Configured for low-level analog signal acquisition in Experion PKS DCS platforms, the Honeywell MC-TAIL02 51304437-150 (MC-TAIL02 Low-Level Analog Input FTA) provides direct physical/electrical execution. The field termination assembly processes incoming sensor signals across 8 analog input channels, converting 0-10 VDC inputs with a 5 ms response time into digitizing backplane communications.

4-20 mA HART Loop Protocol and Channel Isolation
The MC-TAIL02 features galvanic isolation rated up to 500 VDC to prevent common-mode electrical transients from corrupting low-level analog signal channels. Active signal processing paths accommodate 4-20 mA HART loop protocol instruments alongside 0-10 VDC sensors without introducing cross-talk or measurement drift. Channel-to-channel isolation networks decouple sensitive analog-to-digital processing logic from high-voltage field disturbances, preserving data accuracy across process control networks.
Frequently Asked Questions
Q: What is the isolation voltage rating between the field signals and system electronics? A: The field termination assembly provides electrical isolation rated up to 500 VDC between input channels and backplane circuitry.
Q: Can the MC-TAIL02 be hot-swapped while the 24 VDC system power is active?
A: No. System power to the specific termination slot must be isolated prior to hardware removal or insertion to prevent signal corruption and contact damage.
Field Installation Guidelines
Disconnect the main 24 VDC power feed before installing or wiring the field termination assembly.
Mount the 0.5 kg assembly securely inside the cabinet rack using designated mounting hardware.
Terminate 0-10 VDC field signal lines onto the terminal block, ensuring screw fasteners engage with a minimum of 5 full threads.
Route low-level analog input wiring in separate conduits from high-voltage AC conductors by at least 200 mm to suppress noise coupling.
Ground field cable shielding at a single point on the cabinet earth ground bar to maintain +/-0.5% full-scale measurement accuracy.
