RDL TX-PCR1 Paging Controlled Relay

Take control of your audio system with the innovative TX-PCR1 Paging Controlled Relay, a top-tier product from the reputable brand, RDL. This high-quality, durable device is designed to manage switching needs from a constant-voltage amplified audio source, making it an ideal solution for various applications, particularly those involving paging sources.

The TX-PCR1 is equipped with an open-collector SLAVE output, which allows you to control other modules or equipment seamlessly. It also features a DPDT high power switching relay, perfectly suited for switching speaker loads. The amplified audio source can be connected via a detachable terminal block, providing user-friendly operation.

This reliable device offers a front-panel switch for selecting the source type: 25 V, 70 V, or 100 V. The 25 V setting can be used for an 8 ohm, 75 Watt maximum, amplified source. The input sensitivity can be easily adjusted with a single-turn trimmer, and a red LED illuminates when the audio level exceeds the trigger threshold, making sensitivity adjustment a breeze.

The TX-PCR1 is triggered when the audio surpasses the threshold and 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, and a green LED stays illuminated while the module is triggered, simplifying the adjustment process.

The SLAVE terminal can function 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. A blue POWER LED illuminates when the TX-PCR1 is powered from an external 24 Vdc power supply.

The TX-PCR1 is perfect for providing local speaker muting during an area page. The double pole contacts allow local speakers to be automatically connected to a paging line during a page and reconnected to the local amplifier when the page is completed. For controlling additional speaker lines, the SLAVE terminal can be used to manage additional TX-PCR1 modules or RDL ST-LCR1H High Power Logic Controlled Relays.

In summary, the TX-PCR1 Paging Controlled Relay offers a comprehensive solution for managing your loudspeaker system, ensuring high-quality audio control for your specific needs.
