The SS3580-USB is an isolated interface converter between USB port and asynchronous serials lines RS-485 or RS-422 that guarantees a full isolation between power supply, USB and serial line RS-485 or 422, removes eventual ground-loop effects, allowing the use of the device even in the heavy environmental conditions.
Call for price
The SS3580-USB is an isolated interface converter between USB port and asynchronous serials lines RS-485 or RS-422 that guarantees a full isolation between power supply, USB and serial line RS-485 or 422, removes eventual ground-loop effects, allowing the use of the device even in the heavy environmental conditions.
It is designed to operate either on serial interface RS-422 full-duplex 4 wires or RS485 half-duplex 2 wires, with a baud-rate transmission up to 115.2 Kbps. The transmission is asynchronous without settings of protocol, data format and baud rate.
The SS3580-USB is in compliance with the 89/336/EEC directive on the electromagnetic compatibility. The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 22.5 mm only, allows a high density mounting on EN-50022 standard DIN rail.
