YOKOGAWA FIO System (compatible with Vnet/IP) Hardware Specification Manual

ANB10  -  E/ANB11  -  E/ANR10  -  E Hazardous Area ≤ 88

ANB10  F/ANB11  F/ANR10  F Hazardous area ≤ 80

AFV10D/AFV30D (dual redundancy) non hazardous area factor A ≤ 20; Factor A+Factor B ≤ 65

（2） Spacing and isolation requirements

The intrinsic safety zone and non intrinsic safety zone must maintain a distance of ≥ 50mm. The node unit (ANB10 ) needs to be equipped with an insulation partition (T9083NA), and the FCU (AFV10 /AFV30 ) needs to be equipped with an insulation partition kit (T9083ND);

The built-in isolation barrier module needs to be installed separately from other modules to avoid electromagnetic interference.

（3） Special environment and module limitations

Wide temperature environment (60-70 ℃): A maximum of 4 IOMs can be installed on a single node, and slots need to be left between modules. Installation of AAI543-  6 /-  F  (quick response type) is prohibited;

TC input module (AAT141/AAT143): It should be kept away from heat sources (such as CP461, bus interface module), avoid direct airflow, and can only be installed adjacent to designated modules (AAT141, AAR181, etc.);

Dual redundancy configuration: I/O modules need to be installed in paired slots (IO1-IO2, IO3-IO4, etc.), and empty slots need to be protected with a false cover plate (ADCV01).

Compliance standards

Safety standards: CSA, CE Marking, EAC Marking;

EMC standards: CE Marking, EAC Marking, RCM, KC Marking (excluding built-in isolation barrier modules);

Explosion proof standards: CSA/FM Non Intrinsic, Type n, Type i, FM certified.
