I/O connection to the machine logic
The P3UP gauge may be fitted with various types of machine I/O:
“I/O TYPE A” relays outputs with N.A. contact (normally open)
“I/O TYPE B” Opto-isolated
“I/O TYPE C” Outputs with exchanged relays;
Each type features one or two variants that are identified by a dedicated “I/O TYPE xx” label where the type
identifier letter (A, B, C) is followed by a number that indicates the variant.
IMPORTANT
The symbol on the left is present on the H1 connector together with a label indicating “I/O TYPE
xx” This label indicates the exact type of I/O installed on the unit and the associated wiring
specifications.

N.B. (*CURRENT AND VOLTAGE VALUES)
All the a.c. current and voltage values are r.m.s., the frequency is 50-60 Hz (-
6%/+5%). The
total r.m.s. content of the pure harmonics (integer multiples of the nominal frequency) not
exceeding 10 times the nominal frequency may constitute up to 10% of the total voltage. The
total content of harmonics and other frequencies above this level may constitute up to 2% of the
total voltage.
