Identification and key ratings
Schneider Modicon Quantum 140CRA93100C RIO drop adaptor module for Ethernet/IP-controlled drops. 1544 Mbit/s over 75 Ohm coax F-connector, 500 V DC isolation.
Lifecycle status and sourcing reality
Officially obsolete; the Schneider description notes a last-time-buy window that has now passed, and no direct-replacement order code is listed.
Environmental and operational limits
Rated for 0 to 60 °C operating ambient, storage from -40 to 85 °C, and 95 % relative humidity without condensation. Altitude tolerance to 5000 m. Conformal coating (Humiseal 1A33) is applied as standard. Power dissipation is 3 W per channel; bus current draw is 600 mA. Diagnostics cover power-up and runtime checks: RAM address/data integrity and executive checksum. Electrical fast transient and electrostatic discharge immunity meet IEC 801-2 levels (4 kV contact, 8 kV air) and IEC 801-3 for radiated fields (9.1 V/m at 80–1000 MHz).
Certification and standards compliance
Listed under CSA C22.2 No 142 and CUL UL 508, suitable for North American industrial control panels. No RoHS or REACH declaration appears on the record; verify with your local quality or compliance team if material restriction data is required for your plant.
