      Information

      Information

      Overview Manuals Common Applications Product Precautions
      HIMA F3237 is an eight-channel safety-related input module for NAMUR proximity switches and resistor-wired sensor circuits. The manufacturer sheet specifies automatic input tests and line-break and short-circuit monitoring with defined current thresholds.
      • Eight input circuits accept documented proximity-switch or resistor-wired sensors.
      • 0 and 1 current bands are 0.35–1.2 mA and 2.1–6.0 mA.
      • Wire break is recognized at or below 0.28 mA; short circuit at or above 6.5 mA.
      • Automatic tests include switching, crosstalk and input-filter checks.

      Match the front plug, channel mapping and installed sensor circuit to the approved HIMA safety application.

      Important Notice: Verify Z 7108 / 3237 / C.. and the actual sensor-line current before replacement.

      HIMA F3237 Technical Reference (PDF)HIMA F3237 Installation & Commissioning Guide (PDF)

      The first PDF presents exact F3237 current bands, fault thresholds and interfaces; the second provides separate installation and acceptance checks. Both use the original HIMA F 3237 (9912) data sheet as their technical basis.

      NAMUR proximity inputs
      Read approved proximity-switch circuits using the documented current bands.
      Resistor-wired sensors
      Connect specified resistor-wired field circuits with the approved channel map.
      Line diagnostics
      Detect wire break and short circuit using the HIMA current thresholds.
      Redundant sensing
      Apply the original manufacturer redundant-connection diagram where engineered.
      For HIMA F3237, verify the installed sensor type, current bands and Z 7108 front-plug variant before changing any safety input.
      1
      Record the complete F3237 marking and revision.
      2
      Use the site-approved safe-work and isolation procedure.
      3
      Identify each proximity or resistor-wired sensor circuit.
      4
      Confirm 0- and 1-signal current bands at all eight inputs.
      5
      Check the Z 7108 / 3237 / C.. front-plug variant.
      6
      Verify line impedance and cable length for the conductor.
      7
      Test wire-break and short-circuit diagnostics under control.
      8
      Complete the approved eight-channel safety proof test.

      Technical notes

      Verify the full F3237 marking, Z 7108 / 3237 front-plug variant, eight channel pairs, sensor type and current bands. Test line-break and short-circuit response in the approved safety application; do not infer compatibility from another eight-input card.

      FAQS

      • What is HIMA F3237?
        An eight-channel safety-related input module for proximity-switch or resistor-wired sensor circuits.
      • What are the 0-signal and 1-signal current bands?
        The HIMA sheet gives 0.35–1.2 mA for 0 and 2.1–6.0 mA for 1.
      • When does it detect a wire break?
        The documented wire-break threshold is at or below 0.28 mA.
      • When does it detect a short circuit?
        The documented short-circuit threshold is at or above 6.5 mA.
      • Which front-plug marking must be checked?
        Verify the Z 7108 / 3237 / C.. front-plug variant against the installed unit.
      • What sensor supply voltage is specified?
        The HIMA sheet specifies 8.2 V for the sensor supply.
      • What line length is specified?
        The sheet lists up to 1000 m with a 0.5 mm² conductor, subject to the stated line impedance.
      • Are the LED functions tested automatically?
        No. The original sheet says the LED functions are not automatically tested.
