The CompactPCI analog I/O board CPCI-3120 has 16 SE/8 differential inputs, 16-bit, with a througput rate of 100 kHz. The 8 analog ouputs have a 14-bit resolution. All output lines are protected against short-circuits and equipped with EMI filters. Each output has its own ground line. The 24-bit timer can be used as cyclical counter or as watchdog. The board is especially suited for applications in the sector of industrial process control, measurement technology and monitoring, for example for multichannel data acquisition, for the control of chemical processes, for the acquisition of sensor data etc.

NEW: The CPCI-3120 is now operating in the  extended temperature range -40°C to +85°C
