To choose a time delay relay, evaluate 6 criteria: the timing function type (on-delay, off-delay, cyclic, or interval), the timing range (milliseconds to hours), supply voltage (12 V to 240 V AC/DC), contact load capacity (current rating and load type), mounting format. To choose a time delay relay, evaluate 6 criteria: the timing function type (on-delay, off-delay, cyclic, or interval), the timing range (milliseconds to hours), supply voltage (12 V to 240 V AC/DC), contact load capacity (current rating and load type), mounting format. A time switch, also called a timer switch, is an electrical control device that automatically turns a circuit on or off according to a preset time schedule. Use time relays for delay-on, delay-off, interval timing, cyclic timing, star-delta motor starting, lighting control, conveyor sequencing, and protection sequences. The. Time delay relays and solid state timers use solid state electronic devices to provide a time delay. They may have displays, pots or other means of operator interface. The quick brown fox jumped over the lazy dog. This article will explain what time delay relays.
