Connect Tech Xtreme/104-Plus Opto - PC/104-Plus Four Port Isolated Serial Interface Card

Adds Four RS232, RS422 or RS485 Interfaces to PC/104-Plus Bus with Opto Isolation


Connect Tech's robust Xtreme/104-Plus product family has introduced optical isolation as an additional feature to its product offering. Xtreme/104-Plus Opto provides the added protection of 3kV optical isolation on a rugged and compact form factor for your critical applications.

PCI 2.3 and PC/104 2.0 compliant, this PC/104-Plus card includes a PC/104 pass-through connector for compatibility with legacy PC/104 cards.

Dependability, high speed data transfer rates and 3kV of optical isolation protection make these cards ideal in environments where harsh conditions may disrupt communications.

Use Xtreme/104-Plus Opto for embedded systems in the military, aerospace, medical and industrial sectors. Lifetime Warranty and free technical support are also included.
