Product Description
42100 is a safety‑related logic function module of German HIMA Planar4 series. It provides 4 pieces of 5‑input hardware AND‑gate elements, certified for SIL4 according to IEC 61508, designed for Safety Instrumented Systems (SIS). Continuous self‑monitoring is implemented; fault status is indicated via ERR signal and relay contact alarm output. Fast switching response with 24 VDC power supply. Euro‑card rack‑mount form factor. Obsolete OEM unit, used for maintenance and spare‑part replacement of legacy Planar4 safety systems.
