clean air and
non-aggressive, non-combustible gases
In the absence of current delivery
(under currentless conditions)
can be configured and addressed via DIP switch!
RS 485, galvanically isolated,
Bus termination activatable via DIP switches.
Up to 32 devices possible in one segment.
In case of a greater number of devices,
RS485 transceivers must be used. °C
Modbus (RTU mode),
address range 0...247 selectable
Plug for
9600, 19200, 38400 Baud
