Foxboro FBM242
The FOXBORO FBM242 is a discrete output module designed for the Foxboro I/A Series distributed control system (DCS). It provides 16 channels for interfacing with external discrete output devices such as relays, solenoids, and contactors. The module requires an external power supply to energize the field circuits and offers galvanic isolation for each output channel from other channels and ground, ensuring reliable operation in industrial environments. It supports the execution of Discrete I/O or Ladder Logic programs and offers configurable options like Input Filter Time and Fail-Safe Configuration for the outputs. Various Termination Assemblies (TAs) are available to accommodate different voltage levels, current limiting, fusing, and relay output configurations.
Key Characteristics:
- 16 Discrete Outputs: Provides sixteen independent output channels.
- Externally Powered: Requires an external power supply for field circuits.
- Wide Voltage Range Support: Compatible with discrete output signals at 15 to 60 V DC, 120 V AC / 125 V DC, and 240 V AC (depending on the Termination Assembly).
- High Current Rating: Supports a maximum load current of up to 2 A per channel (at 60 V DC, may vary with voltage and TA). Some sources mention up to 2.25 A.
- Galvanic Isolation: Each output channel is isolated from other channels and ground.
- Rugged Design: Suitable for harsh industrial environments (Class G3
