RS422 Mutual Conversion TTL Two-way Signal Module

RS422 Mutual Conversion TTL Two-way Signal Module/Full Duplex 422 Turn Single Chip MAX490 To TTL Module

Description

RS422 interface, two-way communication.A B Y Z ultra far transmission 1000 meters.The module has ESD 15KV protection.On board to increase the limit of 10 ohm current limiting current protection.Module with TVS diode. Anti lightning peak voltage.The module has 120 ohm termination resistors, which can effectively reduce the interference of long range communication.Have the power indicator light and the data receiving and sending indicator light. Panoramic view of state data.Module TTL side using 5V DC power supply TXD RXD compatible with 5V logic signal.Module uses the original imported MAX490 chips, stability and communication speed is far more than domestic products, up to 25MBPS.
Module size: 50.00mm*27.30mm

Interface

RXD receiver output: If A > B 200mV, then RXD is high; If A TXD driver input: The low level forced output Y on TXD is low, while the output Z is high. Similarly, the high level on the TXD forces Y to be high and the output Z to be low.

• A: Receiver in-phase input
  
• B: Receiver inverting input
  
• Y: Driver in-phase output terminal
  
• Z: Driver inverting output terminal
