140DRC83000 | Schneider Electric | Modicon Quantum 8-Channel Relay Output Module

Product Overview

The 140DRC83000 provides flexible discrete control within the Schneider Electric Modicon Quantum platform. This module features 8 high-performance relay outputs utilizing Form C (1 NO/NC) contact arrangements. It bridges the gap between low-level PLC logic and high-power field devices, supporting voltages up to 250V AC or 150V DC. We supply this module as 100% Brand New and Original, ensuring peak mechanical and electrical durability for critical infrastructure.

Technical Specifications

The 140DRC83000 supports diverse load types, ranging from resistive to highly inductive capacitive loads:

Engineering Advantages

• Form C Versatility: Unlike standard NO-only modules, the Form C architecture provides both Normally Open and Normally Closed contacts for every point. This allows engineers to implement fail-safe hardwiring and interlock logic directly at the module level.

• Extreme Isolation Safeguards: The module provides 1780 Vrms AC isolation between individual channels and the backplane bus. This prevents field-side electrical surges from damaging the expensive Quantum processor or neighboring I/O modules.

• Inductive Load Resilience: Integrated varistors (275 V) suppress transient overvoltages. This feature significantly extends contact life when switching inductive loads like solenoids or small motor starters, reaching up to 100,000 electrical cycles even under heavy DC resistive loads.

• Comprehensive Diagnostics: Ten front-facing LEDs provide real-time status. A green LED monitors bus communication (Active), a red LED signals detected external faults (F), and eight individual green LEDs track the state of every input point, accelerating onsite troubleshooting.

• Marine & Hazardous Duty Ready: With certifications including ABS, DNV, RINA, and FM Class 1 Division 2, this module operates reliably in maritime environments and explosive atmospheres where standard I/O hardware might fail.

FAQs

• Can I use the 140DRC83000 to control tungsten lighting?

  Yes. The module supports a 2 A load at 250/30 V AC/DC for tungsten applications (1/4 hp, cos phi = 0.4). For standard resistive loads, the capacity increases to 5 A.

• What is the difference between this and a standard DC output module?

  This is a mechanical relay module. It provides "dry contacts" and handles significantly higher current (5 A) compared to solid-state DC modules, and it accommodates both AC and DC voltages on the same module.

• Does this module require external surge protection?

  The module includes internal varistor protection rated at 275 V. However, for highly inductive loads with fast switching frequencies, we recommend adding external snubbers or diodes to further prolong the 100,000-cycle electrical lifespan.

• Is this product a current factory model?

  Yes, we supply this as 100% Brand New stock in original Schneider Electric packaging. It serves as a direct replacement or expansion for any existing Modicon Quantum system.
