What it is and what it does
The Fuji Electric SZ-GM/N2S-24 is a programmable logic controller (PLC) that runs on 24-26V at 60Hz or 24V at 50Hz. It's built for control-panel duty in industrial automation, handling logic, timing, and sequencing for machines and processes. Rated for 24-26V 60Hz / 24V 50Hz, so it'll sit happy on a standard 24V DC control supply or a 24V AC transformer, depending on your plant's frequency.
