RDL AV INTERFACES - TX Series

RDL TX series is a range of small enclosed “black boxes” offering a simple, high quality solution to temporary or permanent interfacing, communication and distribution problems especially in theatre, PA and broadcast.

All TX series modules measure 76 x 30 x 36mm. They are the same 'family' as the Stick-on series, but are devices where the ST-type housing, with screw terminal connections, is unsuitable, eg. where the use of connectors is required.

Included accessories: All models are supplied with a data sheet with installation details.

CONTROLLED RELAYS


TX-PCR1 Paging Controlled Relay

With switch selecting inputs of 25/70/100V and up to 75w, 8ohm input when on 25V mode, this controlled relay triggers when any program material/paging source is applied. An ‘open-collector’ slave output is included to control other modules or equipment along with a DPDT (double-throw, double-pole) switching relay.

Input sensitivity can be adjusted using a trimmer pot with the sensitivity trigger being 30dB below the switch-selected constant voltage. A red LED illuminates when any audio level exceeds the set trigger threshold. The delay is adjustable from 3 to 25 seconds via a trimmer positioned on the front panel. All inputs and outputs are via screw terminal block.
Supply 24V DC, 60mA.


TX-VCR Video Controlled Relay

A single pole changeover relay activated by the absence of a valid video signal on the loop through video signal. While a valid (video sync) signal is present the relay contact is closed, and when the signal is lost, it opens. Both normally closed and open contacts are provided so it can be configured as a video detection or video loss indicator. Sync and fault LED’s are also provided. Input and outputs on BNC connectors.
Supply 12-33V DC or 12-24V AC, 75mA.
