Product Precautions
- HIMA F3238 evaluates field switching signals in intrinsically safe circuit arrangements. The module and the connected field devices must be selected as a complete approved loop.
Product type: Eight-channel initiator input module
Signal sources: NAMUR proximity switches or resistor-network contacts
Circuit function: Intrinsically safe input evaluation with SC/OC diagnostics
Signal sources: NAMUR proximity switches or resistor-network contacts
Circuit function: Intrinsically safe input evaluation with SC/OC diagnostics
F3238 evaluates eight inputs from NAMUR proximity switches or contacts equipped with a resistor network. HIMA identifies short-circuit and open-circuit diagnostics for this initiator-input design. The HIQuad product classification includes SIL 3 capability, while the achieved safety function still depends on the configured system, approved revision and field loop.
The IECEx circuit specification gives a 24 V DC supply circuit UB1 with −15%/+20% tolerance and a separate 5 V DC UB2 supply with ±10% tolerance. The certified ambient range is 0–60 °C. These supply values belong to the module circuits and must not be confused with the intrinsically safe field-loop output limits.
The intrinsically safe control circuits have Uo 9.9 V, Io 15 mA and Po 38 mW. Permitted external capacitance and inductance depend on the gas or dust group and whether both are considered together; the higher separate maxima cannot simply be combined. Certified switches or contacts may be located in hazardous areas from Zone 0 when the complete installation meets the applicable approval conditions.

HIMA F3238 technical reference
Prepared by Apter Power - PDF, 5 pages, 95.2 KB. F3238 is an eight-channel initiator input module. Intrinsic-safety values apply to the certified circuit arrangement and its external capacitance/inductance conditions; module identification alone does not establish a complete safety-loop approval. -
HIMA F3238 installation planning guide
Prepared by Apter Power - PDF, 5 pages, 96.5 KB. Identity, configuration, connection and controlled acceptance planning.
F3238 is an eight-channel initiator input module. Intrinsic-safety values apply to the certified circuit arrangement and its external capacitance/inductance conditions; module identification alone does not establish a complete safety-loop approval. The planning guide is prepared by Apter Power; apply the complete manufacturer instructions and the stated applicability boundaries.
System and supply context: F3238 is an eight-channel initiator input module. Intrinsic-safety values apply to the certified circuit arrangement and its external capacitance/inductance conditions; module identification alone does not establish a complete safety-loop approval. Accessories are included only when itemized in the quotation.
Platform applications: The following applications describe HIMA HIQuad functions. Match the complete F3238 identity to the installed system before selecting a replacement.

-
NAMUR switching signals
Evaluate suitable proximity-switch states through the approved initiator-input circuit. -
Resistor-network contacts
Use contacts with the required network so that signal states and line faults can be distinguished. -
Hazardous-area field loops
Connect certified field devices using entity parameters and wiring conditions appropriate to the location. -
Safety-system maintenance
Retain the module revision, channel assignments and validated safety application during replacement.
Prepare F3238 against the installed configuration and applicable HIMA instructions. Plan isolation and the resulting interruption of system operation before replacement.
Check complete approval
Match module revision and the complete system approval before installation.
Match field devices
Use the correct NAMUR sensor or contact resistor network for the intended loop.
Review entity parameters
Check Uo, Io, Po and the applicable external capacitance and inductance limits together.
Separate supply circuits
Distinguish the 24 V and 5 V supply circuits from the intrinsically safe field connections.
Respect ambient conditions
Maintain the certified 0–60 °C module ambient range and approved enclosure conditions.
Validate safety behavior
Perform the authorized channel and fault-response validation before returning the safety function to service.
