The SR3XT141BD is a plug-in smart relay module from Schneider Electric's Harmony (Zelio Logic) SR3 series. It is designed as a remote or distributed I/O head that connects to a central SR3 smart relay base unit (like the SR3DRC5 or SR3DRM5) via a bus cable.
Specifications:
Parameter Specification
Product Range Harmony / Zelio Logic (Smart Relays - SR3 Series Expansion)
Device Type Plug-in Remote I/O Expansion Module (for SR3 Smart Relay)
Compatible Main Unit Must be connected to a main SR3 smart relay with expansion bus capability (e.g., SR3DRC5, SR3DRM5) via a dedicated bus cable.
Power Supply 24V DC (Supplied locally to the expansion module or via the bus, depending on configuration).
Digital Inputs 8 inputs (Typically 24V DC, sink/source compatible).
Relay Outputs 2 outputs (Relay contacts, SPDT/changeover type).
Output Contact Rating Typically 8 A @ 250V AC (resistive load).
Expansion Method Connects to the main unit via a dedicated expansion bus cable. Multiple XT modules can be daisy-chained.
Internal Logic No independent logic capability. It is purely an I/O extension. All programming and logic processing is done in the main SR3 smart relay unit.
Status Indication LEDs for power and I/O status.
Mounting DIN Rail (35mm)
Operating Temperature -20°C to +55°C (typical)
Standards & Approvals UL 508, CSA, IEC/EN 61131-2, CE, RoHS.
