Foxboro P0916DB TERMINATION ASSEMBLY

Foxboro P0916DB TERMINATION ASSEMBLY

Description

The FBM244 module contains four 0 to 20 mA galvanically isolated analog input and output channels (eight total). The FBM244 supports any mix of standard 4 to 20 mA devices and HART devices.

Each input channel accepts an analog sensor input such as a 4 to 20 mA transmitter or a self-powered 20 mA source. Each output channel drives an external load and produces a 0 to 20 mA output.

The module performs the signal conversion required to interface the electrical input/output signals from the field sensors and actuators to the redundant Fieldbus.

This module executes the analog I/O application program. The configurable options for this program are Fail-Safe Configuration (Hold/Fallback), Analog Output Fail-Safe Fallback Data, (on a per channel basis), Fieldbus Switching Enable and Fieldbus Switching Time. The module does not provide DPIDA support.

When connected to the appropriate TAs, the FBM244 module provides functionality formerly provided by the 100 Series FBM I/O subsystem. TAs are available which support the functionality of the 100 Series FBM04, when the FBM04 is used with HART devices.

Feature

• Four 0 to 20 mA analog input channels, used for a HART analog sensor input such as a 4 to 20 mA transmitter or a self-powered 20 mA source
• Four analog output channels, used to drive an external load and produce a 0 to 20 mA output
• Support for the HART universal commands necessary to interface the field device with the Foxboro Evo™ system database Both inputs and outputs are galvanically isolated
• Compact, rugged design suitable for enclosure in Class G3 (harsh) environments
• Termination Assemblies (TAs) for locally or remotely connecting field wiring to the FBM244
• Termination Assemblies for per channel internally and/or externally loop powered transmitters
