The Mitsubishi FX1N-2AD-BD is an analog input expansion board for the FX1N series PLC. It adds 2 channels of analog input that accept either voltage or current signals — and both types can be used together on the same board, which gives flexibility when mixing sensor types on a single machine. The board mounts directly onto the FX1N base unit, so it takes no additional DIN-rail space or enclosure depth — a clean fit when the panel layout is already tight.
