Level Transmitter:
• Low: -5 V ≤ V
A-B
≤ -1,5 V
• High: +5 V ≥ V
A-B
≥ +1,5 V
Receiver:
• Low: V
A-B
≤ -0,2 V
• High: V
A-B
≥ +0,2 V
Transmitter and receiver are surge-proof for voltages between A and GND
EXT
as well
as between B and GND
EXT
in the range of -7 V to +12 V.
Max. number of
modules at the bus
32 (according to the RS485 standard)
If more then 32 devices are needed, RS485 repeaters which support bit retiming have
to be used.
