Product Overview
The Allen-Bradley 1734-8CFGDLX is an 8-point configurable I/O module from the POINT I/O series. It combines digital input and output functionality in a single unit, rated for 24 Volts DC. Each point can be independently configured as either an input or an output, offering exceptional flexibility for distributed control architectures. With built-in DeviceLogix Smart Component Technology, this module provides local logic-solving capability, reducing dependency on a central controller and enhancing system responsiveness.

Key Features & Benefits
-
DeviceLogix Integration: The 1734-8CFGDLX supports DeviceLogix, enabling local control logic that improves performance and reduces cost.
-
Configurable I/O: Each of the 8 points can be set as a DC input or output, adapting to various application needs.
-
Hot Swap Capability: Compliant with POINTBus backplane, allowing module removal and insertion under power with auto-addressing and auto-baud.
-
Multiple Operating Modes: Works as a standard I/O module using ODVA assemblies, as a standalone DeviceLogix unit, or as a peer-to-peer module with Auto Produce.
-
Flexible Mounting: DIN rail mountable and compatible with 1734-TOP, 1734-TOPS, 1734-TB, and 1734-TBS terminal bases.
-
Low Power Consumption: Power dissipation max 2.6 W; thermal dissipation 8.9 BTU/hour at 28.8 V DC.
Industry Applications
The Allen-Bradley 1734-8CFGDLX is ideal for applications requiring distributed I/O with local intelligence. Common uses include:
- Material handling systems where fast, local decision-making reduces conveyor downtime.
- Packaging machinery that benefits from configurable I/O to handle various sensor and actuator signals.
- Process control panels where space is limited and modularity is essential.
By integrating DeviceLogix, the 1734-8CFGDLX can execute simple logic without a master controller, improving response times and reducing network traffic.
Installation & Setup
Mount the 1734-8CFGDLX onto a DIN rail and attach it to a compatible terminal base (1734-TOP, 1734-TOPS, 1734-TB, or 1734-TBS). The module can be installed either before or after wiring the base. Ensure proper grounding and follow POINTBus backplane guidelines for hot-swapping. Configure each I/O point using the appropriate software, setting input/output direction and filter times as needed.
Maintenance & Reliability
Routine inspection of the module and terminal connections is recommended to ensure reliable operation. The open enclosure design allows for heat dissipation, but keep the area free of dust and debris. Operating temperature range is -20 to 55°C; avoid exceeding these limits. The 1734-8CFGDLX's low power dissipation reduces thermal stress, extending service life.
Compatibility & Integration
The 1734-8CFGDLX is part of the POINT I/O family and communicates over the POINTBus backplane. It supports standard ODVA produce/consume assemblies and can operate on ControlNet, DeviceNet, or EtherNet/IP networks when used with appropriate adapters. Its DeviceLogix capability allows standalone or peer-to-peer operation, making it versatile for various control architectures.
Selection Guide
Before purchasing, verify that your system's backplane and power supply meet the module's requirements (POINTBus current 100 mA at 5 V DC). Ensure the operating environment stays within the specified temperature range. For genuine Allen-Bradley 1734-8CFGDLX modules and expert support, choose PLC Source PRO as your trusted supplier.
