I-7520 with 3000V DC isolation at RS-485 side
Input : RS-232 protocol
Output : RS-485 protocol
Speed : auto switching baud rate, 300~115200 bps
"Self Tuner" inside
256 modules max. in one RS-485 network without repeater
2048 modules max. in one RS-485 network with repeater
Isolation voltage : 3000Vdc at RS-485 side
Repeater request : 4,000 feet or over 256 modules
Power consumption : 2.2W max.
This model is used for PLC user. The design of isolation between I-7520 and I-7520R is different.
If the user want to supply the power from PLC, he should use the I-7520R. Otherwise the isolation will be broken.
Please refer to the manual I-7000 bus converter for detail information
