Allen-Bradley 1747-DTAM-E Data Table Access Module

The Allen-Bradley 1747-DTAM-E Data Table Access Module is an operator interface designed for SLC 500 controllers that lets technicians access data file information, switch operating modes, monitor and clear processor faults, and perform memory transfers with any SLC 500 family processor. It uses a compact LED-backlit monochrome display, 2 lines by 16 characters, enabling on-rack viewing of data-table contents and system status without external tools. The module is powered from the CPU via 24V DC and requires the 1747-C10 cable for operation, aligning with the standard connections used in SLC 500 installations. Key capabilities include reading and editing data table entries, navigating between data sets, and triggering diagnostic actions through the DTAM’s built-in interface. Typical applications cover on-site data table inspection during commissioning or maintenance, quick fault diagnosis and clearing, and memory transfer tasks to move data between the controller and its programs. Catalog number 1747-DTAM-E denotes this particular DTAM variant, a plant-floor device intended to integrate with 1747 backplanes in SLC 500 racks and to interact with compatible processors in real time.
