The module will trigger on any program material, with paging sources being the most common. The TX-PCR1 includes both an open-collector SLAVE output to control other modules or equipment and a DPDT high power switching relay suited to switching speaker loads.\u003c\/p\u003e\u003cp\u003eThe 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 single-turn 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.\u003c\/p\u003e\u003cp\u003eThe 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 TX-PCR1 SLAVE terminal is externally pulled to ground through a switch or the open-collector terminal of another RDL module, the relay will energize until the terminal is released.\u003c\/p\u003e\u003cp\u003eA blue POWER LED illuminates when the TX-PCR1 is powered from an external 24 Vdc power supply.\u003c\/p\u003e\u003cp\u003eUse the TX-PCR1 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 TX-PCR1 is ideal to provide 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. If additional speaker lines need to be switched, the SLAVE terminal may be used to control additional TX-PCR1 modules or RDL ST-LCR1H High Power Logic Controlled Relays.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSwitching Functions Controlled by Speaker-Level Source\u003c\/li\u003e\n\u003cli\u003eInput Accepts Amplified Constant Voltage Signals\u003c\/li\u003e\n\u003cli\u003eSwitch-Selectable Input: 25 V, 70 V, 100 V\u003c\/li\u003e\n\u003cli\u003e25 Volt Input Also Accepts 8 Ω Inputs up to 75 Watts\u003c\/li\u003e\n\u003cli\u003eTransformer-Isolated Input\u003c\/li\u003e\n\u003cli\u003eFront-Panel Trimmer Provides Sensitivity Adjustment\u003c\/li\u003e\n\u003cli\u003eSignal Threshold LED Facilitates Sensitivity Adjustment\u003c\/li\u003e\n\u003cli\u003eFront-Panel Trimmer Provides  Release Delay Adjustment\u003c\/li\u003e\n\u003cli\u003eLED Indicates when Module is Triggered\u003c\/li\u003e\n\u003cli\u003eRelease Delay Adjustable from 3 to 25 Seconds\u003c\/li\u003e\n\u003cli\u003eOpen-Collector Output Active when Module is  Triggered\u003c\/li\u003e\n\u003cli\u003eSwitches on Paging or Any Other Amplified Audio Signal\u003c\/li\u003e\n\u003cli\u003e8  Amp DPDT Relay  Contacts for Switching Speaker Loads\u003c\/li\u003e\n\u003cli\u003eIdeal for Muting or Switching Primary Speakers During Paging\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable class=\"table1\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio Input\u003c\/td\u003e\n\u003ctd\u003eConstant-voltage speaker line, transformer-coupled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Level\u003c\/td\u003e\n\u003ctd\u003eSwitch-selectable 25 V, 70 V, 100 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Bandwidth\u003c\/td\u003e\n\u003ctd\u003e120 Hz to 7.5 kHz (-3 dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrigger Threshold\u003c\/td\u003e\n\u003ctd\u003e-40 dB to -15 dB (below 25 V, 70 V or 100 V), adjustable (single turn)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelease Delay\u003c\/td\u003e\n\u003ctd\u003e3 seconds to 25 seconds, adjustable (single turn)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Output\u003c\/td\u003e\n\u003ctd\u003eOpen collector @ 25 mA (SLAVE terminal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndicators (3)\u003c\/td\u003e\n\u003ctd\u003ePower (blue LED), Threshold (red LED), Triggered (green LED) \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitching Contacts\u003c\/td\u003e\n\u003ctd\u003e8 Amps maximum @ 250 Vac or 30 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitching Power\u003c\/td\u003e\n\u003ctd\u003e500 W (amplified audio signal;)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Requirement\u003c\/td\u003e\n\u003ctd\u003e24 Vdc @ 60 mA*, Ground referenced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e \u003cdiv class=\"spec_spacer\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"specifications\"\u003e*plus load current connected to SLAVE output\u003c\/div\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Type\u003c\/td\u003e\n\u003ctd\u003eCardboard Box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Dimensions\u003c\/td\u003e\n\u003ctd\u003e2 x 2 x 4 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.465 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWEEE weight\u003c\/td\u003e\n\u003ctd\u003e0.41 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTariff code\u003c\/td\u003e\n\u003ctd\u003e8536.49.0050\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":43895110926379,"sku":"RDL-TX-PCR1","price":185.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/3019\/5243\/files\/rdl-tx-pcr1-2__46137.1682436111.1280.1280.jpg?v=1775684058","url":"https:\/\/www.empirepro.com\/products\/rdl-tx-pcr1","provider":"Empire Pro","version":"1.0","type":"link"}
