More Information

Overview Manuals OR Logic Planar4 Integration Commissioning Checks Product Applications

Features:

  • Eight independent OR logic functions
  • Two inputs assigned to each OR function
  • Hardware revision 21 listed valid in the HIMA Planar4 revision record
Logic function: Each channel group combines two input conditions through a hardware OR function, allowing either documented input path to assert the corresponding logic result.

Safety platform: The module belongs to HIMA Planar4, a platform documented for safety-related applications up to SIL 4 when used within the approved system design.

Configuration control: Cabinet drawings, slot position and hardware revision remain the authoritative references for mapping each OR function to field interlocks.

Apter Power supports HIMA 42300 Planar4 OR Module documentation, quotations, procurement and rack-configuration guidance.

  • Eight separate OR functions are provided on the module.
  • Each OR function receives two input conditions.
  • Either asserted input can activate the documented OR result.
  • Field interlock meaning depends on the cabinet logic drawing.
  • The module is installed as part of a HIMA Planar4 safety system.
  • Hardware revision 21 is the revision recorded for type 42300.
  • Slot position and rack wiring must match the installed Planar4 documentation.
  • System safety capability depends on the complete approved architecture, not one module alone.
  • Verify both input paths for each used OR function.
  • Compare output response with the cabinet cause-and-effect logic.
  • Record the module type, hardware revision and slot before removal.
  • Investigate external wiring and permissives before attributing a failed interlock to the module.
  • Emergency shutdown logic that combines two documented trip conditions.
  • Burner or boiler protection circuits using hardware OR interlocks.
  • High-integrity pressure protection and primary shutdown architectures.
  • Time-critical Planar4 safety circuits retained in existing plants.
Description
42300 is a HIMA Planar4 safety-related OR module containing eight independent OR functions, with two inputs assigned to each logic function.

42300 is listed by HIMA with hardware revision 21 and a valid product status in the Planar4 revision record, within a platform documented for safety applications up to SIL 4.

Apter Power can provide quotations, official Planar4 documentation and rack-level application review for 42300 without adding unsupported diode or electrical ratings.

Technical notes
For a 42300 service check, trace both inputs and the resulting output for the affected OR function against the cabinet drawing. Confirm the installed Planar4 slot, hardware revision and rack wiring before exchange. Do not reuse the former page's diode, fuse, voltage or recovery-time values because HIMA did not substantiate them for this exact type.

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 should an inactive output be investigated on HIMA 42300?
Check both assigned input conditions, the rack wiring and the cabinet logic drawing. An open field circuit or missing permissive can prevent the expected OR result even when the module is healthy.
What should be recorded before removing HIMA 42300?
Record the slot, type marking, hardware revision 21, connector orientation and every field-wire designation so the eight OR functions can be restored to the correct interlocks.
Can one asserted input operate a function on HIMA 42300?
Yes. Each documented logic function has two inputs arranged as an OR, so either asserted input can produce the corresponding logic result when the system wiring is correct.
Why must cabinet drawings be used when testing HIMA 42300?
The module provides generic OR functions, but the drawings define which plant conditions and outputs are assigned to each function. Testing without that mapping can misinterpret normal behavior.
Does the SIL 4 platform statement make HIMA 42300 a standalone SIL 4 device?
No. The statement applies to the documented Planar4 safety-system architecture. The achieved safety integrity depends on the complete approved design, application logic, wiring and proof testing.
What should be excluded from a HIMA 42300 service decision?
Do not rely on the former page's diode current, reverse-voltage, fuse or recovery-time claims. They were not supported by the exact-model HIMA records used for this revision.
