FBM204 analog input/output module

The FBM204 is an analog input/output module manufactured by Foxboro , primarily used in its I/A Series Distributed Control System (DCS). Below is its detailed information:

1. Basic Parameters

Number of Channels: 4 analog input channels and 4 analog output channels.
Input Signal Ranges: Supports selectable signal ranges, including 4-20mA, 0-10V, ±10V, etc.
Output Signal Ranges: Also supports multiple signal ranges, such as 4-20mA, 0-10V, ±10V, etc.
Accuracy: ±0.1% of full scale.
Resolution: 16-bit.
Update Rate: Updates once every 250µs.

2. Functional Features

Signal Isolation: Achieves electrical isolation between input/output channels and between channels and ground, effectively preventing signal interference and improving the module’s stability and reliability.
Configurable Options: Executes analog I/O applications and provides configurable options such as conversion time, fail-safe configuration (hold/retreat), and analog output fail-safe retreat data (per channel), meeting the needs of different application scenarios.
High-Precision Conversion: Enables high precision through sigma-delta data conversion per channel. The module provides new analog input readings every 25ms, and the integration cycle can be configured to eliminate the impact of any process, noise, and power line frequency.
Compatibility: Electrically compatible with standard HART signals, facilitating communication with other devices that support the HART protocol.
Rugged Design: Features a rugged extruded aluminum housing circuit, suitable for enclosures in Grade G3 (severe) environments, ensuring stable operation in harsh industrial conditions.
Status Indication: The front of the module includes red and green Light-Emitting Diodes (LEDs) that provide visual status indication of FBM functions, allowing users to quickly check the module’s operating status.
