Product Overview
The Schneider Electric SR3B261FU is a
Zelio Logic SR3 modular smart relay featuring
26 digital I/O points: 16 AC digital inputs
and 10 normally open relay outputs. It operates from a
100–240 V AC supply and includes an
integrated clock and local display. Its relay outputs
have different thermal-current ratings: 8 outputs at 8 A
and 2 outputs at 5 A, subject to load category.
It supports Ladder Logic and FBD programming and
model-specific Zelio Logic SR3 I/O extensions. Installation is possible
on a 35 mm DIN rail or by screw fixing.
Confirm the exact model, AC input wiring, contact loading, software
requirements and compatible expansion modules before ordering.
