1. Product Positioning and Functions
Product Category:
This module belongs to the Foxboro I/A Series or FBM Series (depending on the specific system architecture).
Core Functions:
-
Signal Acquisition:
Responsible for converting analog signals (such as 4–20 mA, 0–10 V) from field instruments (e.g., pressure gauges, thermometers, flow meters) into digital signals, which are then transmitted to the host computer or DCS. -
Signal Output:
Converts digital commands issued by the DCS into analog signals required by field devices, enabling control of actuators such as valves and motors.
