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.
