Honeywell TC-FOA041 Analog Output Module – 4-Channel Precision Control

Product Overview

When analog output precision and reliability are critical in your control system, the Honeywell TC-FOA041 analog output module provides a robust solution. This module features four single-ended, non-isolated outputs with 12-bit plus sign resolution, ensuring accurate signal conversion for demanding industrial applications. Designed for seamless integration, it offers user-configurable voltage and current outputs, making it a versatile choice for process control engineers.

Technical Specifications

The TC-FOA041 delivers a voltage resolution of 2.56mV per count and a current resolution of 5.13µA per count. Data is formatted as left-justified 16-bit 2’s complement, and conversion uses pulse width modulation with a maximum conversion rate of 1.024ms for all channels. The output current terminal provides 0mA output until configuration, with user-selectable 4-20mA or 0-20mA ranges. The output voltage terminal offers 0V until configuration, with ±10V or 0-10V options. Step response to 63% of full scale is 24ms, and current load on maximum voltage output is 3mA. Resistive load on mA output ranges from 15 to 750 ohms. Absolute accuracy for the voltage terminal is 0.133% of full scale at 25°C, and for the current terminal it is 0.425% of full scale at 25°C, including offset, gain, non-linearity, and repeatability errors. Accuracy drift with temperature is 0.0045% of full scale per °C for voltage and 0.0069% per °C for current. No calibration is required. Isolation is tested at 850V DC for 1 second between user and system, with no isolation between individual channels. A single green power indicator is provided. Flexbus current is 20mA at 5V DC, maximum power dissipation is 4.5W at 31.2V DC, and maximum thermal dissipation is 15.3 BTU/hr at 31.2V DC. The keyswitch position is 4.

Industry Applications

The TC-FOA041 is ideal for applications requiring precise analog output control, such as valve positioning, variable frequency drive setpoints, and process variable regulation in chemical, oil and gas, and manufacturing plants. Its configurable output ranges allow easy adaptation to existing field devices, reducing commissioning time. For maintenance engineers, the module’s non-isolated design simplifies wiring while maintaining system integrity, and the fast 1.024ms conversion rate supports responsive loop control.

Installation & Setup Guidance

Mount the TC-FOA041 in a suitable enclosure within the specified operational temperature range of 0 to 55°C (32 to 131°F). Use 12 gauge (4mm²) stranded wire maximum with 3/64 inch (1.2mm) insulation maximum for field connections. The module requires an external 24V DC nominal power supply with a voltage range of 19.2 to 31.2V DC (including 5% AC ripple) and draws 70mA at 24V DC (not including outputs). Configure output ranges via the host system before enabling outputs to ensure safe startup. Verify the keyswitch position is set to 4 for correct addressing.

Maintenance & Reliability

Routine inspection of the TC-FOA041 should focus on verifying power supply voltage within the 19.2 to 31.2V DC range and checking for loose connections. The module’s robust design withstands operating shock of 30g peak acceleration and vibration of 5g at 10-500Hz per IEC 68-2-6. Storage temperature range is -40 to 85°C (-40 to 185°F), and relative humidity tolerance is 5 to 95% non-condensing during operation. No calibration is required, reducing maintenance overhead. For long-term reliability, ensure the module is not exposed to condensation or excessive thermal cycling.

Compatibility & Integration

The TC-FOA041 integrates with Honeywell control systems and is certified for Class I Division 2 and Class I Zone 2 Group IIC hazardous locations, as well as Groups A, B, C, D. It communicates via the Flexbus backplane, drawing 20mA at 5V DC. Verify compatibility with your specific controller and backplane before installation. For replacement or upgrade projects, the TC-FOA041 offers a direct analog output solution with no calibration requirements, simplifying system updates.

Selection Guide & Purchasing Advice

Before ordering, confirm that your system supports the TC-FOA041’s keyswitch position 4 and that the external 24V DC power supply meets the 19.2 to 31.2V DC range. Consider the number of analog output points needed—this module provides four single-ended outputs. For applications requiring isolated channels, note that the TC-FOA041 does not provide channel-to-channel isolation.
