Schneider Electric Zelio Logic SR3B101FU Smart Relay (100...240V AC, 6 Inputs / 4 Outputs)

Schneider Electric Zelio Logic SR3B101FU Smart Relay (100...240V AC, 6 Inputs / 4 Outputs)

Product Description: The Schneider Electric Zelio Logic programmable smart relay (model SR3B101FU, branded under Telemecanique) is designed for the automation of small control systems and localized industrial processes. This compact module serves as a highly efficient and cost-effective alternative to traditional PLCs in applications where ease of programming, flexibility, and high reliability are essential. The relay features an integrated backlit liquid crystal display (LCD) and navigation buttons, allowing users to configure parameters, monitor input/output statuses, and adjust logic directly on-site. Additionally, the built-in real-time clock (RTC) enables precise automation based on time, schedule, and calendar events.

Application: This smart relay is widely used in the automation of building management systems, residential utilities, and small-scale industrial applications. It is commonly implemented for controlling lighting networks (facade, landscape, or scheduled internal lighting), HVAC systems (ventilation and air conditioning), pumping groups (water supply, drainage), automatic irrigation systems, and motorized gates or shutters. It is also well-suited for small machinery like conveyors or mixers, and automatic transfer switch (ATS/АВР) control panels.
