MC-TAIH13 51309138-175 Honeywell Analog Input Board

The Honeywell 51309138-175, also cataloged as the MC-TAIH13 High-Level Analog Input Module, operates as a dedicated hardware component for multi-channel analog signal acquisition within Honeywell TotalPlant Solution (TPS) DCS platforms.

Hardware Specifications

Fieldbus Protocol & Channel Isolation

The MC-TAIH13 conditions and digitizes up to 32 high-level analog inputs across a wide -10 V to +30 V signal range, interfacing directly with temperature, pressure, and flow transmitter loops. Fully integrated with 4-20 mA HART loop protocol architectures and DCS I/O bus networks, the assembly provides hardware filtering and channel-to-channel isolation to block common-mode noise, preventing signal interference from distorting process variable registers.

Frequently Asked Questions

Q: How many analog sensor loops can be wired directly to the MC-TAIH13 assembly?

A: The board features termination points for up to 32 high-level analog input channels.

Q: What input signal voltage range is accepted across the channel terminals?

A: The hardware supports a wide voltage signal range spanning -10 V to +30 V.

Q: Is external logic power required to operate the MC-TAIH13 assembly?

A: Logic power is provided directly through the standard 24 VDC I/O bus interface connected to the assembly.

Field Installation Guidelines

1. Disconnect all 24 VDC power buses and field loop wiring before mounting or replacing the MC-TAIH13 board in the cabinet rack.
2. Route all incoming field sensor lines using shielded twisted-pair cables to safeguard low-level analog signals against electromagnetic interference.
3. Ground cable shields at a single central cabinet earthing point to prevent circulating ground currents across non-isolated references.
4. Align the board with the enclosure mounting rails and secure all retaining screws to ensure proper physical frame grounding.
