Network controller – GWAB11
Network Controllers – GWAB11 has four inputs for up to four GWNET11s in series. A total of 16 temperature lines per input and a maximum of 64 temperature lines per GWAB11.
Up to seven GWAB11 can be connected in series.
The connection is made with a signal cable according to a special specification.
ATEX and IECEx approved.
