RDL TX-PCR1 Paging Controlled Relay Switching Functions Controlled by Speaker Level Source - Power Supply Included

  • Switching Functions Controlled by Speaker-Level Source.
  • Input Accepts Amplified Constant Voltage Signals.
  • Switch-Selectable Input 25 V, 70 V, 100 V.
  • 25 Volt Input Also Accepts 8 Inputs up to 75 Watts.
  • Transformer-Isolated Input.

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

Cameron C asked How to control a high voltage device with low voltage circuit?

i am building a hover craft out of computer fans and an old RC car circuit. How i give the fans a high voltage through a circuit that has a low voltage. the circuit has a max of 7.5 volts and the fans need about 24 volts. How can i acheive this with out melting the circuit? Thanks in advance

And got the following answer:

I believe you could use a relay switch. Frow wikipedia (http://en.wikipedia.org/wiki/Relay) "A relay is an electrical switch that opens and closes under the control of another electrical circuit. In the original form, the switch is operated by an electromagnet to open or close one or many sets of contacts. It was invented by Joseph Henry in 1835. Because a relay is able to control an output circuit of higher power than the input circuit, it can be considered to be, in a broad sense, a form of an electrical amplifier."

The computer controlled relay switch perform really effectively with diverse applications which can be distinct to power distribution and protection. The relays include wide adjustment ranges having a scale that’s easy to study either in three or four digits as outlined by the model. These computer controlled relay switch assistance in rising the flexibility on the applications, lower the all round power and upkeep charges. There are actually relays that are utilised for basic purposes which are available in trustworthy styles with speedy replacement options. And you will find models which are made use of for industrial applications and heavier duty applications that work on big loads. These goods are created to meet the lifetime industrial control wants on the applications.
Their most current items would be the Time counter, Timer Delay, computer controlled relay switch, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and many other individuals. The web page offers a detailed description of every model in numerous categories of computer controlled relay switch couplings and sensors. These products are incredibly helpful for high-risk applications. The computer controlled relay switch are also obtainable with characteristics like numerous timing ranges and functions. The business is presently looking for agents and dealers who can market and sell their factory created products. They’re usually on a lookout for developing new and more trusted items according to the demands and specifications with the business.
