Output signal 4÷20mA + HART rev.5.1
Communication with the transmitter to check its configuration parameters is carried out via HART transmission
protocol and signal of 4÷20mA. For this purpose: KAP-03, KAP-03Ex communicator, HART/RS232 converter or
HART/USB Converter (APLISENS) or another converter, PC computer and Raport 2 programme can be used.
Resistance of power supply cables or resistors for communication, and output resistance of the power supply
can lead to voltage drops on the way from the power supply to transmitter terminals. Therefore, the maximum
resistance permitted to be included in a series circuit with the power supply should be calculated (Rmax load
resistance). The total resistance in the Ro current loop must be lower than this value to ensure the minimum
voltage on the terminals of the converter throughout the current loop operating range (up to 22.5 mA with regard
to HART alarms and communication).
The resistance necessary for communication (HART) min 240Ω
The maximum values of Rmax permissible load resistance for the supply voltage of the power supply (Usup[V]
DC) should be calculated based on the following formula:
Rmax[] =
When the Ro total load resistance in the current loop is given, the minimum supply voltage (Usup [V] DC)
required for the use of the power supply can be calculated likewise.
Usup[V] = Umin[V] + 0,0225 [A] x Ro[]
where:
Rmax – maximum permissible load resistance for a specific voltage of the power supply.
Ro – total resistance in the current loop
Usup – supply voltage
