摘要:
A radio unit for a plant of process automation technology. The radio unit has a power circuit, which serves to derive first and second supply voltages from a voltage source, wherein the power circuit has a first output, via which the first supply voltage is tappable to serve for driving an operating electronics of the radio unit, wherein the power circuit has at least a second output, via which the at least a second supply voltage is tappable to serve for driving at least one field device connectable to the second output.
摘要:
A method for setting energy supply parameters of a field device electrical current supply module. The field device electrical current supply module is connected, in such case, exclusively to one field device. The connected field device can be supplied electrical energy by the field device electrical current supply module. In the method, a field device type of the connected field device is identified first by the field device electrical current supply module. Then, a parameter setting of at least one energy supply parameter of the field device electrical current supply module is automatically read out from a database and this is loaded into the field device electrical current supply module.

摘要:
An automation technology, autarkic, field device, which is connected via two connecting terminals to an I/O module. The I/O module is embodied as a 4-20 mA/HART I/O module. The I/O module is associated with a controllable energy source via which the field device is supplied with energy. An electrical current measuring unit is provided which ascertains the electrical current supplied by the energy source. In the I/O module, internal resistors are provided, across which occurs in each case a voltage drop dependent on the flowing electrical current. A control unit is provided, which operates the energy source in such a way that a predetermined terminal voltage is supplied on the connecting terminals for powering the field device.
