Overview
The Foxboro FBM242 P0916TA is a Fieldbus I/O module in the Foxboro I/A Series DCS, designed for discrete output signal handling. It provides 16 output channels for externally sourced signals and communicates with the control system through a redundant 2 Mbps module fieldbus. Furthermore, its 24 VDC supply and modular baseplate mounting support integration into the installed I/O configuration.
Functional Description
The FBM242 handles discrete output signals between the DCS and external field devices. Its 16 output channels support externally sourced outputs, allowing the module to transmit discrete control states to connected equipment.
Meanwhile, the redundant 2 Mbps fieldbus provides the communication path between the I/O module and the control system. This arrangement separates field output handling from system-level communication.
Configuration and Operating Conditions
The module operates with a 24 VDC supply and mounts on a modular baseplate. Its specified operating temperature range is -20 to +70 deg C. These parameters should be considered when checking the installed baseplate configuration, power supply and cabinet operating conditions.
