Transmitter power supplies transfer 4-20 mA signals from transmitters in hazardous areas and

supply them with power. They deliver an electrical signal that is proportional to a measured value

such as temperature, pressure or flow from hazardous areas to safe areas. The power supply and

signal are transferred through the same conductors in 2-wire transmitters allowing only 4-20 mA

signals. The power supply and signal are isolated from one another in 3-wire transmitters allowing

for 0 mA signals. These mA signals can then be repeated on the safe side of the isolator or can be

converted to other usable signals such as voltage. SMART transmitter power supplies repeat the

transmitter current in addition to a digital signal, which is modulated onto the 4-20 mA signal.

SMART transmitters can be calibrated remotely. This allows the transmitter’s span and zero set point

to be modified in the safe area and information on scheduled maintenance or statistical data to be

accessed on-line. SMART transmitters normally operate in a 2-wire mode. This 2-wire connection

is usually interfaced with a hand-held terminal or a PC for data transmission or accumulation.

P+F SMART transmitter power supplies are shipped with terminal blocks to allow easy access to

communication leads. SMART transmitters from ABB, Bailey, Chessel, Edress+Hauser,

Fisher-Rosemount, Foxboro, Honeywell, Smar and Yokogawa have been successfully tested with P+F

isolators. Please note that some higher communication frequencies require use of the

KFD2-STC3-Ex1 or the KFD2-STV3-KFD2-STC3-Ex1. These isolators are rated for frequencies up to 40 kHz.

The SMART transmitter power supplies supply a 2-wire SMART transmitter within a hazardous area and transfer the analog 4-20 mA signal from the hazardous area to the safe area.

Digital signals which can be modulated onto the analog signal, can also be transmitted bidirectionally on the hazardous or safe side. Hand-held terminals can be connected as shown in the block diagram.

Hand-held terminals can be connected as shown in the circuit diagram. These isolators have BU and KF-STP-GN terminals with test probe access holes for the easy interface of hand-held terminals.

The SMART transmitter power supplies supply a 2-wire SMART transmitter within a hazardous area and transfer the analog 4-20 mA signal from the hazardous area to the safe area. This isolator is designed to provide a sink mode output on the safe area terminals.

The SMART transmitters are normally delivered with the BU and KF-STP-GN terminals. Connector jacks are integrated in these terminals for the connection of the handheld terminals.
