FOUNDATION fieldbus H1 (FF H1) supplies power and transmits communication digitally between host systems such as a DCS or a PLC and field instrumentation.
The basic power supplies provide power to single segments. The power supplies are built into 20 mm wide housings, which snap on the DIN-Rail or power rail. Through the power rail, they can be connected to redundant bulk power. A standard feature is an overall passive design such as impedance generation and lowest power dissipation. They are ideal power supplies for small installations or test laboratory environments.
Most importantly the power supply design leads to significant savings. More room in the cabinet and reduced requirements for cooling often removes the need for fans in the cabinet.
The power supply module features full galvanic isolation, passive impedance generation, and low heat dissipation. This is the most common choice for fieldbus segments. The output voltage is set so that the most common explosion protection concepts can be designed in combination with suitable fieldbus couplers.
