Side-by-side reference

Understand the difference.

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

IEEE / ANSI

ANSI/IEEE polarised relay coil symbol

The polarised-relay form indicates a documented sensitivity to input polarity or direction. The schematic's terminal labels and polarity reference must remain intact when the element is rearranged, because page orientation does not establish electrical polarity.

Drawing use: Schematic
Application: Control circuits
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Relays and Contacts functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

Polarised operation differs from the polarity restriction introduced solely by a suppression diode on an ordinary relay coil.

K POL

Symbols

Polarised relay coil

A polarised relay has operation or a specified response that depends on the documented electrical polarity. Its terminal and polarity markings must be preserved when the drawing is rearranged.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / Manufacturer

A distinction that matters

Polarised relay operation is different from merely fitting a suppression diode to an otherwise ordinary coil.
