Honeywell CC-TAOX01 Analog Output Module 51308351-175

Honeywell CC-TAOX01 Analog Output Module PWA 51308351-175

The Honeywell CC-TAOX01 (Part Number: 51308351-175) is a 16-channel high performance analogue output (AO) module for the Honeywell Experion® Process Knowledge System (PKS) and C300 control systems. • This unit is a Series-C Input/Output Termination Assembly (IOTA) module, providing very accurate 4–20 mA current loops to key field devices such as control valves, actuators, recorders and I/P converters.

This non-redundant module is designed for harsh industrial environments and offers deterministic process control, advanced loop diagnostics and smooth connection with Honeywell’s Control Execution Environment (CEE). From land-based petrochemical processing applications to automation networks on maritime vessels, the CC-TAOX01 guarantees steady-state precision and high system availability.

Key Features

1. 12-Bit Precision Control: Enables accurate and reliable 4-20mA current control to field devices, optimising actuator accuracy and continuous process loops.
2. Integrated dual-modem HART: Supports bi-directional connection with smart devices, so that instrument engineers can perform remote device configuration, tuning and asset diagnostics directly through the system.
3. Rugged Industrial Durability: Conformal coating by default protects the underlying components against humidity, dust, heat cycling and airborne chemical pollutants.
4. Hot-Swappable Infrastructure: Supports on-line replacement of modules without interrupting the power of active systems or affecting adjacent control channels.

Installation Guide:

• Defeating Cabin Vibration-Induced Failures: Even though the Series-C form factor latches securely onto its DIN rail, cyclic low-frequency hull vibrations can slowly back out field wiring over time. Always utilize insulated ferrule terminals on your 4–20 mA loops and check torque specs on the screw terminals during routine semi-annual maintenance turnarounds.
• Managing the Thermal Envelope: The 51308351-175 PWA is rated for up to 60°C in tightly enclosed spaces. In tropical transits or closed machinery spaces where ambient cabinet temps can spike, ensure there is active forced-air ventilation across the rack. Heat is the number one cause of premature drift in 12-bit DAC chips.
• HART Multi-drop Tuning: If exploiting the dual-modem HART capability for smart positioners, make sure your total loop impedance does not drop below 250Ω. If using low-impedance actuators, an external resistor must be wired in series for the HART modem to successfully couple its AC digital signals onto the current loop.
