The FBM242 belongs to the Foxboro I/A Series from Schneider Electric. This module provides sixteen discrete output channels. You can use it with externally sourced excitation voltages. It supports multiple voltage ranges including 15-60 V dc and 120 V ac/125 V dc. Additionally, it handles 240 V ac applications. Each input and output channel has galvanic isolation. This ensures reliable operation even in noisy industrial environments.
Furthermore, the FBM242 executes Discrete I/O or Ladder Logic programs. You can configure several options including Input Filter Time, Fail Safe Configuration, and Fail Safe Fall-Back. You also choose between Sustained or Momentary Outputs. Therefore this module offers great flexibility for various control applications.
The FBM242 includes sixteen discrete output channels. Each channel supports a maximum load current of 2.25 A. In-rush current reaches 8 A for 20 ms at 30°C. The on-state voltage drop stays below 0.2 V at full load. Off-state leakage current is only 0.1 mA maximum.
Moreover, each channel is galvanically isolated from all other channels and earth ground. The module withstands 600 V ac applied for one minute between any channel and ground. This high isolation protects your control system from electrical faults.
Output Channels: Sixteen isolated channels
Applied Voltage: 15 to 60 V dc (maximum)
Load Current per Channel: 2.25 A maximum
In-Rush Current: 8 A for 20 ms per channel at 30°C; 6.4 A at 70°C
On-State Voltage Drop: 0.2 V maximum at 2.25 A
Off-State Leakage Current: 0.1 mA maximum
Power Requirements:
Input Voltage Range (Redundant): 24 V dc +5%, -10%
Maximum Consumption: 3 W at 24 V dc
Heat Dissipation: 6.5 W maximum at 24 V dc (all outputs at 1.5 A each)
Communication: The FBM242 communicates with its associated FCM or FCP via the redundant 2 Mbps module fieldbus.
The FBM242 operates in temperatures from -20 to +70°C (-4 to +158°F). The termination assembly PVC version runs from -20 to +50°C (-4 to +122°F). Relative humidity ranges from 5 to 95% noncondensing.
This module suits Class G3 harsh environments as defined in ISA Standard S71.04. It has passed exposure testing according to EIA Standard 364-65, Class III. Therefore you can install it in aggressive industrial settings.
Vibration tolerance: 0.75g (5 to 500 Hz)
Operating altitude: -300 to +3,000 m (-1,000 to +10,000 ft)
Storage altitude: -300 to +12,000 m (-1,000 to +40,000 ft)
The FBM242 complies with European RoHS Directive 2011/65/EU including amendments 2015/863 and 2017/2102. It also holds IECEx certification. No calibration is required for the module or termination assembly. This simplifies installation and reduces maintenance costs.
First, mount the FBM242 in a suitable chassis or rack. Ensure proper grounding to avoid electrical noise interference. Next, connect the redundant 24 V dc power supply. Verify the voltage stays within +5% and -10% of nominal. Then wire your field devices to the termination assembly. Each output channel can drive loads up to 2.25 A continuous.
For inductive loads, add a protective diode or metal oxide varistor (MOV) across the load. This prevents voltage spikes from damaging the output channels. Finally, configure the module through your Foxboro control software. Set Input Filter Time, Fail Safe behavior, and output type (Sustained or Momentary) as needed.

1. What is the maximum load current per channel on the FBM242?
Each channel supports 2.25 A maximum continuous load current. In-rush current can reach 8 A for 20 ms at 30°C.
2. Does the FBM242 require calibration after installation?
No, the FBM242 requires no calibration. The module and termination assembly work out of the box. This saves time during commissioning.
3. Can I use this module with inductive loads like relays or solenoids?
Yes, but you must add a protective diode or MOV across the inductive load. This protects the output channel from voltage spikes.
4. Is the FBM242 suitable for harsh chemical environments?
Yes, it is certified for Class G3 harsh environments per ISA S71.04. It withstands contaminated industrial atmospheres.
5. How does the FBM242 communicate with the main controller?
The FBM242 uses a redundant 2 Mbps module fieldbus to communicate with its associated FCM or FCP controller. This provides reliable data transfer.
