Diamond Systems offers a line of digital I/O modules in the PC/104 format for a range of applications.

GPIO-MM (shown in photo) is a PC/104 FPGA module offering multiple feature sets on the same hardware platform. The board provides up to 100 I/O points with buffers and ESD protection. The FPGA is a Xilinx Spartan 2 RAM-based device with 200K gates (XC2S200). An on-board configuraton flash memory device stores the FPGA code for automatic loading on power-up, and new code can be downloaded using a JTAG cable connected to a PC. Several standard off the shelf personalities are available, and custom ones can be developed either by users with Xilinx tools or by Diamond as a customization service.

Onyx-MM is a low-cost GPIO module featuring 48 digital I/O lines and 3 16-bit counter/timers. The GPIO lines are based on 2 82C55 ICs. They can be programmed for input or output in groups of 8 lines.
The 3 16-bit counter/timers are based on an 82C54 IC and can be used for counting, timing, and interrupt generation.

The Opal-MM-1616 features 16 optoisolated digital inputs and 16 relay outputs. Each input has an input range of 0-30VDC. Inputs can be configured to generate an interrupt when their state changes. The 16 relay outputs are SPDT format (form C) with 3 contacts: Common, Normally Open, and Normally Closed. Each relay can switch both AC and DC voltages.
