Key Features
The FBM216 provides eight group-isolated input channels, each accepting standard 4–20 mA analog signals or HART Frequency Shift Keying (FSK) digital signals superimposed on the analog input, supporting any mix of conventional analog transmitters and HART smart devices on the same moduleparesource.schneider-electric.com. As a HART master, it integrates per-channel FSK modems for bidirectional communication, enabling the DCS to read real-time process variables, device diagnostics, and perform remote configuration at up to two digital messages per second per channelparesource.schneider-electric.com. It supports HART protocol versions 5, 6, and 7, including universal, common practice, and device-specific commands via telegram pass-through (burst mode not supported)paresource.schneider-electric.com.
High precision is ensured with 15-bit resolution, typical analog accuracy of ±0.075% of full scale (including nonlinearity), and a temperature coefficient of 50 PPM/°Cparesource.schneider-electric.com. The module features strong signal rejection, with common-mode rejection exceeding 100 dB at 50/60 Hz and normal-mode rejection greater than 35 dB at 50/60 Hz, minimizing electrical noise interference in industrial environmentsparesource.schneider-electric.com. Each channel includes a current-limited, voltage-regulated loop power supply with galvanic isolation, supporting both internally and externally powered field transmittersparesource.schneider-electric.com.
Redundancy is a core feature: two FBM216 modules can operate in a master-tracker redundant pair, with field inputs wired to a common termination assemblyparesource.schneider-electric.com. The master module actively processes data, while the tracker synchronizes in real time. If the master fails, the tracker takes over seamlessly with bumpless switchover, ensuring continuous data acquisition without process disruptionparesource.schneider-electric.com.
Rugged construction includes an extruded aluminum enclosure and conformal-coated PCB, rated for ISA S71.04 Class G3 harsh environments to resist dust, moisture, vibration, and wide temperature fluctuationsparesource.schneider-electric.com. Front-panel LED indicators display module power, channel activity, and fault status for quick on-site troubleshooting. Hot-swap capability allows module replacement during system operation without shutting down the DCS or interrupting process controlparesource.schneider-electric.com. The maximum field wiring distance reaches 3030 m (10,000 ft) under optimal conditions, complying with HART FSK physical layer specificationsparesource.schneider-electric.com.
