4.1.9 Analog inputs
Rex supports two high precision 4-20 mA analog inputs. Using the
analog inputs requires that the transmitter is equipped with the
Transmitter Interface Card (TIC).
Analog Input 1 may be used to connect up to 3 HART Slaves (requires
Multi FCC card). See 4.1.11.
Figure 4-7. Connection of analog input instruments to the Rex Junction
Box.
The Analog Inputs are identified automatically by the software. The TIC
board must be detected before this function is enabled.
Analog inputs are connected to socket X12 for intrinsically safe
connections in the Rex Junction Box. For further information on how to
connect analog inputs see the
TankRadar Rex Installation Manual .
Note! Analog inputs can only be enabled at factory.
