INTERCONNECTING PRODUCTS AND CABLES I-7520 Isolated RS-232 to RS-422/485 Converters ■ Description The I-7520 Series RS-232 to RS-422/RS485 Converters provide a unique mix of RS485 protocol conversion and isolation. All three models provide RS-232 to RS-485 protocol conversion at rates up to 115,200 baud. www.DataSheet4U.com A proprietary auto tuner circuit detects the baud rate and data format automatically and controls the direction of the RS-485 circuit. This eliminates the need to control the module with the Request-to-send line as is done with some other devices. The three models give the user a choice of which side is isolated. The 7520 and 7520R drive RS-485 2-wire half-duplex lines. The Model 7520A has a RS-422/RS-485 port which can drive a full-duplex 4-wire circuit or a 2-wire halfduplex circuit. ■ Converts RS-232 to RS-485 or RS-422 signals. Drive long lines to RS-485 or RS-422 devices. Auto tuner circuit for baud rates from 300-115200 baud. Handles multiple data rates. 3000 V Isolation Prevents ground loops and electrical damage. Converts serial devices to Ethernet network Overcomes the two COM port limit. Mounts on standard DIN rail. Easy mounting and replacement. Available in 3 versions. Isolate either port. Approved ■ ■ ■ I-7520 ■ 7520 Model Selection The primary difference between the three models is the isolated side. For the I-7520, power and ground are applied on the RS485 side. The RS-232 side is powered by an internal DC-to-DC converter. The RS-232...
