140CRP93100

The 140CRP93100 is a Remote I/O (RIO) head-end adaptor module built for the Modicon Quantum automation platform, compatible with the Quantum 200, 500, and 800 series as well as Symax systems in any mix. It serves as the central communication bridge between the Quantum PLC CPU and distributed remote I/O drops, using a single female coaxial connector and 75-ohm coaxial cabling to support up to 31 drops per network. With a high-speed transmission rate of 1,544 Mbit/s and a dynamic range of 35 dB, it delivers fast, reliable data exchange across demanding industrial environments.140CRP93100

This unit has been fully tested and verified to meet original factory performance standards. Each module undergoes a thorough inspection process to confirm proper operation of onboard diagnostics — including power-up checks, memory verification, and LAN controller validation — giving buyers confidence in its real-world readiness. The coaxial isolation voltage of 500 V DC between the center conductor and ground ensures robust electrical protection in harsh plant environments.140CRP93100

Designed for continuous industrial duty, the module operates reliably across an ambient temperature range of 0°C to 60°C, with storage tolerance from -40°C to 85°C and relative humidity up to 95% non-condensing. Its low power draw — just 3 W dissipation and 600 mA bus current — minimizes thermal loading on the Quantum backplane. FM Class 1 Division 2 certification and compliance with UL 508, CUL, and CSA C22.2 No. 142 further underscore its suitability for hazardous and safety-critical locations.140CRP93100

Buying a used and tested part number 140CRP93100 is a cost-effective way to maintain or expand an existing Quantum RIO network without the lead times associated with new procurement — particularly important given that this module reached end-of-life status in March 2022 and is no longer manufactured. Whether you are replacing a failed unit or building out spare inventory, this tested module offers a dependable, drop-in solution for facilities running legacy Quantum automation infrastructure.

RIO Head-End Role: This module acts as the primary interface between the Quantum PLC and up to 31 remote I/O drops over a single coaxial cable connection.
High-Speed Data Link: A transmission rate of 1,544 Mbit/s enables fast, low-latency communication across the distributed I/O network.
Broad Compatibility: Works seamlessly with Quantum 200, 500, and 800 series controllers as well as Symax systems in any mix configuration.
Startup Diagnostics: Built-in diagnostics automatically check power, memory, and the LAN controller at startup to help identify faults quickly.
Hazardous Location Rated: FM Class 1 Division 2 certification means the module is approved for use in industrial environments with potentially explosive atmospheres.
