Relay coil with RC suppression
A relay RC suppression network uses resistance and capacitance associated with the coil circuit.
Schematic · K RC
What it represents
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.
How to read it
- Confirm whether the RC module is internal, in the socket or separately wired.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Show network location
- State coil supply
- Reference compatible suppression unit
A distinction that matters
RC suppression and diode suppression are not interchangeable annotations for every supply type.
