Zelio LogicSchneider Electric SR3XT61FU Zelio Logic SR3 6 I/O Extension Module 100-240 V AC PLC I/O Module
Schneider Electric SR3XT61FU Zelio Logic SR3 I/O extension module, 6 I/O, 100-240 V AC, 2 relay outputs.
Description
About the SR3XT61FU
About the SR3XT61FU
The Schneider Electric SR3XT61FU is a discrete I/O extension module for the Zelio Logic SR3 range, adding 6 I/O (4 discrete inputs, 2 relay outputs) at 100–240 V AC to a base smart relay. It mounts on the same DIN rail as the base unit for a small additional I/O count without a separate 24 V DC supply.

Selection Notes
The SR3XT61FU is the smallest AC-supplied Zelio Logic SR3 extension module, adding 4 discrete inputs and 2 relay outputs (8 A each) directly from 100–240 V AC — use it instead of the DC-supplied SR3XT61BD when the panel has no 24 V DC rail. Step up to the SR3XT141FU when more than 4 extra inputs or 2 extra outputs are needed.
