The ISO-485-P is a high quality, rugged industrial-grade passive bi-directional 2 wire (485+ 485-) surge suppressor with built-in terminal blocks.  The surge suppressor is compact.  It provides 3 levels of surge suppression and can protect any standard RS-485 port from voltage surges, peaks and spikes caused by lightning and other power surge conditions.  The  ISO-485-P protects the two lines 485+ and 485-.  The unit is passive therefore, no external power or flow control is required.  The ISO-485-P has  a 3-wire terminal block on the one RS485 side and a 2-wire terminal block on the other RS485 side.  Operates reliably from 300 to 115.2K bps.

Quantity: 

The ISO-ETH-P is a high quality, rugged industrial-grade passive bi-directional Ethernet surge suppressor.  It can protect any standard 10Base-T/100Base-TX Ethernet port from voltage surges, peaks and spikes caused by lightning and other power surge conditions.  The unit is passive therefore, no external power or flow control is required.  The ISO-ETH-P has a Rj45 female on one Ethernet side and another RJ45 on the other Ethernet side.  Operates reliably up to 100 mbps.

Quantity: 

The REP-485/422-9E is a high quality external powered industrial bi-directional 2.5KV RS-485/RS-422 isolator / Repeater with 15KV ESD and 600W surge protection.  It can also convert RS485 to RS422 and vice versa as well as extend RS485 or RS422 up to 4000 ft (1.2km).  This converter features two DB9 connectors with two optional terminal blocks.  Operates reliably from 300 to 115.2K bps.

Quantity: 

The CON-485/422-REP is a rugged industrial-grade high quality external powered bi-directional 3KV RS485 / RS422 isolator with 15KV ESD and 600W surge protection.  I can also convert RS232 to RS485 or RS422 converter as well as repeat RS485 or RS422 and extend data distance up to 9800 ft (3km).  This is our most versatile serial converter with DC input from 12V to 36V or AC input from 100VAC to 240VAC.  This converter comes with built-in terminal blocks and housed in a steel case.  Operates reliably from 300 to 115.2K bps.

Quantity: 

The ISO-485-PI9 is a high quality industrial-grade bi-directional opto-isolated port powered RS232 to RS485 converter with 15KV ESD and 600W surge protection in a 9 pin format.  It provides 2500V optical isolation which effectively protects your devices from voltage surges, ground loop conditions and noise problems.. Operates reliably from 300 to 57.6K bps.

Quantity: 

The CON-485/422-EE9 is a high quality industrial-grade standalone, panel, or rack mounted bi-directional externally powered opto-isolated RS232 to 2-wire RS485 or 4-wire RS422 converter with 15KV ESD and 600 W surge protection in a 9 pin or RJ45 format.  The unit is externally powered so you do not have to worry about your RS232 device's ability to port power the converter.  The converter features optical isolation which provides effective protection for your devices from voltage surges, ground loop conditions and noise problems.  Operates reliably from 0 to 115.2K bps.

Quantity: 

The CON-485/422-EE4 is a high quality industrial-grade standalone, panel, or rack mounted bi-directional externally powered opto-isolated RS-232 to 4-wire RS485 or 4-wire RS422 converter with 15KV ESD and 600W/ surge protection in a 9 pin or RJ45 format.  The unit is externally powered so you do not have to worry about your RS232 device's ability to port power the converter.  The converter features optical isolation which provides  effective protection for your devices from voltage surges, ground loop conditions and noise problems.  Operates reliably from 0 to 115.2K bps.
