Installation cable, with common copper shield,

Cables are designed to form information field buses, connect sensors with digital frequency-modulated signal, 4-20 mA signal, on the interface HART, RS485, RS482, RS422 and other interfaces requiring the use of "twisted pair (triple, quadruple)" as a channel for receiving / transmitting data, as well as for the transmission of signals to the control equipment and are used for remote control of actuators and for interdevice connection. Operating nominal AC voltage up to 660 V inclusive, frequency up to 1 MHz or DC voltage up to 1000 V inclusive.
