Definitions:

On-Delay Timer

An electromechanical relay with contacts that change state a predetermined time period after the coil is energized; the contacts return to their shelf state immediately on de-energization of the coil; also, a programmable logic controller instruction that emulates the operation of the electromechanical on-delay timer.

Ladder Rung

A horizontal section of a ladder logic diagram, representing a specific logic operation in PLC programming.

Off-Delay Timer

An electromechanical relay with contacts that change state a predetermined time period after power is removed from its coil; on re-energization of the coil, the contacts return to their shelf state immediately; also, a programmable logic controller instruction that emulates the operation of the electromechanical off-delay relay.

Ladder Rung

A single line of logic in a ladder diagram that equates to a control circuit, usually comprised of inputs and outputs represented by symbols.
