Application Information
Bulletin 937 Intrinsically Safe Barriers transmit signals
between field devices and a process control system/control
system.
They are suitable for the connection of field devices used in
potentially explosive atmospheres. Safe field circuits for
these devices are intrinsically safe and are galvanically
isolated from non-intrinsically safe circuits. establish an
electromagnetic separation between the potentially
explosive atmospheres and the safe areas in a system.
The
transmitter supply coverters are measuring units that
provide an output signal consisting of a unit current signal
(4 mA ... 20 mA). A transmitter power supply provides a
transmitter with power and processes the
current signal.
The transmitter supply conerter translates a fully
parameterizable partition of input signal into a
proportional output current (4ma...20mA)
This output signal will be transferred to indicators or to
analog inputs on the process control system/control
system, for example. Both relay outputs of the transmitter
supply converter can monitor two fully parameterizable
trip values of the input signal.
