A 'Time Delay on Pickup Relay' is a useful application when you desire to have a device (output) turn on based upon a signal from another source (input). When the input (signal) senses a false to true transition, a timer will begin timing. When the timer reaches it's pre-programmed setpoint value, the output (device) is then turned on. The output will be maintained as long as the input is maintained. At any point, if the input goes false, the output will also go false.
