The Schneider Electric SR2A201BD is a compact smart relay in the Zelio Logic product family. It is designed to simplify control tasks that would otherwise require conventional relay wiring or a more extensive programmable controller.
This model combines a 24 V DC power supply, 12 discrete inputs, 2 analog inputs, and 8 relay outputs. Its integrated display provides convenient local access, while its programmable logic functions allow users to configure control sequences for small machines and auxiliary equipment.
The SR2A201BD is supplied without a real-time clock, making it important to distinguish it from other Zelio Logic models when selecting equipment for time-dependent applications. For maintenance teams and system integrators, it offers a compact control solution for straightforward automation projects and equipment upgrades.
