RS232 Optical Isolators

Summary Of Optical Isolator Models

MODEL	PHOTO	CONNECTOR	CHANNELS	GROUND ISOLATION	POWER SUPPLIES	COMMENTS	PRICE USD
OP9		DB9	8	YES	DUAL	Re-Creates the full DB-9 port of a PC. All 9 pins are isolated. Also meant for newer low power ports on PC's and Laptops (EIA-562)	$285.00
OP93		DB9	2	YES	SINGLE	Ground isolation is supported with just a single power supply system. Also meant for newer low power ports on PC's and Laptops (EIA-562)	$260.00
OP25		DB25	8	YES	DUAL	All IBM PC Compatible signals are re-created	$285.00
VA9		DB9	8	YES	DUAL	Works like Model OP9, except that total isolation of all 9 pins is proven by sight. The Visual Assurance is obtained by the use of light beams that cross two separate non-metallic enclosures.	$410.00

No Metallic Contact:
     All Photologic Optical isolators provide ground isolation in addition to signal  isolation. 
   • This means that no metallic contact exists between your computer and equipment. 
    There is no metallic  path through ground or signal lines for electrical disturbances to travel.

All Photologic Optical Isolators Feature:

• Ground Isolation
• Workability With Newer EIA-562 Low Power Serial Ports
• Non-Metallic Enclosures
• LED Traffic Indicators

OPTICAL ISOLATORS FOR RS232 COMMUNICATIONS
____________________________________________________________

Advantage of 8 Channels:
  Generally, this type of isolator is a much easier installation because  the common 9 wire interface
   (IBM Compatible)  is recreated in full.   So the isolator  can be plugged  in-line with existing cables , 
   without the need for rewiring to rearrange or support missing signals.

For Laptops Too !

• Instantly isolate laptops and PC's from external  influences.  
• Upgrade the new style low power laptop serial
   ports to work with classic legacy RS232 signals.
