Overview

The 140CRA31908 is an Ethernet RIO drop adaptor in the Modicon Quantum range from Schneider Electric. It extends Modicon Quantum connectivity through its onboard communication interface.

Application & Technical Notes

As an ethernet rio drop adaptor, the 140CRA31908 is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It bridges the controller to higher-level networks, HMIs, SCADA and peer devices, carrying configuration, process data and diagnostics.

Key published characteristics include an operating temperature range of 32…140 °F (0…60 °C) IEC 60068-2-2. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.

Maintenance & Diagnostics

Respect the published operating temperature window (32…140 °F (0…60 °C) IEC 60068-2-2); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -40…185 °F (-40…85 °C) IEC 60068-2-2. Avoid condensation — the rated humidity is 93 % conforming to IEC 60068; store and operate the module in a dry, pollution-degree-appropriate enclosure. Confirm network addressing, baud/rate and topology match the rest of the system; keep firmware consistent across the cell. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the 140CRA31908, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Match the protocol, connector and topology to the rest of the Modicon Quantum network and to the peer devices already installed. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
