SST-PB3-PCU-2 (Molex/Woodhead SST | Dual Channel PROFIBUS-DP PCI Industrial Communication Network Card)

SST-PB3-PCU-2 physical object

1、 Product Details
Brand: Molex (formerly Woodhead SST Brad) | Type: PCI bus dual channel PROFIBUS-DP communication card, PCU-2 is a dual DB9 interface upgraded version (PCU single channel upgraded version)
core functionality
Installation of PCI slots on industrial control computers, with two independent PROFIBUS-DP buses that can be configured independently: DP master station/DP slave station/FDL layer 2 message, without interfering with each other; One line is connected to on-site frequency converters/remote I/O, and the other line is connected to PLC systems. One card shares the load of two DP buses, solving the problem of too many lagging nodes on a single channel bus.
Equipped with an independent 32-bit ColdFire hardware processor and onboard Flash firmware, the protocol calculation is independent and does not occupy CPU resources of the industrial control host;
Supporting SST configuration software, OPC DA service, DLL driver CommDTM， Compatible with Intouch/IFIX/Kingview/WinCC upper software;
Dual DB9-PROFIBUS interface on the panel, multiple status indicator lights (power supply, bus fault, channel communication, watchdog), fast fault location;
The original factory has discontinued EOL production, and only new inventory and refurbished spare parts are circulating in the market.
Product advantages
Dual channel isolated bus design, electrically isolated between two DP networks, with a single bus short circuit not affecting the other communication channel; Support DPV0/DPV1 full protocol, compatible with Siemens S7-300/400, Emerson, AB supporting DP slave equipment.
