Schneider Electric SR3B101FU Zelio Logic SR3 10 I/O 100-240 V AC Display Relay Output Logic Module

The Schneider Electric SR3B101FU is a Zelio Logic SR3 modular smart relay with 10 I/O (6 discrete inputs, 4 relay outputs), a 100–240 V AC supply and a backlit LCD display with navigation buttons. It is a compact programmable controller for managing, monitoring and remote-controlling simple automation systems in industrial and commercial installations.

Selection Notes

The SR3B101FU runs directly from 100–240 V AC, so it suits panels without an existing 24 V DC control supply — the DC-supplied SR3B101BD instead needs a separate 24 V source but responds faster on its discrete inputs (typically ms-range versus the 50 ms/255 ms debounce built into the AC input circuit here). Both share the same 4 relay outputs rated 8 A; pick the 26 I/O SR3B261FU instead when the application needs more than 6 inputs or 4 outputs.
