1.3 Common Features of the 7000 Series
Isolation voltage: 3000 VDC
Communication:
• Asynchronous half-duplex 2-wire RS-485 network
• Max. Distance without repeater= 1.2Km
• Speed=1200,2400,4800,9600,19200,38400,57600,115200
• Connecting 256 modules in one RS-485 bus without repeater
• Multiple baud rate and multiple data format can share the same
RS-485 bus (7520/7510)
• Different baud rate 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.
• 7000 series data format=1 start + 8 data + 1 stop + no parity = 10-bit
• Two extra checksum bytes can be enable/disable
• Built-in transient voltage suppresser and PTC protector
• Sharing the same RS-485 bus with the RS-485 or RS-232 device,
which communicates in multiple data format (not 10-bit) and multiple
bauds Rate. (Use 7520 to convert RS-232 to RS-485)
Power requirement:
• Unregulated +10V dc ~ +30V dc.
• Power reverse protection, Over-voltage brown-out protection
System:
• Dual watchdog inside, power-on start value and safe value for host
failure
• Operating temperature: -25 to 75ºC (14 to 185ºF)
• Storage temperature: -25 to 80ºC (-13 to 185ºF)
• Humidity: 5 to 95%, non-condensing
