Product Summary
Engineers use the 1734-8CFGDLX for distributed control applications requiring local logic. This 8-point module operates on a 24 Volts DC supply. Each channel can flexibly function as either a digital input or output. The integrated DeviceLogix technology processes data without a central controller. This design reduces system wiring and improves overall response times. It is an ideal solution for modern, decentralized automation architectures.
Expert Guide: Procurement & Technical Selection for the 1734-8CFGDLX
Selecting the correct I/O module demands a clear understanding of the specific application needs. The 1734-8CFGDLX provides unique flexibility that supports complex machine designs.
Smart Automation with DeviceLogix
This module incorporates Rockwell Automation's DeviceLogix Smart Component Technology. This feature enables onboard logic solving for local control tasks. Users can program the module to read inputs and control outputs directly. This greatly reduces dependency on a master PLC or network scanner. The result is faster machine responses and lower total system costs.
Configurable Channel Architecture
Each of the 8 I/O points on the 1734-8CFGDLX can be independently set. You can configure a channel as a 24V DC input or a DC output. This adaptability simplifies inventory management and reduces spare parts needs. The module supports a minimum operational voltage of 11 Volts DC. It delivers an on-state input current between 2.0 and 5.0 milliamps.
Operational Modes for Network Flexibility
The 1734-8CFGDLX operates in three distinct modes for maximum system integration. First, it works as a standard I/O module on ControlNet, DeviceNet, or EtherNet/IP networks. Second, with DeviceLogix enabled, it functions as a standalone controller. Third, peer-to-peer mode uses the “Auto Produce” parameter to share data. This eliminates the need for a central master unit in simple systems.
Environmental and Mechanical Specifications
This module mounts directly onto a standard DIN rail for secure industrial installation. It operates reliably within a temperature range of -20 to 55 degrees Celsius. The unit has an open-style enclosure suitable for controlled cabinet environments. Its power dissipation is rated at a maximum of 2.6 Watts. This keeps thermal output low at 8.9 BTU/hour.
Practical Installation Guide for the 1734-8CFGDLX Module
Proper installation ensures reliable operation and long service life for the 1734-8CFGDLX. Follow these steps for a safe and efficient deployment.
Compatible Terminal Bases
The 1734-8CFGDLX works with several POINT I/O terminal base units. These include the 1734-TOP, 1734-TOPS, 1734-TB, and 1734-TBS models. You can install the module either before or after mounting the base. This flexibility allows for easier system assembly and maintenance.
Electrical Configuration and Data Handling
This module communicates through the POINTBus backplane. It requires 100 mA of current at 5 Volts DC from the bus. During operation, it produces 20 bytes of data for the control system. Each input channel has an independently settable filter time. The default filter time is set to 1000 milliseconds. Adjust this value in millisecond intervals to match sensor characteristics.
Network and Compliance Standards
When used as a standard I/O device, the module uses ODVA assemblies. It adheres to the “produce” and “consume” data exchange protocols. The module supports hot-swapping under power with auto-address and auto-baud features. This maintains high system uptime during maintenance or reconfiguration tasks.
