Colibri DIO is an expansion module that is compliant with IEC 61131-2 specification. Each I/O can either be a digital input or a digital output, and each can operate in different modes.
MAX14906 is the component that implements this standard. See its datasheet.
The max current on the output is software selectable, up to 1.2Amp, BUT that is not achievable in practice, a) the thermals don't allow it, b) the base board has a limited power supply. We recommend that the current limit is set to 100mA.
