HIMA F60MI 2401

Technical Specifications

Safety certification SIL 3 (IEC 61508 / IEC 61511), PL e; total 24 configurable channels; channel mode selectable digital‑input or analog‑current‑input; transmitter supply output 8.2 VDC or 26 VDC switchable per channel‑group; power‑supply 19.2‑28.8 VDC; operating temperature ‑25 °C ~ +70 °C; galvanic channel‑to‑bus isolation; IP20 protection; weight 0.6 kg.

Functional Features

Per‑channel wire‑break and short‑circuit fault‑diagnosis; NE43 compliant analog‑input fault‑detection for transmitter open‑circuit / short‑circuit; short‑circuit‑protected transmitter‑supply outputs; status LED for module health and channel faults; parameter configuration and diagnostics via SILworX engineering‑tool; fits HIMatrix F60 subrack back‑plane.

Application Scenarios

Petrochemical SIS safety‑instrumented‑systems, oil‑gas emergency‑shutdown systems, burner‑management‑systems, turbine safety monitoring, distributed safety‑I/O stations in process‑industry hazardous‑Zone 2 areas.

Performance Parameters

Analog‑input 4‑20 mA measurement accuracy ±0.15 % full‑scale; digital‑input compatible with safety dry‑contacts and Namur‑type proximity‑sensors; response‑time for each channel less than 12 ms.

Material Composition

Euro‑card circuit‑board assembly, metal front‑panel, plug‑in spring terminal‑blocks, conformal‑coated industrial‑grade printed‑circuit‑board.

Structural Features

Standard Euro‑card subrack‑plug‑in module; front‑panel with status LED indicators; removable plug‑in terminal connectors for field‑wiring; rear edge‑connector for F60‑system back‑plane bus insertion.

Working Principle

Each channel hardware circuit can be configured as digital‑input or analog‑current‑input mode; digital‑input reads contact‑state and performs circuit‑fault‑checking; analog‑input samples 4‑20 mA loop‑current and detects transmitter‑loop faults; all processed digital‑diagnostic‑data transferred over back‑plane bus to HIMatrix safety‑controller.

Installation Requirements

Insert module into designated slot of HIMatrix F60 subrack; fasten front‑panel retaining screws; use SELV‑PELV isolated 24 VDC power‑supply; use shielded twisted‑pair cables for analog‑transmitter loops; separate signal‑cable routing away from high‑power‑cables; cabinet must maintain natural ventilation cooling.

Usage Precautions

Configure channel type (digital‑input / analog‑input) via SILworX before commissioning; confirm transmitter‑supply‑voltage setting matches connected field‑device specification; replace complete unit when hardware‑fault occurs; do not remove module from powered‑on subrack unless system‑maintenance procedure permits; observe maximum cable‑length limits for Namur‑sensor and analog‑loop wiring.
