Honeywell 51305887-150 MC-TAIH14 High Level Analog Input Board W/HART

Configured for analog-to-digital signal conversion in TDC 3000 Experion PKS networks, the Honeywell 51305887-150 (MC-TAIH14 High Level Analog Input Board W/HART) provides direct physical/electrical execution.

Hardware Specifications

Fieldbus Integration & Channel Isolation

The MC-TAIH14 board processes 8 independent high-level voltage channels, converting 0 to 10 VDC field inputs into digital bus structures at 1000 samples/sec per channel. Operating with 4-20 mA HART loop protocol architectures and Ethernet communications, the assembly maintains channel-to-channel isolation to eliminate common-mode noise and ground potential differentials across process control loops.

Frequently Asked Questions

Q: What is the input impedance per channel on the 51305887-150 board?

A: Each of the 8 high-level analog input channels features an internal input impedance of 1 Mohm.

Q: Can the board be installed or removed under live system power?

A: Live maintenance requires removing field terminal connections and disconnecting the 24 VDC bus to prevent voltage spikes across signal lines.

Q: What analog-to-digital conversion resolution does the board provide?

A: The onboard analog-to-digital converter executes signal sampling at a 12-bit resolution across all 8 input channels.

Field Installation Guidelines

1. Disconnect all 24 VDC power lines and field signal loops prior to mounting the MC-TAIH14 assembly in the carrier chassis.
2. Route 0 to 10 VDC analog signal wires using individually shielded twisted-pair cables to protect low-level signal integrity against external electro-magnetic interference.
3. Connect signal cable shields to the main enclosure earthing rail at a single point to prevent circulating ground currents.
4. Mount the board onto the chassis slot rails, ensuring physical alignment before tightening retention screws to 0.5 Nm torque.
