Isolation Voltage : 3000V DC
Communication :

• Asynchronous half-duplex 2-wire RS-485 network
• Max. distance without repeater=4000 feet(1.2Km)
• Speed=1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
• A maximum of 256 Modules can be connected in a single RS-485 bus without using a repeater
• Multiple baud rates and multiple data formats can share the same RS-485 bus(I-7520/7510)
• Different baud rates and the same module address can share the same RS-485 bus
• Connecting 256*8=2048 modules max. in one RS-485 bus with repeater.
• I-7000 series data format = 1 start + 8 data + 1 stop + no parity = 10-bit
• Two extra checksum bytes can be enabled/disabled
• Built-in transient voltage suppresser and PTC protector
• Sharing the same RS-485 bus with a RS-485 or RS-232 device that communicates in multiple data format
  not 10-bit) and multiple baud rate. (Use I-7520 to convert from RS-232 to RS-485)
