Product Overview
The Honeywell 8C-TAIX51 (Part Number: 51306979-175) is a high-performance Analog Input Module designed for the Series 8 I/O architecture. This module provides 16 dedicated channels for precise 4-20 mA current signal acquisition from field transmitters. It integrates directly with the Honeywell Experion PKS and C300 controllers, converting critical process variables into 16-bit digital values. We supply this unit as 100% Brand New and Original, featuring a non-redundant IOTA configuration for cost-effective, high-accuracy process monitoring.

Engineering Advantages
-
Rapid Signal Acquisition: A 50 ms input scan rate ensures the controller receives real-time data from the field. This speed allows for tighter control loops in dynamic processes such as turbine monitoring or chemical reactions.
-
High-Resolution Accuracy: The 16-bit A/D converter delivers exceptional granularity, allowing the system to detect minute changes in 4-20 mA signals. This precision minimizes measurement errors and improves overall product yield.
-
Superior Interference Mitigation: With a 70 dB Common Mode Rejection Ratio (CMRR), the 8C-TAIX51 effectively filters out industrial electrical noise. This ensures signal integrity even when field cables run near high-voltage equipment or motors.
-
Compact Non-Redundant Design: The 6-inch IOTA mounting requirement and lightweight profile (0.26 kg) make it an ideal choice for space-constrained cabinets where redundancy is not a primary requirement, significantly reducing hardware costs.
-
Ruggedized for Harsh Fields: The module operates within an extreme temperature range of -40°C to +70°C. Standard protective measures against environmental stressors ensure long-term reliability in refineries and power plants.
FAQs
1. Does the 8C-TAIX51 support millivolt or thermocouple inputs?
The 8C-TAIX51 51306979-175 focuses specifically on 4-20 mA current loops. For thermocouple or low-level mV sources, you should select the specialized T/C input version of the Series 8 modules to ensure proper cold-junction compensation.
2. Can I install this module on a redundant IOTA?
The 8C-TAIX51 is designed for non-redundant applications. It typically mounts on a 6-inch non-redundant IOTA. For mission-critical loops requiring failover capability, a redundant-capable module and corresponding IOTA should be used.
3. Is this module hot-swappable?
Yes. Like most Honeywell Series 8 I/O components, the 8C-TAIX51 supports hot-swapping. You can remove and replace the module without disconnecting field wiring or shutting down the entire I/O rack.
4. What is the standard warranty for a new unit?
We provide a 12-month warranty on all Brand New and Original 8C-TAIX51 modules. Each unit undergoes rigorous factory testing to meet Honeywell’s strict quality standards before shipment.
