AIM104-OPTO-IN8/OUT8 is a low cost add-on PC/104 module providing eight optoisolated inputs and eight opto-isolated outputs.
The inputs can be driven by an external power source or can be configured to use an on-board isolated +24V DC excitation supply. AC opto-isolators are used to allow each input channel to detect either rising or falling edges through jumper configuration. 10ms RC debounce filters are also link selectable on each input channel.
The outputs are configured as current sourcing drivers with a drive capability of up to 700mA.
There is only one standard variant of this board, referred to as the AIM104-OPTOIN8/OUT8.
Isolation
The module provides up to 2500V electrical isolation between your PC/104 based control system and the electrical system you are controlling. The isolation between adjacent channels is limited by the wiring and connectors to 100V.
