The Moxa CP-118U-I-T is a rugged 8-port Universal PCI serial board, designed for demanding industrial automation applications requiring reliable serial communication under extreme conditions. It supports RS-232, RS-422, and RS-485 protocols with data rates up to 921.6 kbps and provides 2 kV optical isolation to protect systems from electrical interference.

With an extended operating temperature range of -40 to +85 °C, this board is ideal for outdoor enclosures, machine control cabinets, or industrial IT environments. Broad driver support across Windows, Linux, and UNIX platforms ensures high compatibility. Per-port LEDs for transmit and receive activity simplify diagnostics and maintenance.
