100-DNY42R | Allen-Bradley | DeviceLogix 24V DC Digital I/O Combination Module

Product Overview

The Allen-Bradley 100-DNY42R operates as a high-performance DeviceLogix™ combination I/O module, designed to decentralize logic processing in motor control applications. This module provides 4 digital inputs and 2 digital outputs, allowing for autonomous local control even if the master PLC communication fails. While the manufacturer has officially discontinued this series, we provide 100% Brand New and original units from our secure inventory to support your legacy system maintenance and expansion needs.

Technical Specifications

The 100-DNY42R integrates directly into motor starters and smart contractors to execute fast-acting local logic.

Engineering Advantages

• Localized Logic Processing: The integrated DeviceLogix technology executes Boolean logic commands internally. This capability reduces the response time for critical interlocking and local control tasks by bypassing the network latency associated with a central PLC scan.

• Network Failure Protection: In the event of a DeviceNet or ControlNet communication loss, the 100-DNY42R maintains its programmed state or executes a pre-defined safety routine. This "Smart" functionality prevents uncontrolled machine behavior during network dropouts.

• Space-Saving Integration: The module attaches directly as an accessory to the host motor starter or contactor. This eliminates the need for additional DIN rail space and complex inter-cabinet wiring for basic I/O points.

• Reduced Master Controller Load: By handling local sensor inputs (e.g., limit switches or proximity sensors) at the device level, the 100-DNY42R reduces the data traffic on the main industrial network, optimizing overall system bandwidth.

• Simplified Commissioning: Using standard RSNetWorx for DeviceNet, engineers configure the local logic through a simple drag-and-drop interface, making field adjustments straightforward and efficient.

FAQs

• How can this module be "Brand New" if the manufacturer discontinued it?

  We maintain a specialized inventory of factory-sealed, never-used hardware. Although Allen-Bradley no longer produces the 100-DNY42R, our stock consists of 100% Brand New, original units intended for critical infrastructure support.

• Does this module require a specific software for configuration?

  Yes. You typically configure the DeviceLogix logic using RSNetWorx for DeviceNet. The software allows you to program the 4 inputs and 2 outputs using a function block editor.

• Can the 100-DNY42R replace a standard auxiliary contact block?

  While it occupies a similar physical space, this is a smart module. It provides much higher functionality than a passive contact by allowing you to program logic, making it ideal for distributed automation rather than simple signaling.

• What is the primary application for this module?

  It excels in distributed motor control where local sensors must trigger immediate contactor action, such as conveyor jam detection or local pump start/stop sequences.
