A twin timer is a type of timer relay function that allows the ON time and OFF time to be set independently.
Flicker operations can be set for timer relays. Flicker operation is an operation in which the ON time and OFF time continue to repeat alternately when a voltage or start signal is applied to the relay.
In a normal flicker operation, only one ON time and one OFF time can be set in common, but in a timer relay with a twin timer function, each of these can be set individually.
Twin timers are used in electronic devices and machinery that require flicker operation. Typical examples are lamps and signal towers. Twin timers are also used in machines that need to be run and stopped repeatedly at regular intervals.
For example, a lamp may be turned on for 5 seconds and then off for 3 seconds, or a gear may be rotated for 3 seconds and then stopped for 5 seconds, etc. Twin timers are used when the device must be set to turn on and off separately.
The interior of a timer relay consists of four parts: an input part, a timekeeping part, a power supply part, and an output part.
The input section receives signals from the device and passes them to the timekeeping section. The timekeeping section measures time and passes the signal to the output section after a set time has elapsed. The output section then outputs the signal to various devices. The power supply section will supply voltage to the timer relay. When the power supply part of the timer relay is turned on, or when a signal for start is sent to the input part while the power supply voltage is applied, the timer relay starts operating.
In addition to flicker operation, timer relays have other modes of operation, such as on-delay operation, off-delay operation, and interval operation. The twin timers are one of these timer relays that performs flicker operation. When the timer relay is set to off-start, it repeats the process of off/on/off, and in the case of on-start, it repeats the process of on/off/on.
With twin timers, the on-time and off-time can be set alternately, and this allows the timekeeping unit to either send a signal to the output section or stop the signal.
