Description
Product Name: 1747-DTAM Allen Braley Central control module
Product details:
The Allen-Bradley 1747-DTAM (Data Table Access Module) is a classic operator interface device designed specifically for the SLC 500 programmable controller family. It provides a convenient way for plant floor operators to monitor and manipulate data without needing a full programming terminal.
1. Product Description
The 1747-DTAM serves as a compact, panel-mounted interface. It allows users to interact directly with the SLC 500 processor’s data tables. It features a monochrome LCD display and a sealed membrane keypad, making it suitable for harsh industrial environments.
-
Display: 2-line x 16-character backlit LCD.
-
Interface: 19-key tactile feedback membrane keypad.
-
Connectivity: Connects to the processor via the DH-485 port using a 1747-C10 (or similar) interconnect cable.
2. Technical Parameters

| Current Rating | 104 mA (at 24V DC) |
| Operating Modes | Monitor Mode and Modify Mode |
| Operating Temp | 0 to 55 °C (32 to 131 °F) |
| Humidity | 5% to 95% (non-condensing) |
| Dimensions | Approx. 152 x 139.7 mm (Front Panel) |
| Mounting | Panel Mount (NEMA 12/13 rated when installed) |
| Language Support | English, French, German, Italian, Spanish, Japanese |
3. Key Advantages
-
Real-Time Data Access: Enables immediate viewing and changing of bit, integer, and timer/counter values.
-
Operational Control: Operators can switch the processor between RUN and HALT modes directly from the module.
-
Diagnostic Capability: Quickly view and clear processor faults on the factory floor, reducing downtime.
-
Ease of Use: No complex software is required for basic data table access; it utilizes simple menu-driven navigation.
-
Durability: Designed for industrial use with a rugged enclosure and protection against dust and moisture.
4. Product Applications
-
Machine Setup: Adjusting setpoints, timers, and counter presets during production changeovers.
-
Process Monitoring: Tracking real-time variables like temperature, pressure, or piece counts in manufacturing cells.
-
Maintenance & Troubleshooting: Identifying error codes and clearing minor faults without a laptop.
-
Standalone Interface: Small-scale automation systems where a full HMI (Human Machine Interface) is not cost-effective.
5. Important Considerations & Precautions
-
Unsupported Data Types: It does not support Floating Point, String, or ASCII data values.
-
Compatibility: While it works with most SLC 500 processors, some operations (like mode switching) on an SLC 5/03 or later require the CPU keyswitch to be in the REM (Remote) position.
-
Discontinued Status: The 1747-DTAM is considered an “Obsolete/Discontinued” product by Rockwell Automation. New systems typically use PanelView terminals, though the DTAM is still widely available in the surplus/refurbished market.
-
Ventilation: Ensure the top and bottom ventilation holes remain unobstructed to prevent overheating.
-
Power Source: Ensure the 24V DC power supply is stable; improper voltage can damage the liquid crystal display.
