The AIM104-MULTI-I/O is an 8-bit PC/104 module providing eight opto-isolated digital inputs, two analogue outputs (voltage or current loop), and sixteen single ended or eight differential analogue inputs. The board includes jumper options to select all analogue inputs as sixteen single-ended or eight differential.
Isolation
It provides up to 1000V electrical isolation between the PC/104 based control system and the electrical system under control. Isolation between adjacent channels is limited by the wiring and connectors to 30V.
All digital inputs include a fixed 10ms debounce filter.
