Product Overview
The Schneider Electric SR2B121FU is a
Zelio Logic compact smart relay with
12 I/O points: eight 100–240 V AC discrete inputs and
four normally open relay outputs. It operates from a
100–240 V AC, 50/60 Hz supply and provides a
built-in real-time clock and local display.
Ladder and FBD programming support compact machine and building control
functions. Relay output loading must follow Schneider's rated load
category limits; confirm voltage, wiring and installation before ordering.
