Product Overview
The Honeywell MC-TAIL03 (Part No. 51309202-175) is a low-level analog input Field Termination Assembly (FTA) used in Honeywell Experion PKS and Series C I/O systems.
It is designed to handle low-level analog signals, typically from sensitive field instruments such as thermocouples, RTDs, millivolt-level sensors, and specialized low-energy measurement devices. The module provides signal conditioning and structured termination before forwarding signals to the system I/O processor.
Compared with high-level analog input modules, this unit is optimized for small signal ranges requiring higher precision and noise immunity.

Function and Working Principle
The MC-TAIL03 functions as a precision signal interface for low-amplitude analog inputs.
It is responsible for:
- Receiving low-level analog signals from field sensors
- Amplifying and conditioning weak electrical signals
- Converting sensor inputs into stable signals for the I/O system
- Filtering electrical noise and interference
- Transmitting processed signals to control system processors
- Supporting accurate measurement of sensitive instrumentation signals
It does not execute control logic; it ensures accurate acquisition of low-level signals.
