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.

• Humidity: 5% to 95% non-condensing
– Key Features
• Network LED indicates card activity with solid green operation, red/green flicker on error, rapid flicker during transmission
• SYS LED shows firmware status: solid red before download, off after successful load, remains red on loader failure
• Static-sensitive design requires anti-static bag storage and grounding wrist strap during handling
• Supports multiple PCI adapters and dual-channel configurations via Wonderware I/O Servers
– Typical Applications
• Legacy DH+ network integration with contemporary PC-based control systems
• Allen-Bradley PLC-5 and SLC platform connectivity
• Industrial machine control and process monitoring over DH+ infrastructure
