Features:
- Six independent intrinsically safe transmitter-supply channels
- Designed for the F6221 analog input arrangement
- Galvanic separation between Ex i and ordinary circuits
F3325 brings six hazardous-area transmitter loops into a HIQuad analog input assembly while keeping the interface hardware on the safe side of the installation.
Each field loop retains its own supply-and-signal path to the associated F6221 input; compliant wiring and loop documentation preserve the intrinsic-safety boundary.
The unit mounts vertically in a 19-inch subrack outside the potentially explosive area, with cabinet space reserved for heat removal and separated conductor routing.
HIMA F3325 six-channel intrinsically safe transmitter supply unit can be quoted by Apter Power together with the official HIMA references needed to review the complete Ex i loop arrangement.

F3325 transmitter-loop organization
- Six circuits: The unit presents six individually defined supply paths for approved transmitter loops.
- Input pairing: Each field channel is associated with the F6221 analog input arrangement used by the HIQuad system.
- Signal boundary: Galvanic separation keeps intrinsically safe conductors isolated from ordinary rack-side circuits.
- Complete loop: The transmitter, barriers, cable, and F3325 channel must be assessed together as one Ex i circuit.
F3325 intrinsic-safety boundaries
- Safe-side mounting: F3325 is installed outside the potentially explosive area.
- Ex i testing: Intrinsically safe circuits withstand the dielectric test level of at least 1000 V AC.
- Ordinary circuits: Non-intrinsically safe sections use the higher test level of at least 1500 V AC.
- Separation practice: Cable routing must preserve the approved distinction between the two circuit categories.
F3325 mechanical integration
- Subrack format: The module operates in the specified 19-inch HIMA rack environment.
- Vertical position: The installation orientation is vertical so ventilation follows the required arrangement.
- Thermal clearance: Cabinet design must allow heat produced by the interface electronics to leave the rack.
- Terminal preparation: Stranded wires are finished with suitable ferrules before connection.
F3325 certified module scope
- Module function: HIMA lists F3325 as a six-channel intrinsically safe supply module for the F6221 analog input module.
- Signal circuits: The approved module description covers 0/4...20 mA Ex i channels associated with the F6221 arrangement.
- Interaction class: The HIQuad X revision list places F3325 among the non-interacting modules.
- System boundary: The type-approval scope includes F3325 as HIQuad X hardware for safety and critical-control configurations.
