Overview
The SR2D201FU is a Zelio Logic smart relay from Schneider, packing 12 discrete inputs and 8 relay outputs in a compact DIN-rail housing, powered by 100-240 VAC at 50/60 Hz. It carries no real-time clock and runs a program memory check on each power-up, suiting it for simple sequencing or combinational logic where time-stamped events aren't needed.
Compared to the SR2D101FU, the SR2D201FU doubles the I/O: 12 inputs and 8 relay outputs versus 6 inputs and 4 relays, making it the right choice when the panel needs more than 10 I/O points without adding an expansion module.
