Heat Dissipation: 10.5 W (single); 16.2 W (redundant pair)

Communication

Fieldbus: Redundant 2 Mbps backplane (I/A Series)

Protocol: Foxboro proprietary + HART pass‑through

Data Update: 50 ms (default)

HART Support: HART 5/6/7 (per channel)

Basic Installation & Usage

Mounting

Snap into standard I/A Series DIN rail or baseplate.

Secure latch; ensure full seating for backplane contact.

Wiring

Connect intelligent transmitters (pressure/flow/level) and analog devices to P0500RY termination plug.

Transmitter input: 2‑wire (loop‑powered, HART).

Analog output: 2‑wire to valve/actuator; common ground not required (isolated).

Use shielded twisted pair; separate analog/digital cables.

Configuration (I/A Series Software)

Set channel mode: Intelligent Input (HART) / Analog Output (0–20 mA).

Configure AO range (0–20 mA / 4–20 mA) and scaling.

Enable HART (1200 bps); set NE 43 fault thresholds.

Assign failsafe state (hold / 0 % / 100 %) for AO.

Enable diagnostics (short circuit, open load, HART comms).

Operation

RUN (green): module ok; FAULT (red): error (comms/power/channel).

Channel LED: ON = active; FLASH = fault; HART = HART communication.

Monitor HART PV/SV/diagnostics and AO values in HMI.

Maintenance

Hot‑swap faulty module (no shutdown; wiring intact).

Inspect termination plug wiring/shields/grounds annually.

Update firmware via I/A Series software.

Calibration: Not required (factory‑calibrated; on‑board diagnostics).

Typical Applications

Interface for HART intelligent transmitters (pressure/flow/level/temp).

Analog control outputs for valves, actuators, and VFDs.

Mixed intelligent/analog I/O for skids and package units.

Migration of legacy FBM04/FBM05 to 200‑series FBMs.
