Figure 31 RS 485 channel, example of installation
Note: In the last instrument of the chain, Instrument 1 in the example, the connections appearing on
the detail (390 Ohms resistors) scheme must be carried out.
To receive data from the PC, it is necessary the connection of one convertor USB to
RS 485. The convertor USB incorporates one telephonic connector, for this reason, the
cable for connection to the PC (cable 3 in the example) is different from the rest. It should
have telephonic connector.
DANGER
Relays: Limit the current up to 3A by using one fuse. Do not connect cables with voltage higher
than 24 V.
