The Schneider Electric A9XMC1D3 is a PowerTag Control input/output module — a compact, clip-on DIN-rail slice that adds one dry-contact sense point and one programmable relay output to an Acti9 PowerTag energy-monitoring network. It lives in the same 18 mm wide footprint as the rest of the PowerTag family, so it slots into an existing PowerTag Link concentrator chain without extra panel real estate. The single digital input is rated for dry contacts at 230 V AC, 2 mA, and the output is a configurable NO/NC relay rated 230 V AC, 0.01 to 2 A. That output rating means it switches small pilot-duty loads — indicator lamps, contactor coils, signal lamps — not motor loads directly. The 100,000-cycle mechanical durability is typical for a signal relay; plan for it in a control scheme, not a high-cycle power-switching role. The IP20 casing and IP40 front face are standard for a dry indoor enclosure; no washdown rating here.
Wiring and integration
The module occupies two 9 mm pitches, so 18 mm of rail width. Tunnel-type terminals: top connection accepts 1 to 16 mm² rigid, bottom accepts 1 to 6 mm² rigid. Wire stripping lengths are 14 mm for the top (power supply) and 9 mm for the bottom (I/O). Tightening torque: 2 N·m for the top power terminals, 1 N·m for the bottom I/O terminals. The input is a dry-contact type at 230 V AC, 2 mA. State 0 guaranteed at ≤ 0.5 mA, state 1 at ≥ 2 mA — so a standard pushbutton or limit switch with a 2 mA wetting current will be read reliably. The output is a relay with NO/NC programmable logic, configurable through the PowerTag Link concentrator.
