- Description
The Schneider Electric SR3XT141BD is a discrete I/O extension module for the Zelio Logic SR3 range, adding 14 I/O (8 discrete inputs, 6 relay outputs) at 24 V DC to a base smart relay. It mounts on the same DIN rail as the base unit to expand the I/O count of larger automation systems.

Selection Notes
The SR3XT141BD adds 8 discrete inputs and 6 relay outputs to a 24 V DC Zelio Logic base unit, sitting between the smaller SR3XT61BD (4 in / 2 out) and the larger SR3XT101BD (6 in / 4 out) for machines that need a mid-size I/O boost. Two of its six outputs are current-limited to 5 A while the other four carry 8 A — route higher-current loads to the 8 A-rated points.
