US Serial I/O Modules
Serial I/O modules and cards for instruments, PLCs, GPS receivers, radios and legacy equipment that still talk RS-232, RS-422 or RS-485. The range covers 4 and 8-port boards for PC/104, PC/104-Plus and PCIe/104 hosts and 4-port PCIe MiniCards, with opto-isolated options that protect the host from ground loops and surges, software-selectable protocols and latching connectors for high-vibration installs. All are rated for -40 to +85 °C.
We supply serial modules with the host board they belong to and the power supply that feeds it, with the host computer configured and validated by us before it ships.
