COUNT TOTAL Non-resettable counter relay: original educational illustration

Symbols

Non-resettable counter relay

A non-resettable counter records events without a normal user reset function. It is used where the total event history is part of the documented equipment indication.

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

A distinction that matters

A totalising counter is different from a preset counter intended to be reset each operating cycle.

Coil

Symbols

Relay coil

A relay coil represents an operating element that changes the state of associated contacts when the device operates. Coil and contact representations are often drawn in different locations to make the circuit easier to read. Their shared identifier and cross-references establish the relationship.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / IEEE / ANSI

A distinction that matters

A relay coil is not a contactor power pole. Similar operating-element marks can represent equipment with different switching duties.
