1. General description
8
IO 351 is a module for exchange of digital and
8
analog signals between CU 351 and the remaining
9
electrical system via GENIbus. IO 351 comes in the
9
variants A and B.
IO 351 A is used for one to three Grundfos pumps
9
with fixed speed.
9
IO 351 B is used for one to six Grundfos pumps with
10
fixed speed and/or pumps controlled by external
10
frequency converters. The module can also be used
10
as an input-output module for communication with
monitoring equipment or another external
10
equipment.
