Foxboro RH101AG Field Terminal Board (FTA)

Foxboro RH101AG Field Terminal Board (FTA)
Brand: Schneider Foxboro (a subsidiary of Schneider)
System: I/A Series Evo Compact 200 Series DCS Universal I/O Accessory Terminal Block

I. Model Explanation: RH101AG
RH101: 200 series FBM card-specific backplane type FTA terminal board series
A: General isolation analog baseplate, supporting AI/AO/pulse/DI, with HART compatibility
E: Spring cage type quick-connect terminals (no need for screwdriver, press and plug), single-channel independent protection
Series differentiation: RH101AG = Screw compression terminals, RH101AG = Spring terminals, both have the same channel specifications, only the wiring method is different

The only compatible I/O card
RH101AE is one-to-one matched with FBM247 8-channel universal configurable I/O module resource…
FBM247: 8 channels of fully isolated channels, single-channel software-free switching AI/AO/DI/pulse counting, native support for HART intelligent transmitters
One FBM247 rack slot corresponds to one RH101AG terminal board, directly plugged into the rack backplane I/O interface, no intermediate cables required

Hardware Channel Specifications
1. Channel Capacity
8 channels of fully isolated channels, each channel with independent fuse
Single channel software configuration:
AI: 4–20mA, 0/1–5V, thermocouple J/K/T/E/R/S/B, Pt100/Cu50 thermoresistor
AO: 4–20mA output (maximum load 600Ω)
DI: Passive contacts, 24VDC voltage input
PI: Low-speed pulse counting signal
Support HART overlay communication, can read transmitter parameters online, calibrate instruments
2. Terminal Structure Characteristics
Spring cage type wiring, compatible with 0.5~1.5mm² shielded signal lines, shock-resistant and anti-loosening, suitable for chemical, power plant vibration cabinets
Each channel has an independent miniature fuse, single-channel short circuit does not affect the other 7 channels of signals
Channel-to-channel, channel-to-ground 2kV isolation, suppresses electromagnetic interference from frequency converters, large-power motors
Built-in shielded grounding busbar, unified instrument shielding layer grounding, reduces signal drift
3. Installation Method
Rack backplane direct insertion installation, with mechanical lock, supports plug-and-pull replacement of terminal boards without stopping the machine
Standard 200 series I/O rack slot, single slot occupies, compact and saves cabinet space

Electrical and Environmental Parameters
Power supply: Unified 24VDC power supply from FBM247 backplane, terminal board has no independent power supply
Operating temperature: -20℃ ~ +70℃; Storage: -40℃ ~ +85℃
Protection level: IP20 (used in control cabinets)
Certifications: CE, UL, DNV shipyard certification, suitable for oil and gas, chemical, power plant, water treatment, metallurgy

Typical Application Scenarios
Petrochemical / refining plant temperature, pressure, flow, level HART transmitters collection
Power plant boiler, steam turbine auxiliary control PID regulating valve 4–20mA output control
Distributed photovoltaics, pump station pulse flow metering, switch quantity point collection
