The SST-DHP-PCI is a 32-bit PCI interface card that bridges modern PC systems with legacy Data Highway Plus (DH+) industrial networks. It enables direct communication with Allen-Bradley PLCs and DH+ networked devices, supporting machine control, data acquisition, and process monitoring through a standard PCI 2.2/2.3 slot. The card handles three DH+ data rates and includes 1771 Remote I/O protocol support in adapter or scanner mode.
