Overview of MOXA CI-134 Series

MOXA CI-134 Series is a multiport serial communication solution designed for industrial PCs using a 16-bit ISA bus. The series provides four independent RS-422/485 serial ports for connecting industrial controllers, instruments, terminals, and other serial devices to a host computer. The boards support communication speeds from 50 bps to 921.6 kbps and include 16-byte FIFO buffers with on-chip hardware flow control. DB37-to-DB9 connections provide practical access to the serial ports for Industrial Communication and automation equipment.

MOXA CI-134 Series Features

MOXA CI-134 Series is designed for industrial computers that require multiple serial interfaces for Industrial Automation and data acquisition. The four independent ports can connect multiple RS-422 or RS-485 devices to a single PC for monitoring, control, and data exchange. The boards support RS-422, RS-485 4-wire, and RS-485 2-wire communication modes. This allows integration with serial controllers, meters, sensors, terminals, and other field equipment. Applications can include SCADA systems, machine control, industrial monitoring, and legacy automation installations where reliable serial connectivity is required.
