2. NC Terminal:
The NC terminal is used internally. Therefore, do not connect anything
to the NC terminal.
Inner-layer Pattern for Noise Protection
When adding a noise protection circuit to the input or output section, create
inner-layer patterns as follows:
There must be at least 2.54 mm between the adjacent inner-layer patterns
of the external and internal circuits.
The inner-layer pattern of the external circuit must be kept at least 10 mm
from each terminal of the SRT@-ID16P or SRT@-OD16P,
No parts must be mounted on the soldered surfaces around the SRT@-ID16P
or SRT@-OD16P.
