Foxboro FBM237 P0916CC Analog Output Module
Foxboro FBM237 P0916CC Analog Output Module. Brand New Original Stock with Global Shipping.
Description
The Foxboro FBM237 P0916CC, also cataloged as the FBM237 Analog Output Module, operates as a dedicated hardware component for multi-channel analog signal execution within Foxboro I/A Series DCS platforms. It provides eight channel-isolated 0 to 20.4 mA DC analog output channels and communicates with associated FCM or FCP modules via the module fieldbus.

Process Control Communication & HART Protocol Compatibility
The module channels meet the impedance requirements for HART high-impedance devices, allowing integration within HART loops without interfering with digital communications between field devices and Hand-Held Communicators (HHC). Galvanic isolation up to 600 VAC withstands transient potentials applied between channels or to earth ground for one minute. Additionally, output channels feature short-circuit limits of approximately 25 mA DC to safeguard internal loop circuitry under field line fault conditions.
Frequently Asked Questions
Q: Are redundant output channel pairs isolated from each other when wired in a redundant configuration?
A: No. When configured in redundant pairs, the outputs are connected by a common field I/O connector and are therefore not galvanically isolated from each other, though individual non-redundant channels maintain independent channel-to-channel isolation.
Q: What are the primary impedance limits and loop driver parameters for the output channels?
A: Each individual output channel drives 0 to 20.4 mA DC loops into a maximum load resistance of 750 Ohms, maintaining a compliance voltage of 18 VDC at 20.4 mA DC at the I/O terminals.
Field Installation Guidelines
Mount the module into its baseplate slot until the connector fully seats into the backplane module fieldbus architecture. Ensure field signal cabling adheres to specified compliance voltage limits and routing distances based on total loop resistance. Connect 24 VDC power supply connections to the redundant input terminals, ensuring supply tolerances remain within +5% and -10%. Ground field cable shields at cabinet entry points to suppress industrial electromagnetic interference prior to applying field loop power.
