PC/104 I/O Modules

PC/104 I/O modules that give a stack the measurement and control channels the application needs: 16-bit analog input and output with autocalibration, digital I/O with counters, opto-isolated inputs and relay outputs, RS-232/422/485 serial ports with optional isolation, isolated CAN bus channels and extra Ethernet ports. Each module plugs onto the PC/104, PC/104-Plus or PCI/104-Express connector of the host board and adds one 0.6-inch layer to the stack, so I/O can be added or changed without a new computer. All modules are rated for -40 to +85 °C and use latching or locking headers for vibration.

Choose by signal type, then match the module bus to the host board; our guide to the PC/104 bus variants explains which connector carries which bus, and our guide to what PC/104 is and how a stack is built covers the stack itself. We supply each module with the PC/104 single board computer and power supply it pairs with, and we configure and validate the complete stack before it ships. The wider data acquisition and I/O range includes Mini PCIe modules for hosts without a PC/104 connector.
