DeLOCK 65841 Internal Serial Adapter

The DeLOCK 65841 is an internal serial adapter with a PCIe host interface, designed for integration into PCs and Mini-PCs. It provides RS‑422/485 connectivity for industrial fieldbus systems, machine controllers, converters and measurement data acquisition. The card uses the Exar 17V352 chipset and comes with low profile brackets for installation in compact systems.

Advantages

The adapter supports multiple serial configurations (data bits 5, 6, 7, 8 and stop bits 1, 1.5, 2) and offers extensive overvoltage protection and an extended operating temperature range for reliable operation in demanding environments. Its low‑profile form factor and compact dimensions (91 × 12 × 64 mm) simplify mounting in standard and small form‑factor cases. Compatibility with Windows Server 2012 R2 and Windows Server 2016 makes it suitable for server use.

Suitable for

• Industrial fieldbus systems
• Machine controllers and automation equipment
• Signal converters and RS‑422/485 devices
• Measurement data acquisition and monitoring systems
• Installation in Mini‑PCs and space‑restricted PC cases
