This is a Mitsubishi FX2NC-32EYT — an output-only extension block for the FX2NC series, packing 32 transistor-sourced (source) channels on a ribbon cable connector. At 0.7 W power consumption and 100 mA current draw from the backplane, it's a low-power slice meant for high-speed DC switching, not relay loads.
Integration brief
Connection is via the ribbon cable connector native to the FX2NC base unit. Supports up to 2 blocks connected, so plan the expansion slot order. The 32 channels occupy 32 I/O points on the PLC. Physical dimensions are 2.62 x 9 x 8.7 inches — verify panel cutout against the base unit clamping.
