Schneider Modicon Quantum 140DRA84000 16-Channel Relay Discrete Output Module

Product Overview

The Schneider Electric 140DRA84000 provides versatile power switching capabilities for the Modicon Quantum automation platform. This module features 16 independent Normally Open (1 NO) Form A relay contacts, allowing the PLC to control a wide range of AC and DC field devices. It bridges the gap between low-level logic and high-power actuators like motor starters, interposing relays, and solenoid valves. We supply this module as 100% Brand New and Original, ensuring optimal contact surface integrity and mechanical reliability for your high-availability control systems.

Technical Specifications

The 140DRA84000 manages diverse voltage ranges and load types with high electrical durability.

Engineering Advantages

• Multi-Voltage Switching Versatility: One 140DRA84000 module simultaneously controls AC and DC loads across a massive voltage spectrum ($5$ V DC to $250$ V AC). This flexibility eliminates the need for separate DC and AC output cards in hybrid control environments.

• Superior Isolation Barriers: The module provides $1780$ Vrms isolation between individual channels and between the channels and the backplane bus. This prevents field-side electrical noise and transient surges from migrating into the sensitive PLC processor electronics.

• Integrated Surge Suppression: Built-in $275$ V varistors protect the internal relay contacts from inductive kickback and overvoltage spikes. This internal protection significantly extends the electrical life of the module and reduces the need for external snubbers.

• High-Current Handling: Each relay supports up to $2$ A resistive loads at $60$ °C. This allows the module to drive many medium-sized industrial actuators directly, reducing the cost and cabinet space required for external interposing relays.

• Advanced Visual Feedback: 16 dedicated green LEDs provide immediate status for each output point. A separate red "Fault" LED and a green "Active" LED allow maintenance teams to verify bus communication and identify external fault conditions at a glance.

FAQs

• Does the 140DRA84000 require an external power supply for the relays?

  The module draws $1100$ mA from the Quantum backplane to energize the relay coils. However, you must provide the external power source ($20-250$ V AC or $5-150$ V DC) for the loads you intend to switch through the contacts.

• Can I mix AC and DC loads on the same module?

  Yes. Because the 140DRA84000 features isolated relay contacts, you can wire different voltage sources to different channels. Ensure you maintain proper wiring separation and adhere to the $1780$ Vrms isolation limits between channels.

• What is the difference between "Mechanical" and "Electrical" durability?

  Mechanical durability ($10$ million cycles) represents the life of the relay without a load. Electrical durability ($100,000$ to $200,000$ cycles) indicates the expected life when switching rated current. Switching high-inductive loads without external suppression will reduce electrical durability.

• What terminal block should I use for wiring?

  The module requires the standard Modicon Quantum 40-pin screw terminal block, model 140XTS00200. We recommend using the correct wire gauge (up to 14 AWG) to handle the $2$ A maximum load per channel.
