9160 series Ex i transmitter power supply units can be used for the intrinsically safe operation of two- and three- conductor transmitters or intrinsically safe mA sources such as four- conductor transmitters. The unit allows HART signals to be transmitted in both directions. The portfolio includes one- and two- channel units and a variant for signal duplication. Special versions are available for higher output voltages and SIL 3.
