PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1747-DTAM is an SLC 500 Data Table Access Module. It provides plant floor operator interface functions for SLC 500 modular and fixed controllers. Operators use the module to modify file information, alter CPU operating modes, and transfer memory. The unit also monitors, displays, and clears active processor faults. It connects directly to processors using dedicated serial interface cables.
The module features a sealed nineteen-key membrane keypad providing tactile feedback. A two-line dot matrix backlit liquid crystal display presents sixteen characters per line. Users can adjust screen contrast to maintain visibility across various ambient lighting environments. The hardware supports six selectable system languages for global plant integration. Factory defaults configure communication at nineteen point two kilobaud with node address zero.
