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
- Four 0 to 20 mA analog input channels, used for a HART analog sensor input such as a PSS 31H-2S244 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
- 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.
