Jumper Configuration
In order to work properly, the jumpers J1 and W1 located in the
IF303
main board must be correctly
configured (See Table 1.1 - Description of the Jumpers).
J1
This jumper enables the simulation mode parameter in the AI block.
W1
This jumper enables the local adjustment programming tree.
Table 1.1 - Description of the Jumpers
Power Supply
The
IF303
receives power from the bus via the signal wiring. The power supply may come from a
separate unit or from another device such as a controller or DCS.
The voltage should be between 9 to 32 Vdc for non-intrinsic safe applications.
A special requirement applies to the power supply used in an intrinsically safe bus and depends on
the type of barrier used.
Use of
PS302
is recommended as power supply.
Input Wiring
The
IF303
accepts up to three current inputs in the range 0-20 mA or 4-20 mA. The three inputs
have a common ground and they are protected from reverse polarity signal. The inputs should be
connected as per Figure 1.6 - Input Wiring.
