Schneider Electric SR1A201FU Smart Relay Programmable Module

Schneider Electric's SR1A201FU Zelio Logic smart relay is a compact 20‑I/O programmable module for standalone equipment and small automation projects, integrating 12 digital inputs and 8 relay outputs. It operates from 100–240 V AC (50/60 Hz), can switch 24 V DC or 24–250 V AC on its relay outputs, and provides an 8 A at 240 V AC rating with an integrated LCD display for local status. Programming is done in Ladder Diagram or Function Block Diagram using Zelio Soft, and the device mounts on a 35 mm DIN rail for control panels, packaging machines, conveyors, HVAC equipment, pumping stations, and similar industrial systems. This model is discontinued and its recommended successor is the Schneider Electric SR2A201FU.
