Connect Tech Xtreme/PCI-104 Opto - PCI-104 Twelve Port Opto Isolated Serial Interface Card

Adds 12 RS232, RS422 or RS485 Isolated Interfaces to PCI-104 Bus


Connect Tech’s robust Xtreme product family now includes high density optical isolation as an additional feature to its product offering. Xtreme/PCI-104 Opto provides the highest port density, with 12 ports on a PCI-104 card, along with the added protection of 1kV optical isolation on a rugged and compact form factor.

Dependability, high speed data transfer rates and 1kV of optical isolation protection makes these cards ideal for critical applications whereby harsh conditions may disrupt communications .

Use Xtreme/PCI-104 Opto for embedded systems in the military, aerospace, medical and industrial sectors.

Features and Benefits

  • Flexibility: 12 RS-232/422/485 optically isolated serial ports
  • Speed: Data rates up to 1 Mbps RS-232 and 4.16 Mbps RS-422/485
  • Performance: Each port is controlled by a high performance UART, providing 64 bytes of transmit and receive FIFO buffers
  • Adaptability: Supports full duplex (4-wire) half duplex (2-wire) and multi-drop (4-wire) in RS-422/485 mode
  • Ruggedness: Operates within a temperature range of -40 degrees Celsius to 85 degrees Celsius (-40°F to 185°F)
