The XPort9100 is a rugged, avionics-level GPIO XMC module. The XPort9100 provides eight independently configurable GPIO channels, each optically isolated. Each output is open-drain and, when active, is clamped to the return line voltage. The output can support clamping a 0.3 A pull-up. Each input has a +3.5 V switching threshold. The XPort9100 requires XMC VPOWER to be at +12 V. Please contact X-ES for +5 V VPOWER support.
