FMC Multi-Purpose I/O Board

The DFMC-UNI-IO is a cost-efficient FMC board designed according to ANSI/VITA 75.1. The card can be used in all applications where standard I/O channels with 3.3V or 5V levels are required. Additionally it offers analog functions needed for measurement and control tasks such as two programmable power supplies, two DACs and
two ADCs and a true RS232 UART. All IOs and all functions are routed to a CPLD where special supervision functions can be implemented and where special waveforms can be generated on the analog channels.
One use scenario of the card is the control of a laser system. The I/Os are used to for communication with a laser controller. The power source is used to drive a shutter with CPLD-generated pulse shapes. The DAC and ADC are used to drive and monitor the optocouplers in the shutters.
