PRODUCT INFORMATION
Product Overview
The Allen-Bradley SST-PB3-CLX-RLL is a ControlLogix chassis module manufactured by Molex for industrial PROFIBUS networks. This single-slot module installs directly into any available slot of a 1756 chassis. It enables communication between Logix processors and remote PROFIBUS DP slave devices. Up to eight scanner modules can operate within a single ControlLogix rack. The unit provides one nine-pin female D-sub connection supporting up to 125 slave nodes.
Engineers configure the unit using the dedicated SST PROFIBUS configuration software tool. Input and output process data map directly into ControlLogix 5550 controller data arrays. Front diagnostics include an LCD display panel alongside COMM, SYS, and OK status indicator LEDs. The hardware operates within an ambient temperature range from 0 to 60 degrees Celsius. It also supports integration within Honeywell PlantScape distributed control systems.
