FBM17

Basic Information

Model: FBM17 (including variants FBM17A/B/C/D)

Manufacturer: Foxboro / Schneider Electric

Type: Mixed I/O Module (4AI/4DI/2AO/4DO)

System: I/A Series DCS

Status: Obsolete, spare part only

Key Features

Mixed-signal design integrating analog and discrete I/O in one module.

Multiple variants (A/B/C/D) for different voltage and current requirements.

16-bit high-resolution analog processing for precise control.

Full galvanic isolation ensures safety and suppresses electromagnetic interference.

Redundant fieldbus communication enhances system reliability.

Onboard LED status indicators and self-diagnostic function for easy maintenance.

Supports online hot-swap replacement without system downtime.

Application

Interface with field devices requiring both analog and discrete signals: transmitters, sensors, valves, and motors.

Used for small-scale process control and monitoring in chemical, petrochemical, power, oil & gas, and water treatment industries.

Ideal for space-saving I/O solutions in compact control rooms.
