Transparently convert communication data from one port each of RS-232C and RS-422/485 into Ethernet LAN packets.

The SI-70X is an interface converter that can convert communication data from RS-232C and RS-422/485 serial ports to 10Base-T/100Base-TX Ethernet LAN with a single unit. It has high reliability suitable for harsh environments in factories, featuring a robust metal housing, compatibility with 35mm DIN rail mounting, and a wide operating temperature range. It can be used as a compact and space-saving communication device server in many manufacturing lines, public facilities, inspection equipment, and medical devices.

Applications/Examples of results

■Connect RS-232C devices and RS-422/485 devices to a LAN with a single unit With the SI-70X, you can connect two RS-232C devices and RS-422/485 devices to a LAN all at once. Replacing our SI-60F and SI-65A with just one unit allows for further cost reduction, space saving, and energy saving. Compared to using one unit each of the conventional models SI-60F and SI-65A: Cost reduced by approximately 30% Power consumption reduced by approximately 53% Space reduced by approximately 38%
