Analog Input Module 8C-TAIXA1 51307127-175 Honeywell

Product Description

Configured for 4-20 mA current signal acquisition in the Honeywell Series 8 I/O system, the Honeywell 8C-TAIXA1 51307127-175 (8C-TAIXA1 Analog Input Module) provides 16 single-ended input channels. The module accepts current signals from 2-wire or self-powered transmitters and uses 16-bit A/D conversion. It also supports HART-capable devices, galvanic isolation, fast loop scanning, and optional redundancy.

Hardware Specifications

4-20 mA HART Signal Handling and Isolation

The 8C-TAIXA1 receives 4-20 mA signals from field transmitters through 16 single-ended input channels. The module supports both 2-wire and self-powered transmitter configurations. A 250 ohm input path supports the specified 4-20 mA signal range.

The module also supports HART-capable devices for Configure / Status functions. Therefore, the analog loop carries the primary process signal while the HART communication layer provides device configuration and status information.

Galvanic isolation separates the field-side electrical interface from the associated system circuitry. The module provides internal or external field power selection, allowing the installation to match the transmitter power arrangement.

Frequently Asked Questions

Q: What input signals does the 8C-TAIXA1 accept?
A: The module accepts 4-20 mA current inputs from 2-wire or self-powered transmitters. The specified input path uses 250 ohm resistance.

Q: How many analog input channels are available?
A: The module provides 16 single-ended analog input channels with 16-bit A/D conversion.

Q: Does the module support HART devices?
A: Yes. The supplied specifications identify HART capability and support for Configure / Status functions for HART devices.

Field Installation Guidelines

Install the module according to the applicable Honeywell Series 8 I/O hardware documentation and cabinet requirements.

• Verify the module model and terminal assignment before wiring.
• Confirm the transmitter type before selecting internal or external field power.
• Route 4-20 mA signal wiring separately from high-voltage and high-current conductors.
• Use shielded signal cable where the installation requires protection against electromagnetic interference.
• Connect cable shields according to the site grounding and Honeywell installation practice. Avoid unintended shield current paths.
• Verify loop polarity and transmitter power requirements before energizing the circuit.
• For HART devices, maintain the specified loop resistance and wiring arrangement required by the field device.
• Confirm galvanic isolation requirements before connecting external field power.
• Inspect all terminal connections before applying the 24 VDC system supply.
• Do not apply operating-temperature, hot-swap, or power-consumption limits that are not stated in the available module data.
