Industrial USB to RS485 / RS422 converter working temperatu ... Read more

Industrial USB to RS485 / RS422 converter working temperatures from -40 to +85 degree Celsius. The housing is made of hardened ABS plastic with a reinforced terminal header for easy connection of communication wires. This USB to RS485 / RS422 converter is electrically protected against static electricity, high voltage spikes and other dangerous voltage spikes which can damage your equipment or data signaling. This protection is accomplished by four TVS's (Transient Voltage Suppressors), one for each data line. This converter is made in particular for industrial environments but is also suitable for most other applications including any general office, commercial and laboratory environment. It is a bi-directional, (meaning it communicates in both directions) and reliable converter that easily lets you connect any RS485 or RS422 device directly to your computer's USB port, efficiently converting USB signals to half-duplex RS485 or full-duplex RS422 and vice versa. The RS485 / RS422 end is a standard 5-terminal screw header for easy connection of single wires. Automatic send data control is enabled by default so no external flow or handshake control is needed.
