More Information

Overview Manuals Loop Architecture Fault Response Output Validation Application
  • Two independently isolated analog output channels
  • Source- and sink-mode current-loop operation
  • Integrated diagnostic tests and safety shutdown

F6705 is used where the safety controller must command analog loop current while continuously checking the converter and output path for faults.

The decisive configuration choice is source versus sink operation, because that choice changes the external supply arrangement and the mechanism used to achieve the safe de-energized state.

After replacement, each channel should be driven through controlled current values while the connected load, diagnostic feedback and final safe-shutdown action are verified together.

Availability, condition, price, and shipping time for F6705 are confirmed during quotation.

  • Document source or sink operation before disconnecting the module
  • Preserve loop-supply polarity and the complete current path
  • Confirm the connected device and cable remain within the approved burden
  • Verify that source-mode faults invoke the integrated shutdown
  • Provide the approved external supply shutdown for sink operation
  • Retain the documented software evaluation for loop faults
  • Command controlled values across the configured output range
  • Measure actual loop current at the connected load
  • Prove diagnostics and the final safe-state response before release
  • Safety-related analog positioning commands in emergency shutdown systems
  • Isolated current-loop control in high-integrity process protection
  • Analog final-element demand signals in burner and boiler protection
Description
F6705 provides two safety-related analog current outputs, with each channel galvanically isolated. It supports current-source or current-sink operation and is approved for SIL 3 applications in the HIQuad architecture.

Automatic tests read back the output signals, check D/A converter linearity, detect crosstalk and verify the integrated safety shutdown. In source mode, detected faults de-energize the affected module through that shutdown path.

Sink-mode applications require a project-controlled external shutdown of the loop supply and the documented HZ-FAN-3 evaluation. Replacement must preserve the operating mode, loop burden, wiring and programmed fault response.

Technical notes
HIMA F6705 requires matched revision, source-or-sink wiring, loop burden and programmed shutdown behavior; sink operation without the approved external supply shutdown creates a serious safety-selection risk.

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.
How can a buyer confirm whether HIMA F6705 is wired as a current source or sink?
Review the field drawing and loop supply arrangement, then compare the installed wiring with HIMA's source- and sink-mode diagrams before disconnecting any conductor.
What safe-state difference matters between HIMA F6705 source and sink modes?
In source mode the integrated shutdown can de-energize a detected fault. Sink mode needs an external safe shutdown of the loop supply controlled by the approved application logic.
Why can HIMA F6705 shut down after an open output loop?
HIMA states that source mode cannot distinguish an external open circuit from certain internal faults, so the module may enter the safe de-energized state.
What should be backed up before replacing HIMA F6705?
Record the source or sink mode, channel scaling, loop supply, burden, cable route, safe value, alarm limits and HZ-FAN-3 handling where used.
Can HIMA F6705 drive any four-to-twenty milliampere load?
No. Confirm total loop burden, line resistance, supply voltage and connected device input requirements against the documented limit for the selected operating mode.
How should HIMA F6705 be tested without disturbing the process?
Isolate or simulate the final device under the approved test plan, command controlled values across the range and verify loop current, readback, diagnostics and safe shutdown.
Can HIMA F6705 be replaced by F6706?
Do not substitute by channel count or current range alone. Confirm the safety approval, isolation, fault reaction, operating mode, software handling and hardware revision for F6705.
