Schneider Electric SR3B261BD Zelio Logic SR3 26 I/O 24 V DC Display Relay Output Logic Module

The Schneider Electric SR3B261BD is a Zelio Logic SR3 modular smart relay with 26 I/O (16 discrete inputs, 6 analogue-capable, 10 relay outputs), a 24 V DC supply and a backlit LCD display with navigation buttons. It is a compact programmable controller for managing, monitoring and remote-controlling larger automation systems in industrial and commercial installations.

Selection Notes

The SR3B261BD steps up to 26 I/O (16 discrete, 6 analogue, 10 relay outputs) versus the 10 I/O SR3B101BD, so it fits larger stand-alone machines that would otherwise need an extension module on the smaller base. Two of its ten relay outputs are current-limited to 5 A while the other eight carry 8 A — route higher-current loads to the 8 A-rated points. Where the load needs faster, protected DC switching instead of relay contacts, the transistor-output SR3B262BD is the equivalent 26 I/O variant.
