Our power packs provide the DC power supply for 2-wire transducers and transfer the measured variable unchanged to the electrically insulated output. These differ in their capability for FSK communication, the number of supply circuits and their open or short-circuit monitoring and signalling.
Power supply units designed for FSK communication are used in conjunction with "intelligent" 2-wire transducers which are capable of dialogue and operation according to the FSK principle and the HART or user-specific protocol.
The series also includes "intrinsically safe" versions [EEx ia] IIC with an intrinsically safe input. These operate in conjunction with intrinsically safe 2-wire transducers located in explosion hazard areas.
