PRODUCT INFORMATION
Product Overview
The Allen-Bradley SST-PB3M-CPX is a CompactLogix Communication Module for industrial automation systems. This module operates as a PROFIBUS Master interface within the control architecture. It connects CompactLogix controllers to distributed PROFIBUS field devices and remote networks. The unit manages up to 1,984 bytes of input data per master. It also handles up to 1,968 bytes of output data per cycle.
The module supports connectivity for up to 125 PROFIBUS slave devices. Physical field bus connection is established through a DB9 female D-Sub connector. Supported PROFIBUS transmission speeds range from 9.6 Kbps up to 12 Mbps. An integrated 10/100 Mbps RJ-45 Ethernet port provides additional networking capability. The unit operates in ambient temperatures between 0 °C and 60 °C.
