In the following input wiring diagrams,
• "NC" terminals are not intended for use as connection
points.
• Using a two-wire sensor may needs an additional circuit
configuration so that total current consumption does
not exceed the allowable current consumption.
• For all NX7 and NX7s controllers, all the commons on
the input terminal block are isolated internally each
other.
