ℃ to 85 deg.] C + .
  6. the modules can be hot-swappable , hot-swap chip 485 will not be other signals appear dead bolt phenomenon.
  7. Power chip tantalum electrolytic capacitors , dual capacitors and high frequency power supply filtering
  8. using a double transient suppression diodes , overvoltage protection, better performance
  9. use 10Ω current protective resistors, chip design improves 485 Signal Integrity
  10. and has a terminal solder tail hole , easy to debug and finalize the final wiring, welding wire can improve signal reliability
  11. RS485, TTL signal all -sided alignment , signal quality, improve signal integrity
  12. a large area of copper to prevent signal interference
  13. with a 2.54 pitch plate welding tunnel hole , easy secondary development
  14. currently it has considerable popular M3 screw holes , convenient and reliable installation
  15. with a 120Ω termination resistor , shorting R16 to enable the termination resistor
  16. with the power and RXD, TXD signal lights , send and receive excellent view
  17. angled pin leads, easy to test
  18. support for 3.3V and 5V signal control system , compatibility stronger
