Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

LS FLOAT NO

Symbols

Float level switch NO

A float-operated NO level switch changes contact state through a float mechanism at a documented fluid level. Schematics need the rising or falling level action as well as the contact reference state.

A distinction that matters

A float switch is a discrete level device rather than a continuous level transmitter.

PLC I/O

Symbols

PLC input / output

A PLC input or output point connects a field signal with a controller module and channel. Input and output, digital and analogue, and one-wire or multi-wire arrangements are distinct characteristics. The module specification establishes electrical behaviour and terminal information.

A distinction that matters

An input point, output point and communications connection are different interfaces. A generic box cannot establish their electrical compatibility.
