RDL TX-PCR1 Paging Controlled Relay Switching Functions Controlled by Speaker Level Source - Power Supply Included
The TXPCR1 is the ideal choice in many applications where switching needs to be controlled from a constantvoltage amplified audio source. The module will trigger on any program material, with paging sources being the most common. The TXPCR1 includes both an opencollector SLAVE output to control other modules or equipment and a DPDT high power switching relay suited to switching speaker loads. The amplified audio source is connected using a detachable terminal block. A front-panel switch is provided to select the source type 25 V, 70 V or 100 V. The 25 V setting may be used for an 8 ohm, 75 Watt maximum, amplified source. Input sensitivity is adjusted on a singleturn trimmer. In the clockwise position, the SENSITIVITY trigger threshold is 30 dB below the switch-selected constant voltage. A red LED illuminates whenever the audio level exceeds the trigger threshold, facilitating the sensitivity adjustment. The module is triggered when the audio exceeds the threshold and it remains triggered for a defined time duration after the audio falls below the threshold. This DELAY is adjustable from 3 to 25 seconds using a front-panel trimmer. Adjustment is simplified by a green LED that remains illuminated while the module is triggered. The SLAVE terminal may be used as either an input or output control terminal. When the module is triggered, the SLAVE terminal is internally pulled to ground through an open collector. If the TXPCR1 SLAVE terminal is externally pulled to ground through a switch or the opencollector terminal of another RDL module, the relay will energize until the terminal is released. A blue POWER LED illuminates when the TXPCR1 is powered from an external 24 Vdc power supply. Use the TXPCR1 relay contacts to switch speaker lines or to control the logic inputs of other equipment with control inputs that may not be pulled up to 24 V. The TXPCR1 is ideal to provide local speaker muting during an area page. - Power Supply Included

I need to build a circuit that switches a voltage source (5V) on and off every 5 seconds. What do I need to buy and understand to assemble the circuit? The switch must be done automatically and would be more useful if I can make it switch 4 times every second.
And got the following answer:
You can use a 555 timer chip and a few assorted parts. You can then drive a power transistor or darlington pair to turn off and on a relay. This would be a very inexpensive solution. Tutorial on the 555 at the address below.
