Description
The Foxboro FBM240 (Part Number: P0917GZ) is a high-density, high-reliability discrete output module designed for the EcoStruxure Foxboro DCS (formerly I/A Series) automation platform. As part of the 200 Series Fieldbus Modules, the FBM240 provides the interface between the DCS Field Control Processors (FCP) and field-located final control elements such as solenoids, relays, and motor starters.
The “Redundant Ready” designation signifies that the module is capable of operating in a redundant pair. When two FBM240 modules are installed on a redundant baseplate, they function as a single logical unit, providing bumpless switchover and continuous process control in the event of a single module failure.

Technical Description & Features
- Output Switching: The FBM240 utilizes solid-state switching technology to manage DC loads. It requires an external DC power source to energize the field loads, providing high current-carrying capacity for industrial actuators.
- Redundancy Logic: In a redundant configuration, the “Active” module drives the outputs while the “Standby” module monitors the bus and hardware health. If a fault is detected in the active unit, the standby unit assumes control within milliseconds without affecting the field state.
- Fault Protection: Each channel includes thermal and short-circuit protection. The module can detect and report “Open Circuit” or “Short Circuit” conditions to the control processor, allowing for proactive maintenance.
- Isolation Integrity: Each output channel is individually isolated from the internal system logic. This robust galvanic isolation protects the sensitive DCS backplane from field-side electrical surges or ground faults.
- Status Indicators: The front panel includes a dedicated LED for each of the 8 channels to show the current output state, along with system-level LEDs (Ready, Run, Fault) for module health diagnostics.

Installation & Usage Guidelines
- Baseplate Selection: For non-redundant operation, use a standard 200 Series baseplate. For redundant operation, the FBM240 must be installed on a redundant baseplate (e.g., P0926HF) with its partner module in the adjacent slot.
- Termination Assembly (TA): To connect the 8 output channels to field devices, a compatible Termination Assembly is required. The TA provides the terminal blocks for field wiring and the entry point for the external DC power supply.
- External Power: Ensure the external DC power supply is sized to handle the total current draw of all 8 channels simultaneously (up to 8 Amps). Use fused power distribution for added safety.
- Software Configuration: Use the Control Editor or IACC to configure the module. Assign the FBM type as FBM240 and map the Boolean output tags to the respective hardware channels.
- Hot Swapping: The module supports hot swapping. To replace a module in a redundant pair, simply pull the faulted module and insert a new one; the system will automatically synchronize the new module.
