Terminals in the transmitter housing provide connections for signal cables.

The 3300 transmitter is loop-powered and operates with power supplies ranging from 11 to 42 VDC. For Intrinsically￿￿￿￿￿()(￿%￿(￿￿￿￿￿0,,￿)￿￿￿Safe output￿￿￿"the￿￿supply￿ voltage must be within 11 to 30 VDC. For Explosion Proof/Flame￿Proof￿the supply voltage must be within 16 to 42 VDC. F￿ - ￿￿￿

The maximum current loop resistance can be gained from the following diagrams:
