Schneider Electric SR3B102BD Zelio Logic SR3 10 I/O 24 V DC Display Transistor Output Logic Module

The Schneider Electric SR3B102BD is a Zelio Logic SR3 modular smart relay with 10 I/O (6 discrete inputs, 4 analogue-capable, 4 transistor 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 simple automation systems in industrial and commercial installations.

Selection Notes

The SR3B102BD's transistor outputs switch in ≤ 1 ms with built-in overload, short-circuit and overvoltage protection, which suits fast, high-cycle 24 V DC loads such as solenoids or indicator circuits better than the relay-output SR3B101BD (10 ms typical, no electronic protection but up to 8 A per output and AC-load capable). Because the transistor stage is limited to 0.5–0.625 A per point and 24 V DC, use SR3B101BD instead when the load needs AC switching or a higher current per point.
