Schneider Electric SR2B201BD Zelio Relay

Schneider Electric SR2B201BD Zelio Logic compact smart relay is a DIN-rail mounted control device in the Zelio SR2/SR3 family that provides compact logic and timing for small automation tasks. It offers 20 I/O with a 24 V DC supply and includes an integrated clock and display for on-board timing, status readouts, and quick diagnostics. The unit includes eight relay outputs to switch loads such as sensors, actuators, lights, or small motors, reducing wiring and panel space in automation projects. Programmable with Zelio Soft 2, it supports simple ladder logic or function block diagrams to implement timing, logic, and input/output sequencing—ideal for machine panels, small conveyors, or HVAC control that requires a compact, self-contained logic solution. Its plug-in, DIN-rail friendly design simplifies panel design and commissioning for OEMs and integrators seeking a compact Zelio smart relay solution.
