TX7240 Loop Relay Module TX7240 Loop Relay Module

The unit manufactured base on the requirement of EN 54 part 18, European Standard. The unit is aesthetically pleasing with unobtrusive design that will complement modern building designs and its plug-in type assembles make installation and maintenance more convenient to the installer. The unit is compatible to the TX7004 Analogue Intelligent Fire Alarm Control Panel, produced by single manufacture T&A, to avoid addressable communication compatibility problem.

Overview

TX7240 loop relay module uses DC24V power supply, through the internal electrical isolation circuit, realize the input bus signal and the output bus signal isolated real-time transmission, output standard bus waveform. The loop relay module can improve the anti-interference ability of the bus, and has the function of extending the communication distance of the bus. The bus signal is mainly used in the field of external interference distortion or need to extend the communication distance of the bus.

Feature and Benefits

• EN54-18:2005 Compliance Built- in MCU processor

• Input bus, the output bus signal between the electrical isolation, electromagnetic interference has a good inhibitory capacity, stable and reliable work Input Fire or Supervisory signal configuration

• LED status indicator

• To correct the bus signal, the output standard bus waveform

• Fast intelligent bus output short circuit judge function, bus output short circuit protection function; after the bus is normal, it can recover the bus output in time

• Aesthetically pleasing design
