●Can be used in the environments between -20 and 60 degrees Celsius and adaptive to cold district.
●Environment-friendly design by using lead-free solder, without hexavalent chromium screw.
●Can be hung on the wall by screwing from upper side.(-L model)
SI-65FA: Standard model
SI-65FA-L: Wall-hanging model
SI-65FA / SI-65FA-L are an interface converter to connect equipments such as equipment for factory automation or analyzers which have RS-422/485 communication ports to LAN. The built-in Lantronix Xport® on the LAN interface converts RS-422/RS-485 data into LAN protocol (TCP/IP and transfers the LAN data by controlling RS-485 driver automatically. It offers high reliability by insulating between LAN and RS-422/485 interfaces by the photo-coupler. It works without AC adapter by built-in wide AC input. It has the robust metal body and supports 35mm DIN rail, and can be used under the environment of –20 degrees Celsius. Therefore, you can use it for factory automation without worry.
