Master unit receiver, EU frequency 868.3 MHz, 8 transistor outputs

Wireless pushbutton with sub-GHz band combining wireless reliability and ease of use in a working environment. Sub-GHz band to reduce interference and ensure better signal propagation in hard-to-reach areas. Visualization of wireless transmission impedance due to damage or noise, thanks to the master unit error output. Visualization of slave button reception status via reception confirmation LEDs. Transmission distance independent of slave button transmission position. Configuration visualization using PC tools to avoid ID registration errors. Signal quality visualization on screen and in operating environments using PC tools. 8 outputs focused on decentralized control. Self-powered to eliminate battery replacement and enhance safety and energy saving with the slave button. Ease of use of buttons thanks to the slave button shape.
