301RW Wiring
The relay module is available with optional wireless communication
(301RW). Though it functions in exactly the same way and the wiring is
the same as the standard relay module, there are some minor
differences in the circuit board.
The DIP switch settings are identical for both circuit boards, only the
position of the switch on the board is different.
Two jumpers on the 301RW circuit board allow users to define whether
the unit will be used in standard Modbus communication or in Wireless

communication mode.

Wiring of communication lines depends on the
communication jumper positions: If the jumper is in
Mod/Vul position, the communication terminal
connections will be " live". If the jumper is in Wireless
position, the communication terminal connections will
be "dead"
