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.

First referenceCompare with

K RC

IEEE / ANSI

ANSI/IEEE relay coil with rc suppression symbol

The RC-suppressed relay form associates resistance and capacitance with the operating circuit. Its actual network location and compatibility come from the selected assembly, while the contact circuit remains separately referenced.

Drawing use: Schematic
Application: Control circuits
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Relays with Suppression 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

An RC network and a diode suppressor are different component arrangements, not interchangeable graphic decorations.

K RC

Symbols

Relay coil with RC suppression

A relay RC suppression network uses resistance and capacitance associated with the coil circuit. It provides a documented transient-control function with characteristics distinct from diode suppression.

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

A distinction that matters

RC suppression and diode suppression are not interchangeable annotations for every supply type.
