RDL TX-PCR1 Paging Controlled RelayThe TX PCR1 is the ideal choice in many applications where switching needs to be controlled from a constant voltage amplified audio source.

The TX-PCR1 is the ideal choice in many applications where switching needs to be controlled from a constant-voltage amplified audio source. 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.

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 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.

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 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.

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

Use 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.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.
