IV. Consideratio Clavis: Solutiones Electromagnetic Compatibility (EMC)
In ambientes industrialis cum numerosis dispositivis electricis et duri electromagnetic ambientes, interferentia electromagneticalis est causa principalis malfunctionis vel failure temporis relatorum. Ad securandum fidelitatem systematis, implementari debent sequentes measures EMC:
- Design Internus Producti: Preferre solutiones circuiti integrati dedicati cum excellente perfomantia EMC. Ipsum productum debet incorporare intrinsecos circuitos filtrandi potentiae, technologia isolationis signalis, et componentes suppressionis transientis (e.g., TVS diodes) ad suppressendam conductionem interferentiae ab lineis potentiae et signalis.
- Installation et Wiring Systematis:
- Shielding et Grounding: Control cabinets debent recte groundari. Input/output signal lines temporis relatorum, praecipue long-distance transmission lines, debent usare shielded twisted-pair cables cum stratum shielding single-end groundari.
- Separate Wiring: Separare lineas potentiae (AC 380V) ab lineis controlis (DC 24V) et signalis, retinendo certam distantiam ad reducendum interferentiam causatam per inductionem electromagneticam.
- Absorption Protection: Connect absorption circuits (e.g., RC absorption circuits or freewheeling diodes) in parallel with relay coils and inductive loads (e.g., contactors, solenoid valves) to suppress reverse electromotive force impacts.
V. Guidelines Selectionis et Usus
- Modus Operationis: Determinare si requiritur on-delay, off-delay, vel alii genera complexa.
- Range et Accuratia Dilationis: Ex requisitis processus, determinare tempus dilationis necessarium et error permittendus, et eligere productum cum appropria base temporis et methodo setting.
- Potentia Supply Voltage: Confirmare level voltage circuiti controlis (AC/DC, 24V/110V/220V).
- Capacitas Contactuum Output: Verificare capacitas voltage et currentis contactuum output relatorum (e.g., 5A/250VAC) ad securandum quod possint drive subsequentes contactores vel onera.
- Factores Ambientales: Considerare loci temperaturam, humiditatem, vibrationem, et niveles interferentiae electromagnetic, et eligere producta cum correspondentes ratings protectionis et perfomantia EMC.
