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.
- Can be used universally for two- and three-conductor transmitters and mA sources (four-conductor transmitters)
- high degree of accuracy
- standard variant can be used up to SIL 2, special variant up to SIL3 (IEC/EN 61508)
