More Information

Overview Manuals Loop Interface Hazardous Areas Rack Integration Approval Scope

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.
Description
HIMA F3325 is a six-channel intrinsically safe transmitter supply unit that links approved Ex i field circuits to F6221 analog input processing in a HIQuad installation.

Each F3325 channel provides the defined supply-and-signal path needed by the associated analog input arrangement, while galvanic separation maintains the boundary between intrinsically safe and non-intrinsically safe wiring.

The F3325 hardware belongs in a vertically mounted 19-inch subrack outside the potentially explosive area. Cabinet layout must preserve heat dissipation and the separation distances required for the two circuit classes.

During commissioning, F3325 field wiring is terminated with the approved conductors and ferrules, then the intrinsic-safety documentation for every connected transmitter loop is checked as a complete circuit.

Technical notes
F3325 must remain outside the hazardous area, with Ex i and non-Ex i conductors routed to preserve the required separation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can F3325 be mounted inside the hazardous area?
No. F3325 is installed outside the potentially explosive area while its approved intrinsically safe circuits extend to the field devices.
Which analog input module is paired with F3325?
F3325 is designed for the F6221 analog input arrangement, so another module must not be substituted without an approved design basis.
Why must F3325 Ex i and ordinary wiring remain separated?
F3325 depends on galvanic separation and compliant conductor routing to preserve the intrinsic-safety boundary of each transmitter loop.
How should stranded conductors be prepared for F3325?
Terminate stranded F3325 wiring with suitable ferrules so individual strands cannot compromise spacing or connection security.
What mounting direction is required for F3325?
F3325 is installed vertically in the supported 19-inch subrack, with cabinet space reserved for heat dissipation.
Can six unrelated transmitters share one F3325 channel?
No. F3325 provides six separate channels, and every transmitter loop uses its assigned protected supply-and-signal path.
What must be reviewed before connecting a replacement transmitter to F3325?
For F3325, confirm the complete Ex i loop parameters, approved components, cable characteristics, and association with the correct F6221 input.
