Module truyền thông 4 cổng RS-422/485 cách ly ICP DAS I-8144iW

Features

  • High-profile Module

  • Serial Port with +/-4 kV ESD Protection

  • Baud Rate of up to 115200 bps

  • Built-in Self-Tuner or Auto-Direction Control

  • Low power consumption

  • 2500 Vrms Isolation

  • Internal 128-byte Hardware FIFO for each Port

  • LED Indicators for TxD, RxD and Power Status

  • RoHS Compliant & no Halogen

  • Made from fire-retardant materials (UL94-V0 Level)

Introduction

The I-8142iW-G provides 2 isolated RS-422/485 serial ports, while the I-8144iW-G provides 4 isolated RS-422/485 serial ports. It is equipped with a 128-byte hardware FIFO for each port and offers speeds up to 115.2 kbps with support for RS-422 full-duplex communication.

In the harsh industrial environment, the onboard ESD protection devices can divert this potentially damaging charge away from sensitive circuitry and protect the 
I-8142iW/I-8144iW from permanent damage.

The serial communication modules are designed for use with intelligent devices like bar code readers, serial printers, intelligent sensors, instrumentation equipment, computers, and almost any device with an RS-422/485 port.

Software

  • Supports interrupt driven software library

  • Supports VxCOM library
