2. Installation requirements

Specific requirements for installation category

The module installation needs to be installed on a modular base plate, which supports horizontal/vertical DIN rail installation or can be adapted to a 19 inch rack through an installation kit; It can also be installed on the 100 series conversion installation structure (refer to PSS 41H-2W8)

TA is installed on 32mm or 35mm DIN rails and can be installed in the same cabinet or adjacent cabinets as the module (with a maximum cable length of 30m)

Wiring specifications support solid/multi strand wires (0.2~4mm ²/24~12AWG), multi strand wires with wire ears (0.2~2.5mm ², compatible with or without plastic sleeves)

Terminal Component (TA) and Cable Configuration

1. TA core parameters (RH924JH)

Specific specifications for TA

Adapt signal 8-channel 4-20mA analog signal/HART digital signal

Authentication Type 1+Type 2 Dual Authentication:

-Type 1: UL/UL-C Class I A-D Group 2 T4, ATEX Ex nA IIC T4 2;

-Type 2: UL/UL-C associated equipment (non flammable field circuit), ATEX IIC Zone 2 associated equipment, meets Class 2 current limiting requirements (below 60VDC/30VAC/100VA)

2. Terminal cable selection

Cables are divided into two categories: "Polyurethane/PVC (Type 1 P/PVC)" and "Low Smoke Zero Halogen (Type 1 LSZH)". The latter is suitable for scenarios that require smoke toxicity and corrosiveness (such as subways and data centers). The commonly used lengths and part numbers are as follows:

Length (m/ft) Type 1 P/PVC Part Number Type 1 LSZH Part Number

0.5/1.6 RH916DA RH928AA

1.0/3.2 RH916DB RH928AB

Summary

FBM214b is Schneider Foxboro ™  DCS is a specialized module designed for integrated acquisition of analog signals and HART digital signals. Its core advantages include 8-channel independent isolation, flexible internal/external power supply, compatibility with multiple versions of HART devices, and adaptability to harsh industrial environments. It is suitable for high-precision acquisition and digital diagnosis of equipment in petrochemical, power, water treatment, and other fields. Its "calibration free" design and hot swappable function reduce maintenance costs, while redundant fieldbus and anti crosstalk components (Cable Balun) ensure the stability and reliability of data acquisition.
