Product Details
Product Overview
The Allen Bradley 1747-DTAM provides a direct, cost-effective interface for accessing and modifying data tables within the SLC 500 processor. This Data Table Access Module allows plant floor personnel to monitor timer/counter values, change setpoints, and view bit status without a full-scale HMI or programming laptop. Despite the manufacturer’s discontinuation of this series, we offer this unit as 100% Brand New original factory stock. This ensures your legacy control systems remain operational with authentic, high-integrity hardware that meets original performance specifications.

Engineering Advantages
-
Real-Time Process Transparency: The backlit LCD displays two lines of high-contrast text, allowing operators to monitor critical process variables in poorly lit industrial environments. It provides immediate access to the SLC 500 data files (Binary, Integer, Timer, Counter), which accelerates localized troubleshooting.
-
Zero-Maintenance Power Management: The 1747-DTAM draws its 24V DC power directly from the SLC 500 CPU via the communication cable. This eliminates the need for external power supplies or complex cabinet wiring, simplifying installation in cramped control panels.
-
Rugged Tactile Interface: The module utilizes industrial-grade membrane keys that resist common shop-floor contaminants like oil and dust. This design ensures responsive input for setpoint adjustments, solving the pain point of using delicate touchscreen interfaces in harsh environments.
-
Legacy Hardware Stabilization: Replacing a failed interface with our 100% Brand New stock prevents the compatibility issues often found with refurbished or third-party alternatives. This unit restores original tactile feel and display clarity to your control station immediately.
FAQs
-
Do I need an external power supply for the 1747-DTAM?
No. The module receives all necessary 24V DC operating power directly from the SLC 500 processor through the 1747-C10 connection cable. Ensure the CPU has sufficient power capacity for the module's draw.
-
Is the 1747-C10 cable included with the module?
No. The 1747-DTAM requires the 1747-C10 cable for operation, which you must purchase separately. This cable facilitates both data communication and power delivery between the processor and the interface.
-
Can the 1747-DTAM modify logic or just view data?
The module primarily allows users to monitor and modify data table values (setpoints, presets, etc.). It does not allow for the modification of ladder logic rungs; for logic changes, you still require RSLogix 500 software.
-
How do I confirm this unit is truly brand new?
Every 1747-DTAM we ship arrives in its original factory-sealed Allen Bradley packaging. We guarantee that the unit has never been installed, energized, or refurbished, providing the maximum possible service life for your legacy system.

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
