Schneider Electric SR3B261FUXT141FU Logic Relay

Schneider Electric SR3B261FUXT141FU is a Zelio Logic modular smart relay configuration that combines the base SR3B261FU with the SR3XT141FU expansion module to deliver scalable I/O for compact automation projects, enabling you to tailor input/output counts to the needs of a given machine or control panel and to configure the system around a single 100–240 V AC supply. The base SR3B261FU provides 26 I/O on a 100–240 V AC supply, consisting of 16 discrete inputs and 10 relay outputs, and it integrates a clock and display to show timing and status directly on the unit. The SR3XT141FU expansion module adds 14 I/O to the Zelio Logic SR3 family and is rated for 100–240 V AC, allowing you to extend input/output capacity while maintaining a single power supply for the system and keeping wiring straightforward. As part of Schneider Electric's Zelio Logic SR3 family, this configuration offers a compact, modular approach to discrete input/output control for small automation tasks, enabling straightforward expansion for increased sensing and switching needs.
