Institutiones in Locis Periculosis – Suitable for Class I Division 2 and ATEX/IECEx Zone 2 environments when mounted in appropriately rated enclosures
8 Sinking DC Inputs – Accepts 24 V DC signals from sourcing field devices with 2.0 mA minimum on-state current
Wide Operating Voltage Range – Supports 10…31.2 V DC, accommodating variations in field power supplies and cable voltage drops
Programmable Input Filtering – Octo tempora filtrationis selectibilia (0.25 ad 32 ms) per bitos configurationis ut repellantur oscillationes contactus et rumores electrici
Coniunctio Flexbus Backplane – Interfacit ad retroplanum I/O per conectorum Flexbus pro commutatione rapidissima datorum cum adaptatore vel modulis proximis
Approbationes pro locis periculosis – Certificatum est pro Class I Division 2 Gruppi A–D, ATEX/IECEx Zona 2 (Ex ec IIC T3 Gc), et CCC Ex pro diffusionibus globalibus
Optiones flexibiles connexionis – Suffragat dispositiva campestria bi- et tri-filari (interruptores limitis, sensoria proximitatis, sensoria photoelectrica) cum numeratione clara terminalium
Compacta Modularis Forma – Occupat unicum locum in basi terminali FLEX I/O, maximizans densitatem tabulae et simplificans expansionem systematis
Indicatores LED diagnosticorum – LED status singularum intrationum praebent indicationem visualem in tempore reali statuum ON/OFF singulorum canalis
Operatio in Latis Temperaturis – Operat ab –20°C usque ad +55°C, idoneum pro ambientibus industrialibus exigentibus
Clavis Terminalis Basiata – Clavis (positio 2) certificat installationem moduli rectam et impedit insertionem impropriam
Densitas Alta In/Out in Spatio Parvo – Design octopunctus praebet numerum canalis efficacem per scabellum, minuens pretia tota apparatus systematis et spatii tabulae necessaria comparata cum alternativis minoris densitatis.
Approbationes Globales pro Locis Periculosis – Cum certificationibus c-UL-us Classis I Divisio 2, ATEX/IECEx Zona 2 (Ex ec IIC T3 Gc), et CCC Ex, 1794-IB8 simplificat designum systematis pro projectis internationalibus quae requirunt conformitatem ad plures normas securitatis.
Compatibilitas Adapterum Flexibilis – Operat sine difficultate cum latissimo ambitu adapterum communicationis—Remote I/O, ControlNet, DeviceNet, EtherNet/IP, et PROFIBUS—permittens integrationem in fere omnem architecturam rete I/O distributam.
Filtratio Ingressus Configurabilis ab Usu – Octo tempora filtrationis selectibilia permittunt adustam adaptationem ad necessitates applicationis specificas, minuendo falsos activationes ex contactu oscillante aut rumore electrico sine detrimento velocitatis responsionis.
Supportus bifilaris et trifilaris – Accipit utrumque dispositivum campi bifilare (signum + alimentatio) et trifilare (signum + alimentatio + communis), praebens flexibilitatem pro typis sensorum mixtis in unico modulo.
Robustus Design Industrialis – Certificatus pro operatione inter –20°C et +55°C, umiditate 5–95%, et altitudinibus usque ad 2000 m; modulus construitur ut sustineat duras conditiones fabricae sine reductione functionis.
Simplificatio connexorum et custodiae – Numeratio clara terminalium et singuli LED status accelerant installationem, commissionem et investigationem defectuum, minuentes medium tempus ad reparationem (MTTR).
Certificatus TÜV pro Securitate Functionali (1794‑IB16) – Licet 1794‑IB8 non sit certificatus TÜV pro SIL, varians 1794‑IB16 offert facultatem SIL 2, demonstrans commitmentem Rockwell ad securitatem et permittens integrationem securitatis systematis per modulos similem formam habentes.
