What this Ethernet module does in a Quantum rack
The 140NWM10000 is a class D10 Ethernet TCP/IP module for the Modicon Quantum automation platform, providing Modbus TCP/IP communication and embedded web services including a rack viewer and FactoryCast HMI. It draws 750 mA from the 5 V DC rack backplane and supports 10/100 Mbit/s transmission over either an RJ45 twisted-pair or an MT/RJ fiber optic interface.
Lifecycle status and sourcing reality
Availability is limited to independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ against your BOM line.
Key specs that govern fit
The module uses the standard Quantum form factor and draws power from the rack backplane — no separate supply needed. The IP20 rating means it belongs in a protected enclosure, not on an open panel face. It carries FM Class 1 Division 2 and CSA C22.2 No 142 approvals, so it is rated for installation in hazardous locations where flammable gases or vapors are not normally present. The operating temperature range is 32 to 140 °F (0 to 60 °C) with 95 % relative humidity non-condensing, and it is rated for altitudes up to 4500 m.
