Product Description:

The 7XV124.50-51 is a remote valve terminal controller manufactured by B&R Automation. With 24 high-side driver outputs, it is made to provide reliable digital output control. The device is made to meet certain operational and safety standards and works with industrial automation systems.

With a range of ±25%, the 7XV124.50-51 remote valve terminal's switching voltage is 24 VDC. It can handle a switching frequency of up to 100 Hz and an output current of up to 0.1 A per channel. The output circuit type is source, which means it can work with a wide range of loads. Overload diagnostics are built into the product through software and LED lights that watch for short circuits, overloads, and high temperatures. An M12 interface is used for the bus link, and a 25-pin DSUB connector can connect to 24 valves to the remote valve terminal. It can be mounted either horizontally or vertically, and it can work in temperatures from 0C to 55C. According to EN 60529. It is certified by UL, cULus E115267, ATEX Zone 2, II 3G Ex nA IIA T5 Gc, and nA IIA T5 Gc.

The <<7XV124.50-51 remote valve terminal is 62 mm tall, 70 mm wide, and 30 mm deep, and it weighs 125 g. Status lights show how the system is working and the power source. The delay between 0 and 1 is usually 100 µs and can be up to 150 µs. The type of digital output is a high-side driver (source), which makes wiring easier and safer. Short circuit, overload, and overtemperature safety are all built into the output. The design of the controller makes it safe and easy to handle multiple valves, and it also has diagnostic features that make operations more reliable.
