EXSYS EX-1334V Industriële 4-poorts USB naar RS-232 seriële adapter met FTDI-chipsets, 15kV ESD-beveiliging, metalen behuizing

Four independent RS-232 ports at up to 921.6 Kbps each—this EXSYS EX-1334V turns a single USB 2.0 connection into a quad-channel serial powerhouse. Built around the FTDI FT4232HL controller, it delivers rock-solid compatibility and sustained throughput for industrial automation, POS systems, and legacy device integration.

Overview

The EX-1334V is a rugged USB-to-serial adapter that provides four DB9 male RS-232 ports from one USB Type-B host connection. It supports data rates up to 921.6 Kbps per port, with full modem control and hardware/software flow control. The metal housing and wide operating temperature range (-40°C to 85°C) make it suitable for harsh environments, while 15kV ESD protection and surge protection safeguard connected equipment. Bus-powered operation eliminates the need for an external supply in most setups, though an optional 5V DC input is available for power-hungry applications.
