Active production — what that means for your BOM line
The 3RA2831-2DG10: The adjustable time range spans 0.05 to 100 s, with a recovery time of 50 ms between cycles. That covers most start-delay and sequencing applications in motor control — pump lead-lag, conveyor staging, compressor unload timing.
Control voltage and mounting — no surprises
Accepts 24 to 90 V AC/DC on the control supply — works across 24 VDC control systems and 48-90 VAC pilot circuits common in North American and European panels. The module snaps onto the contactor via clip-on fastening; no DIN rail slot consumed, no extra wiring terminals. Storage and transport range extends to -40 to +85 °C. Pollution degree 3 with basic insulation — suitable for standard industrial control panels without special derating.
Dimensions and panel fit
The module measures 45 mm wide, 38 mm high, 74 mm deep — it adds about 45 mm to the contactor width when clipped on the side. The zero-clearance mounting clearances (0 mm upwards, downwards, forwards, backwards, and sideways) mean it can sit tight against panel walls or adjacent components without derating. Wire termination accepts solid or stranded 20-14 AWG (2x conductors per terminal). The AWG range covers standard motor control wiring — 14 AWG for control power runs, 18 AWG for signal wiring.
