Single-port Ethernet interface for the Modicon M340 rack — the BMXNOE0100 draws 90 mA from the 24 VDC backplane and occupies one standard-module slot. The supplied Flash memory card (BMXRWSC016M) enables the embedded web server and application saving. Port is 10BASE-T/100BASE-TX RJ45, Transparent Ready class B30.
Compared to the BMXNOC0401
The BMXNOC0401 is the four-port brother in the M340 Ethernet family — it adds an embedded 4-port switch with RSTP and port mirroring, plus hazardous-location and IEC 61850 ratings. But the power rail is different: the BMXNOE0100 runs on 24 VDC (90 mA), while the BMXNOC0401 draws 555 mA from the 3.3 VDC rail. Both use the same rack internal supply, so swapping them means checking the backplane's current budget at both voltages. Form factor and rack connection are identical, but network topology and power planning differ.
IP20, standard M340 slot. Status LEDs on the face: RUN, ETH ACT, ETH STS, ETH 100, CARD ERR, ERR. Ambient operating range 0–60 °C, humidity 10–95% non-condensing. Conformal coating (TC) for mild environmental protection. No field wiring beyond a standard RJ45 patch cable; the module is entirely backplane-powered.
