Overview
The SR2PACK2FU is a Schneider Zelio Logic smart relay packing 12 discrete inputs and 8 relay outputs on a 100-240 VAC supply, with a built-in real-time clock and USB programming via the included cable. It is non-expandable and sealed to IP20 (IP40 on the front face), fitting a DIN-rail panel.
Compared to the SR2PACKFU, the SR2PACK2FU adds 4 more discrete inputs (12 vs 8) and 4 more relay outputs (8 vs 4), and is non-expandable — the SR2PACKFU can accept expansion modules. Choose the SR2PACK2FU when the I/O count is fixed and you need the higher density in a single base unit.
