2.Main Features

Analog input and output:

The FBM204 module contains four 20mA DC analog input channels and four 20mA DC analog output channels.

Each input channel can accept analog sensor input,such as 4~20mA transmitter or self-powered 20mA signal source.

Each output channel can drive an external load and generate 0~20mA output.

Electrical isolation:

The input/output is electrically isolated from other channels and ground wires,which improves the safety and stability of the system.

High precision:

The module uses Sigma-Delta data conversion technology to achieve high-precision signal conversion.

A new analog input reading is provided every 25 milliseconds with a configurable integration period to eliminate the effects of any process and/or noise and power line frequency.

Configurable Options:

The FBM204 performs analog I/O applications,providing configurable options such as conversion time,fail-safe configuration(hold/fallback),and analog output fail-safe fallback data(per channel).

Rugged Design:

The module features rugged extruded aluminum housing circuitry suitable for cabinets in G3 grade(harsh)environments.

Supports DPIDA:

The Fieldbus Module(FBM)can perform Distributed PIDA(DPIDA)applications to provide fast control loops operating within.

Terminal Assemblies:

Terminal Assemblies(TAs)are provided for connecting field wiring to the compact FBM204 locally or remotely.

TAs are also used in output bypass stations to hold outputs during maintenance operations.
