Schneider Modicon 140CRA93200 Quantum RIO Drop Adapter

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. The Schneider Modicon 140CRA93200 Remote I/O Drop Adapter Module connects remote Quantum I/O backplanes to the primary PLC processor rack over the S908 coaxial network, enabling high-speed distributed control across large manufacturing environments.

From a Total Cost of Ownership (TCO) perspective, holding a verified New Surplus 140CRA93200 module in local safety stock is a vital safeguard against extended line outages. Because Schneider Electric has phased out legacy S908 Quantum components, a failed drop adapter halts all communication to an entire remote I/O rack, causing total shutdown of connected field instrumentation. Maintaining 1 unit as on-site buffer stock eliminates long lead time variability and avoids the corrupt communication logic, worn BNC connectors, and signal attenuation common in cheap refurbished units.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Execute Lock-Out/Tag-Out (LOTO) procedures on the power supply module powering the remote Quantum rack.
2. Put on a grounded anti-static wrist strap attached to the metal enclosure frame.
3. Note the exact positions of the two rotary address switches (TENS and UNITS) on the side or rear of the module being replaced.

Stage 2: Removal

1. Unplug the dual BNC coaxial network cables from Ports A and B by twisting the bayonet locks counter-clockwise.
2. Depress the top and bottom module release levers on the Quantum backplane slot.
3. Pivot the module forward, lift it off the lower backplane mounting rail, and place it directly inside an ESD-shielded bag.

Stage 3: Installation (Clone & Seat)

1. Set the rotary address switches on the new 140CRA93200 module to match the assigned RIO Drop Number (1 to 63) of the original unit.
2. Hook the lower rear notch of the drop adapter module onto the Quantum backplane rail in slot 1 or 2 of the remote rack.
3. Pivot the module upward and press firmly until both top and bottom latches click flush into place. Reconnect the BNC coaxial network cables to Ports A and B.

Stage 4: Power-On & Testing

1. Re-energize the remote Quantum backplane power supply.
2. Observe the front-panel LEDs; confirm the READY and RUN LEDs illuminate solid green, and the COMM light indicates active data transfer.
3. Verify at the master CPU programming console that all remote I/O points associated with this drop address report healthy status without communication error bits.

Firmware/Software Versions & Upgrade Notes

• Software Compatibility: Fully supported across Concept, ProWORX 32, and EcoStruxure Control Expert environments.
• Hardware Revision: Executable Hardware Rev 01 or later.
• Firmware Swap Warning: The 140CRA93200 acts as a hardware bridge that mirrors I/O configuration table data pushed from the main CPU head module (e.g., 140NOA61100 or 140CPUxxxx). Ensure the rotary drop address is set correctly before applying power; an incorrect drop address will cause a network conflict and force the drop adapter into a communication timeout fault state (ERR LED flashing).

Frequently Asked Questions (FAQ)

Is this Schneider Modicon 140CRA93200 module 100% Genuine New Surplus?

Yes. This drop adapter is 100% Genuine New Surplus. It has never seen active duty in an industrial facility and was sourced from clean spare parts inventory. We enforce a strict zero-tolerance policy against second-hand, pulled, or refurbished components.

Why pay more for New Surplus instead of a cheaper refurbished 140CRA93200 module?

Refurbished communication modules often suffer from degraded BNC connector joints, aged line isolation transformers, or latent ESD damage that causes intermittent packet loss across the S908 coaxial bus. Investing in New Surplus guarantees factory-clean signal paths, tight physical connections, and maximum network immunity.

What is the OEM lifecycle status for the Modicon 140CRA93200?

The 140CRA93200 is an obsolete part as Schneider Electric has transitioned users from legacy coaxial S908 networks to Ethernet-based Modicon M580 platforms. Sourcing New Surplus units allows facility managers to maintain active Quantum remote drop racks reliably without undertaking immediate, expensive cable re-wiring and PLC migrations.

Can I hot-swap this remote drop adapter while the remote rack is running?

Modicon Quantum backplanes support Removal and Insertion Under Power (RIOC). However, removing the 140CRA93200 while the remote rack is active will immediately freeze all local I/O outputs at their last state or default safety values. Always put the local system in a safe state before pulling the drop adapter.

What warranty coverage comes with this part?

Unlike standard 30-day warranties typical for used surplus parts, our New Surplus 140CRA93200 module includes a full 1-year functional replacement warranty backed by complete static and power-on QC testing.
