The Moxa CP-134U Series is a high-performance 4-port Universal PCI serial board designed for industrial applications requiring long-distance and multipoint PC-based data acquisition. Two of the four ports support RS-232/422/485, while the other two support RS-422/485 only, offering flexible connectivity options for various industrial scenarios.

Equipped with ADDC® (Automatic Data Direction Control), the CP-134U makes RS-485 communication as simple and seamless as RS-232. The CP-134U-I model features 2 kV electrical isolation to protect connected devices from electrical surges. Its Universal PCI compatibility (3.3/5 V and PCI-X) and optional wide-temperature model (-40 to 85 °C) make it suitable for diverse industrial environments.
