The Woodward SST-PFB-PLC5 enables seamless ProfiBus DP connectivity for Allen-Bradley PLC-5 processors. This co-processor module operates in a master/scanner mode on the ProfiBus DP network. Consequently, it allows the PLC-5 to directly command and monitor remote slave devices. The module installs directly within a 1771 I/O chassis adjacent to the main processor.
Robust Physical and Electrical Design
This SST module features a durable metal housing for harsh industrial environments. It draws 1.5 Amps at 5 Volts DC from the chassis backplane for operation. Furthermore, the unit provides clear status indication through its OK, SYS, and COM LED indicators. This robust design ensures reliable communication in demanding automation applications.
Comprehensive Communication Interfaces
The SST-PFB-PLC5 integrates four distinct communication interfaces for maximum flexibility. A 9-pin female D-shell connector serves as the ProfiBus DP network port. Additionally, a 9-pin male D-shell RS-232 port allows for direct PC configuration and monitoring. The 58-pin processor interface connects directly to the PLC-5’s parallel port.
