Unauthorized access prevention device

UPND is designed to control unauthorized access to automated control systems, as well as to switch the remote control circuit of the starter by means of a specialized mechanical key. Access control is carried out by reading data from Rfid tags. The switching of the stop circuit is performed by a specialized key. The power to the UPND is supplied from an intrinsically safe power supply. Communication with the control system is carried out via a wired RS485 interface.Request price >
