Kongsberg Transmitter barrier
Single channel shunt diode safety barriers applied to make transmitter installations in hazardous areas intrinsically safe Kongsberg Maritime's DZ Barrier Units are designed to safely provide signal interface and power supply to our instrumentation located in hazardous area. The unit connects intrinsically safe 4-20 mA transmitters, and is can also be prepared for HART communication. The Transmitter Barrier is installed in safe area, designed to limit the amount of energy that could appear in an electric circuit that connects to instrumentation located in hazardous area. The DZ-110/U is a single channel shunt diode safety barrier, intended for energizing a 2-wire, 4-20 mA signal transmitter installed in hazardous area. Power supply: 24 VDC nom. (18 - 32 VDC)Input/output current: 0 to 22 mAATEX, IECEx and type approved The Zener Barrier is installed in safe area, designed to limit the amount of energy that could appear in an electric circuit that connects to instrumentation located in hazardous area. The DZ-120 is a single channel shunt diode safety barrier, intended for protecting a 2-wire, 4-20 mA/HART signal transmitter installed in hazardous area. Power supply: 24 VDC nom.
