FAQ

Q1: What is the Honeywell 51304453-150 (MC-TAIH02) used for?
It is a 16-channel High-Level Analog Input / Smart Transmitter Interface Field Termination Assembly for Honeywell TDC 3000 / TPS / Experion PKS DCS. It provides field wiring termination and routing for analog signals, connecting field transmitters to the DCS I/O processor .

Q2: How many channels does it have?
16 differential input channels .

Q3: Is the MC-TAIH02 an active module or a passive FTA?
It is a passive Field Termination Assembly. It terminates and routes field signals but does not perform analog-to-digital conversion or signal processing. Several third-party listings incorrectly describe it as an active module with Modbus RTU or single-channel functionality .

Q4: Is this FTA conformally coated?
Yes. The "MC-" prefix and G3 harsh atmosphere rating indicate conformal coating .

Q5: What IOP modules are compatible?
The MC-PAIH03 (High Level Analog Input Processor) and MU-PSTX03 (Smart Transmitter Interface Processor) .

Q6: What input signal types are supported?
Voltage, current (2-wire or self-powered), and Honeywell DE protocol .

Q7: What is the current-limiting specification?
Each channel incorporates a 145 Ω non-fused current-limiting resistor for Class 1, Division 2 interfacing .

Q8: What is the mounting size and terminal type?
Size A, with compression terminals accepting up to 14 AWG .

Q9: What is the weight?
Conflicting sources: 0.3 kg , 0.35 kg , 0.45 kg . Verify against official Honeywell documentation.

Q10: Is this a current or legacy product?
The TDC 3000 / TPS / Experion PKS is a legacy/mature platform. Confirm current availability and lifecycle status with Honeywell or an authorized distributor.
